Description:
Manufactured from M35 steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67 with 5% Cobalt, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit. No center punch is needed—the 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or "wander" Extremely heat resistant; must be used and operated at 1500 RPM or greater for maximum efficiency. Straight shank allows for firmly holding and accurate centering,

hss drill bits metal Application
It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used
extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness).
This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel. At room temperature,
in their generally recommended heat treatment, HSS grades generally display high hardness (above Rockwell hardness 60) and abrasion resistance (generally linked to tungsten and vanadium content often used in HSS) compared with common carbon and tool steels.
