Long before the Dremel Saw-Max and Rockwell Versacut mini multipurpose circular saws hit the market, Craftsman had a mini circular saw of their own.
The new saw is suitable for plywood and other sheet materials, plastic, light metal, wood boards, cutting tiles and flooring material, and it can help with grout removal. Anyway from what I read it seems Craftsman is introducing the most powerful mini-saw in the market yet with some unique features and a guide system which I had never seen before!
I hate to eat my words, but I talked with the local Sears tool dept Mgr and he said the redesigned tool was fairly new and blades are available. Needed to replace some bad board on the back of my garage and wanted something light so I could cut while boards were still attached to garage, this saw worked great! Injuries can occur if the operator’s hands slip as the stock is being fed into the saw or the hands are too close to the blade. The motor’s arbor should have a brake to stop the saw from continuing after it has been shut off. Hands should never be placed in the cut line and both should remain in contact with the stock, table or push stick at all times when blade is turning. The blade under the table and the power transmission apparatus should be enclosed or situated in such a way to prevent operator contact. For ripsaws a spreader should be used to prevent materials from squeezing the blade or kicking back.
This section covers the major hazards associated with saws and other tolls used in finishing wood stock. In a hand feed lathe the stock rotates rapidly while the operator applies a simple point tool to the wood. The hazards associated with lathes are contact with rotating parts at the point of operation. For automatic lathes with rotating knives a metal shield or hood that completely covers the knives and stock except at the contact points must be in place when the machine is in operation.
In order to lessen the potential of kickback double-spindle shapers shall have starting and stopping device for ach spindle. The most common accident results when the operator attempts to hand hold the stock while drilling. Power transmission components should be enclosed for machines that have adjustable belt drives.
Routers are used for cutting and shaping decorative pieces, making frame and panel doors and milling mouldings.
Inadvertent conduct with the cutting head when handling stock or removing scrap from the table is the most likely cause of injuries. Tenoning machines use cutter heads or saw blades to cut projections (tenons) on pieces of stock. For stationary machines guarding is utilized to prevent operator contact with the cutter head or saw blade. To lessen the possibility of operator contact with the boring bit or mortising chain a number of guards are used.
Routers are used for cutting and shaping, making frame and panel doors and milling mouldings. One of the most common accidents occurs when the operator attempts to hand hold stock while drilling. Injuries can occur if the operator’s hands slip while cutting stock or if they are in the line of cutting.
Path controls involve isolating or reducing noise intensity before it reaches personnel ears. Hand help and stationary tools that transmit vibration through a work piece can cause problems.
Storage and segregation are also vital elements of reducing the possibility of fire and explosion.
Finishing operations present a wide range of health and safety hazards due primarily to the volume and physical properties of the chemicals involved. Engineering controls are the preferred method of eliminating exposures to hazardous contaminants or conditions.
Failure to provide employees and users with information and training related to hazardous chemicals is one of the most frequently cited regulatory violations. Personal protective equipment (PPE) includes respiratory equipment, gloves, boots, safety glasses, coveralls and other clothing or equipment that may be necessary to protect users. While there may only be a few types of circular saws to choose from each is able to cut a wide variety of materials. When considering the purchase of a new circular saw you need to determine your needs and specifications.
Make note of and use this review the next you are faced with purchasing a new circular saw.

The guide appears to be optimized for flooring and other materials that approach its maximum cutting capacity, but it works just fine with thinner workpieces. The kit will include 3 blades for cutting laminate, ceramic, and metal materials, and additional blade types will be available separately.
And, to be satisfied with performance of a tool, the user needs to be aware of the tools comfort range and have more general purpose tools available to do different scopes of projects. I have found that local Sears stores do occasionally carry products that the online store has run out of or doesn’t stock. DIYTrade accepts no responsibility whatsoever in respect of such content.To report fraudulent or illegal content, please click here. There are blades, cutting edges, and shapers which have no more respect for flesh than for wood. The guard must adjust to the thickness of the material being cut and remain in contact with it. If a brake is not practical the operator should remain at the station until the blade stops turning. Anti-kickback fingers should be used to hold the stock down in the event that the saw kicks back the stock.
The operator passes stock over a cylindrical multiple knife cutter head while keeping the stock flush against a guide.
For hand fed jointers with a horizontal cutting head the head should be enclosed with an automatic guard that exposes the cutter head only when the stock is being fed.
