RUKO SPB-DIN338-HSSCo8-TiAlN-Ø7,4mm σπειροειδές τρυπάνι

Twist drill bit with 7.4 mm diameter, manufactured from HSS-Co 8 high-speed steel with TiAlN coating for superior heat and wear resistance. The split point tip provides self-centering for precise drilling without wandering.

Advantages

TiAlN coating reduces friction and heat build-up, extending tool life. Cobalt alloyed steel maintains hardness at elevated temperatures. Split point geometry eliminates the need for center punching and reduces thrust requirements.

Suitable for

• Alloyed and unalloyed steel
• Stainless steel
• Cast iron
• Non-ferrous metals
