1/2 inch HSS Split Point Jobber Length Drill Bit, Qualtech, Dwdsp1/2, Pack of 6

Description

Ideal for production, maintenance or portable drilling jobs. Drill America DWDSP Series General Purpose Split Point Drill Bit is a dependable, general purpose drill designed to perform in a broad range of materials in the iron and steel families. Black oxide surface treatment reduces chip welding and improves chip flow. Round shanks allow use with a wide variety of toolholding systems. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. The 135 degree split point is self-centering and reduces thrust. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Sizes smaller than 1/16 have the 118 standard point. Surface treated with abrasion-resistant black oxide.