The blade runs on a driver and idle pulley and through a work table when stock is manually fed.

They have small thin blades that are held in upper and lower chucks that keep the blade tight.
The operator holds the tool on the tool rest and advances it along the length of the rest to shape the stock. Hands, clothing, or jewelry may be caught on the rotating parts and pulled into the machine. For manual lathes cover the cutter heads as completely as possible with the shield or hood.
Cutting occurs by hand feeding stock against a vertical rotating cutter mounted on a spindle.
Templates and jigs should be used to distance the operator’s hands from the point of operation.
When the drill enters or passes through stock it can catch and twist the stock which could result in an uncontrolled rotating piece of wood. Automatic and high production machines should use barricades or enclosures to separate the operator from the drilling machine. Routers have spindles that spin variously shaped small diameter cutting tools at high speeds. Each tenon can be inserted into a cavity (mortise) or another piece of wood to form a mortise and tenon joint. Feed chains and sprockets shall be enclosed except for the portion of the chain conveying stock.
The boring bits should be enclosed with a guard that covers the bit and chuck above the material being worked. Typically handheld tools are not as inherently dangerous as larger stationary tools of the same type. The moving parts of the sander should be enclosed to prevent fingers from coming into contact with nip points. Routers have spindles that turn variously shaped small diameter cutting tools at high speeds. Contact with the irritant compounds in wood sap can cause dermatitis and other allergic reactions. All noise sources within a piece of equipment as well as the ways in which the noise is transmitted should be identified. Vibration isolators or dampening techniques on equipment offer the best effective protection. This includes the motor, casing, legs, frame, and lights that may be mounted on the machine.
Workers may be injured at the point of operation, drawn into moving part, electrocuted, or suffer crushing injuries. Flammable materials such as paint, finishes, adhesives, and solvents should be stored in proper primary and approved secondary containers.
About 25% of the accidents reported in industry each year are associated with the manual handling and assembly of stock and production wood. These materials can pose significant fire and explosion hazards if used in large quantities, in unventilated or enclosed areas or in processes such as spray finishing which can create large airborne concentrations. This robust saw design makes the worm-drive a traditional favorite among many professional carpenters and homebuilders. These types of circular saws are popular on many construction sites and are the overwhelming choice of homeowners and DIY’ers.
Craftsman has released a new multi-material-cutting version of the mini circular saw, and it comes complete with a convenient miter track. The major area of concern related to the assembly of production material is related to ergonomics.
The lower half should be guarded with a self adjusting, floating guard that automatically adjust to the thickness of the stock. The guard must automatically adjust to cover the unused portion of the head and must remain in contact with the material at all times.
Engineering controls and work practices for minimizing exposure to these hazards are outlined.
A self adjusting guard should be used for the portion of the blade between the sliding guide and the ripper saw so it raises and lowers with the guide.
In an automatic feed lathe the stock is mounted on a carriage and is moved into contact with multiple knife cutter head that runs the length of the stock. The hazard is greater with hand fed lathes because the operator is in close proximity to the rotating stock and the cutting tool.
For lathes used for turning long stock; long stock guards should be present which would prevent the stock from being thrown from the machine should the stock come loose. Knives must be balanced, properly fitted, and precision ground to minimize the possibility of being flung from the cutter head.
The cutting tool is held in a collet chuck and protrudes through a flat, smooth bace that slides on the surface of the wood. However potential hazards related to handheld tools do exist and cause more injuries than their larger stationary cousins. The bit is made of steel or carbide.   It is held in a collet chuck and protrudes through a flat smooth base that slides on the surface of the work. If an air hose greater than ? inch in diameter is used a safety excess flow valve should be installed at the source of the air supply to reduce pressure in the event of hose failure.
Some species of hardwood such as oak, mahogany, beech, walnut, birch, elm, and ash have been reported to cause nasal cancer. For local exhaust ventilation systems to provide protection they must be properly maintained. Sources generally include motors, gears, belts, pulleys, points of operation, and any moving parts.
Maintenance involves lubricating and cleaning, replacing worn parts, maintaining proper belt tension, bolt torque, and properly balanced pulleys, blades, and rotating parts.
Operations may be segregated to limit the number of individuals exposed to excessive noise. This includes identifying power sources, and the correct procedure for shutting down, testing, and re-energizing the equipment.
