Feature
High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.
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.
Round shanks allow use with a wide variety of toolholding systems.
Ideal for production, maintenance or portable drilling jobs.

Package Includes:
5pcs x Drill Bits
1pcs x Wrench
