RUKO SPB-DIN338 14,5mm valssattu spiraalipora

Twist drill bit with 14.5 mm diameter, manufactured from rolled high-speed steel (HSS-R) to DIN 338. The roll-forged process and black oxide finish deliver a robust cutting edge for general-purpose drilling in steel, cast iron, non-ferrous metals, plastics, and wood.

Advantages

Roll-forged HSS-R construction provides high toughness and resistance to breakage. The 118° point angle and tapered core ensure accurate centring and efficient chip removal. Black oxide surface reduces friction and improves wear resistance.

Suitable for

• Steel up to approx. 900 N/mm² tensile strength
• Cast iron
• Non-ferrous metals
• Plastics
• Wood
