RUKO Broca helicoidal com haste reduzida 14,5 mm HSS-Co

Reduced shank twist drill bit for precision drilling in tough materials, featuring a 14.5 mm diameter and 5% cobalt HSS for high heat resistance. Its 135° split point prevents walking and reduces thrust, while the precision ground flutes ensure efficient chip removal.

Advantages

HSS-Co steel with 5% cobalt maintains hardness at high temperatures, extending tool life in demanding applications. The reduced 10 mm shank allows use in standard drill chucks, while the split point geometry provides accurate centering without a pilot hole.

Suitable for

• Stainless steel
• High-alloy steels
• Cast iron
• Non-ferrous metals
• Plastics
