RUKO KEB-HSS-TiAlN Mod.55 12,0mm σπειροειδές τρυπάνι

Twist drill bit with 12.0 mm diameter, ground from solid HSS and coated with TiAlN for high heat and wear resistance. The TiAlN coating reduces friction and allows higher cutting speeds, extending tool life in demanding applications. The cylindrical shank fits standard drill chucks, and the right-hand cutting direction suits conventional drilling machines.

Advantages

TiAlN coating provides high heat resistance and wear resistance, enabling longer tool life and higher productivity. The ground flute geometry ensures precise hole quality and efficient chip evacuation. The 118° point angle is suitable for general-purpose drilling in a variety of materials.

Suitable for

• Steel up to 900 N/mm²
• Cast iron
• Non-ferrous metals
• Plastics
