RUKO SPB-DIN338-12.7mm-HSSCo kierrepora, 12,7 mm, HSS-Co 5%, DIN 338, split point, 135°

Twist drill bit with 12.7 mm diameter, manufactured from HSS-Co 5% cobalt alloy steel for high heat and wear resistance. The split point tip and 135° point angle provide self-centering and reduced thrust, making it ideal for drilling stainless steel, alloyed and non-alloyed steel, cast iron, non-ferrous metals, and plastics with tensile strength up to 1100 N/mm².

Advantages

Ground from solid with bright finish, this drill bit offers precise hole quality and long tool life. The cobalt alloy withstands high temperatures, while the split point eliminates walking and reduces cutting forces.

Suitable for

• Stainless steel
• Alloyed and non-alloyed steel
• Cast iron
• Non-ferrous metals
• Plastics
