Special Features

M35 HSSCO High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.
Black and gold polished treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge.
135-Degree split point for accurate centering and fast penetration and round shanks allow use with a wide variety of toolholding systems.
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Ideal for drilling in cast iron, zinc alloy, copper, stainless steel and so on.
