Drill America 21-Piece Heavy Duty Drill Bit Set

The Drill America KFD 21-piece 135-degree split point heavy-duty drill bit set, manufactured from premium-grade High-Speed Steel, comes in a metal case. Killer Force Drills have a heavy-duty 135-degree split point for self-centering and reducing thrust, with a gold and black surface treatment for use in stainless steel and other hard metal drilling.

High-speed steel tools are suitable for most general-purpose applications, offering a combination of hardness and toughness for wear resistance. The black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. The round shanks allow the use of a wide variety of toolholding systems.

When run in a counterclockwise direction (right-hand cut), the spiral-fluted tools evacuate chips up and out of the cut, reducing clogging. The set includes fractional sizes ranging from 1/16" to 3/8" (1/64" increments).
