In this part of our battery drills review series, we have a look the inside of a professional cordless drill. Perfect power selection with this 4-step mechanical gear settings on a Protool battery drill. But if the battery drill does already come with a variable speed switch - why do you need any mechanical gear ? Now assuming you would have the same 18 V battery drill, but with a 2-step mechanical gear. When it comes to the durability of any power tool, some simple areas of serviceability need to be examined. In motor maintenance is where you can find an exceptional difference between a professional battery drill and a battery drill for the do-it-yourselfer. The store is the opportunity to hold a professional cordless drill in your hand time where you can check the ease with which you can replace worn parts. The final area to look at as far as housing of a battery drill is concerned is its overall ergonomics and handling.
A very good example is Makita's recent change on the holding angle of its larger cordless drills.
Additionally its good to see how Makita expanded the "rubber" coating (usually called softgrip ) over to the front part of the handle. Since we covered key parts of battery drills motor, gear, serviceability and ergonomics, lets have a detailed analysis of cordless drill batteries and what type of battery you need to look for when you buy your next drill.

The current model, which Ward made with the help of machinist Jon Kroeker, requires special wheels but has a drill assembly that’s easily detachable for skaters who want to look normal. Any variable speed regulator, such as electronic switches, do loose power while changing speed. Before you decide which brand offers the best battery drills for your needs, you definitely want to have a look at how easy it will be to get spare parts in case you need them. The DIY enthusiast should ask how easy it will be to change the carbon brushes when required. Most professional battery drills such as Bosch or Makita even allow you to change carbon brushes quickly without opening the entire power tool. The picture left shows how Makita changed the angle of the handle (drill to the right is my years-old "dirty" cordless drill). Therefore the best way to judge cordless drill reviews and test if you like any battery drill is to simply take it in your hand and and drive a few screws into a piece of wood.

Ward is the inventor of the KRANX Powerstik, a conversion kit that propels a skateboard on the power of a Black & Decker (or swap in your favorite brand). Depending on the power tool’s capability, it can speed along at up to 14 mph on three miles of flat ground, making the rider look like he or she is beating a hasty get-away from a Home Depot robbery.
In fact a variable speed switch reduces or raises the voltage through the motor as it changes the motors speed and its power.

If you run your drill now at this speed, the battery drill motor would run at full load giving you maximum power and torque . Simple things like replacement batteries, a new switch or carbon brushes may make a big difference.
It is here that your low cost - cheap battery drill models - can fail and force you to replace the entire motor. Unfortunately ergonomics and handling makes this the one item that makes it rather difficult to buy your first cordless drill.

He decided he wanted an electric skateboard while jogging (not sure if there’s a connection there), but not one that actually required him to buy a new board. Depending on the voltage of the battery drill first gears usually run around 400 RPM (no load speed) while second gear is set to approx.
This enables the cordless drill motor to operate at variable power providing appropriate torque. This is the difficulty with a fully encapsulated motor that is found on most low-end drills.
Battery drill manufacturers constantly change and improve the ergonomics and design, sometimes with major implications regarding how you work with and hold the drill.
Obviously you would have only 25% of the torque ( simplified example since the switch itself "consumes" energy ).
