Plunge cutting router bits, non wood webelos projects - .

Router mortising is very practical for small shop woodworking because it is efficient, produces great results and uses a highly versatile tool — the router. The plunge router is shown in its highest position in the photo immediately below and in its lowest position in the following photo. The router collet is holding a sharp bit that is spinning at 25,000 RPM with the power of two horses so there is no room for compromise in quality. Shown below is the inner collet piece with several slits that make it flexible to grip bits securely.
The 12-amp Elu router shown above has held up well over the years and is nearly identical to the current big DeWalt model DW625, which has a 15-amp motor. When mortising, the router bit must cut downward like a drill bit and cut laterally like a regular router bit.
In upcoming posts, we’ll look at effective, inexpensive setups for mortising with the router.
Straight plunge router bits by Amana feature outstanding tool longevity, a tendency to stay sharper, mirror like carbide finish, excellent carbide brazing, a broad selection of sizes and most importantly quality of cut. Please choose your router bits carefully as different machines require different shank sizes.
2 flute, carbide tipped with bottom cutter insert for plunge cutting, (except for solid carbide router bits #15450, #17740 and #17750, which do not plunge cut). In this post, we’ll look at the type of router you need for mortising, including some specific recommendations, and the right bits to use.


This type of router differs from a regular fixed-base router in that the motor assembly can move up and down on steel posts while routing. Note that the fixed-base router, of course, has a vertical adjustment mechanism, but this is set before routing and is never used for plunging while routing.
Its slight taper fits into a matching recess in the router’s arbor (the third piece). Though the Bosch lacks this helpful feature, the 1617EVS motor can be used with the optional RA1165 base, which has an excellent micro depth adjuster designed for convenient use in a router table setup.
The DW621 is another excellent, somewhat lighter, dedicated plunge router with integral dust collection, which the 625 lacks.
Upcut spiral bits do both very well and also have the advantage of pulling chips out of the cut much as a drill bit does.
All router bits are carbide-tipped unless noted otherwise as solid carbide or solid carbide insert. Amana router bits cut a variety of materials from wood, plywood, MDF and other wood composites, plastics, and solid surface.
Lines etched into the shank allow you to judge whether the router bit is properly seated in the collet. Includes three Katana® solid micrograin carbide spiral bits that cut fast and smooth with an edge that stays sharp longer. This allows you to plunge the rotating bit downward into the wood, lock that vertical position, then push the router to make the bit cut horizontally.


Though each of these routers has a motor rated at 12 amps (120V), the plunge router is larger because of the plunge mechanism and has more widely spaced handles. Similarly, the Bosch 1617EVSPK is the 1617EVS fixed-base router plus the RA1166 plunge base.
The durability and stiffness of solid carbide make it an excellent material for these bits. The standard carbide-tipped straight bit on the right cuts well laterally but its end does not plunge cut. Several weeks ago I purchased one of the Katana router bits, # 17756 and finally got a chance to use it today. Lacking spiral flutes, it also does not efficiently clear chips while cutting a deep mortise. Straight router bits are the workhorse of any router bit collection and will plane, cut grooves, rabbets, slots and dadoes. Successive passes of plunging plus guided horizontal travel will produce a very clean, accurate mortise.
I kept the hospital wrist band and put it inside the box that the router bits came in and to this day it's still there.
