90° 3-CUTTING-EDGE HSS COUNTERSINKS SELF

Countersinks made of high-speed steel (HSS) with three cutting edges and a 90° angle, compliant with DIN 335-90°. Designed for countersinking operations on steel and other metals, they ensure precise and uniform machining. The three-edge geometry promotes smooth cutting and effective chip evacuation, optimising productivity. The HSS construction provides wear resistance and durability even under demanding conditions. These countersinks are suitable for hole finishing and surface preparation for threading or welding, offering accurate countersink control in professional applications.
