HSS drill bits are characterized by high flexibility, obtained as a result of appropriate heat treatment.
Particularly with drills below 6mm in diameter, the risk of drill breakage is lower.
The chip groove is covered with an oxide layer which ensures faster chip evacuation. The reinforced and durable core and the increased hardness in the work area guarantee a longer service life.
Made of high-quality steel with very high strength, resistant to torsional stresses.
