Drill cobalt fi 4,3 Inox

Drill 4.3 mm cobalt HSSE Inox. High quality twist drill bit for professional use. It has a smooth cylindrical shank, special grooves for chip evacuation up the hole and strong cutting edges insensitive to impact and lateral forces. The drill bit is manufactured from modern HSS-E high-speed steel. This is a cobalt steel, whose cutting properties are much higher than the capabilities of drills made of conventional tool steel. The drills we offer are characterized by very high hardness and durability against abrasion, even at very high temperatures. Their blades are resistant to breaking, cracking, chipping and other damage. This makes them suitable for machining alloy steels, stainless steel, heat-resistant and acid-resistant steel, as well as cast steel and cast iron. Drill 4.3mm cobalt is recommended for conventional and CNC machine tools.
