RUKO SPB-DIN338 10,6 mm έλασης τρυπάνι HSS σπειροειδές

Twist drill bit with a 10.6 mm diameter, roll-forged from high-speed steel for efficient drilling in a wide range of materials. The 118° point angle and right-hand cutting geometry deliver clean, accurate holes in steel, cast iron, non-ferrous metals, plastics, and wood.

Advantages

Roll-forged HSS construction provides high toughness and heat resistance up to 400°C. The black oxide surface treatment reduces friction and improves chip evacuation, while the cylindrical shank ensures secure clamping in standard drill chucks.

Suitable for

• General-purpose drilling in steel and cast iron
• Non-ferrous metals such as aluminium and brass
• Plastics and wood
• Use with corded/cordless drills and drill presses
