Brute Platinum XL28 mechanics length drills are engineered for high performance. The three-flat shank design ensures a positive grip in both keyless and conventional power tools; while the reduced overall length provides added strength and rigidity. An exclusive combination of premium high speed steel, superior geometry and Champion's unique NOMO (Nitride On Margin Only treatment) maximizes the number of holes per drill. Brute Platinum XL28 drills penetrate faster than cobalt, providing lower fatigue levels to the operator, since less force is required to drill. made in the USA
