The HSS CHEMITOOL drill is made entirely of high-speed steel, with 5% cobalt to increase strength in metals with a hardness up to 1200N/mm2, according to DIN 338.
The main characteristic of this metal spiral drill bit its drilling, which can be used for widening or countersinking thanks to its 135º attack angle.
