Fein magnetic drills are the most advanced mag drills on the market today with their compact, lightweight and precise engineering. All the components of the Fein KBM 32Q and KBM 50QX are designed and built by Fein to create a unique, low-profile tool that holds better, fits in more places and is more durable and precise, unlike most other mag drills. Fein Magnetic Core Drills are 20% to 40 percent lighter in weight than most conventional core drills, making a Fein drill able to hold power greater. Thanks to its unitized construction, the weight to holding power ratio is up to 50 percent greater than other popular drills. Other features include Fein's Quick-IN tooling system which allows you to instantly change cutters. Besides Fein's Quick-IN annular cutters, most competitive cutters can easily be used with the adapters included with the tool. As with all Fein products, Fein magnetic drills employ advanced motor technology to maximize the power and torque delivered to the drill.