They also have ignition sources such as electrical wiring, electrical motors, sparking tools, cutting and welding operations. Combustible and flammable materials such as wood stock and chemicals should be segregated from each other and ignition sources.
Adequate ventilation should be provided for all coating and gluing processes; which includes spraying, rolling, brushing, automated coating processes and dip coating.

Engineering methods such as ventilation are the first step to control exposures and limit hazards. Keep the intended applications of your new saw in mind as you evaluate the benefits of each type. The motor on a worm-drive saw is located parallel to the blade, delivering enough torque to cut through wet lumber and concrete over and over without fail. The motor on a sidewinder is perpendicular to the blade, allowing the saw to be lighter and easier to handle.
Not only are lacerations and amputations and eye injuries of concern in woodworking shops but also wood dust and finishing chemicals.
The hood should show the direction of blade rotation so stock will be in the correct direction.
An operator’s hands can come into contact with the point of operation while adjusting the blades. Barriers shall be at the loading and unloading sides to keep hands out of the point of operation.
The operator is required to hand feed and manipulate the stock against the blade to saw along the line. Drum and disc sanders should be enclosed with guards except for the portion of the drum above the table. When ripping, a spreader should be used to prevent material from squeezing the blade or kicking back during ripping. Source controls provide the most effective means of noise reduction and are therefore the preferred methodology. The speed of operation of the equipment should be as slow as possible which is consistent with product quantity and quality goals. Determining the correct type and quantity of dampening material to use for a particular machine is a complicated process and should be done by a safety professional.
Preventing the buildup of sawdust is one of the key elements for controlling fire and explosion hazards. Tasks that are prone to fire and explosion hazards such as spray painting, welding and cutting should be separated from other work. The most common solvents are toluene, xylene, methyl ethyl ketone, methyl isobutyl ketone and methanol. Some of the components may be carcinogenic and may also cause dermatitis and sensitization. Safety data sheets provide information on the chemical constituents that make up a material.
These light-weight, portable, and easy to use hand-held saws allow crosscuts, ripping, beveling and even plunge cuts. If you do plan to use your circular saw for heavy-duty cutting but don’t want the extra weight of a worm-drive saw, sidewinders with helical gearing deliver increased torque. These guidelines are not all inclusive but rather serve to provide a framework for shop safety.
Issues associated with wood dust, noise, electricity and machine maintenance are addressed separate from each section. An adjustable stop should be installed to limit forward travel distance of the blade during repeat cuts. They may also be pinched between the stock and rollers if the feed system isn’t properly guarded. Guards shall be in place to prevent clothing, hair, and hands from being caught by and pulled into the automatic feed mechanism.
The stock must be kept flat on the work table and the operator must exert the correct cutting pressure. The major safety hazard associated with belt sanders is that operators may catch their hand, clothing, or jewelry in the in running rolls. The guard can consist of a protective cover at the rear side of the wheel and a hinged cover around the wheel periphery. Hand-arm vibration syndrome (HAVS) is a more advanced condition that may affect the entire hand or arm. The frequency emitted by the machine, the vibration reduction level desired and the weight and size of the machine are factors. All of the assembly process should be studied to determine if certain processes can be made less stressful on the joints and musculoskeletal frame. Manufacturers must provide safety data sheets and these shall be available to employees and users. If you are not concerned about having all that power, you may appreciate a saw that is lighter to hold and carry. All of these solvents have short term effects such as irritation of the eyes, nose and throat, headaches, dizziness, confusion, fatigue and nausea. For versatile head jointers the cutter head should be completely enclosed except for the slot to apply the stock for jointing.
As the disease progresses a person’s experiences more frequent and severe attacks of numbness and pain and it may become difficult to use their hands.
All exposed personnel should be trained regarding the hazards of working with vibrating tools. Long term effects include damage to the lungs, liver, kidneys, reproductive and central nervous systems. Excessive air pressure decreases efficiency and may cause a backlash of vapors and over spraying into adjacent areas.
Training should include instruction regarding sources of vibration, early signs and symptoms of HAVS and ways of minimizing vibration exposure. Periodically the entire work shop should be cleaned to remove dust that will accumulate in out of the way areas. Dirty air filters decrease air flow in the booth and must be cleaned or replaced periodically. An emergency stop should be within reach of the operator working in the normal operating position.
