Drill bit GRAPHITE 10 mm titanium-coated cylindrical shank for metal (57H154)

GRAPHITE 10 mm titanium-coated drill bit with a cylindrical shank is designed for drilling metal. With a 10 mm cutting diameter and a straight shank, the bit fits standard drill chucks and is suitable for general metalworking tasks including holes in steel, iron and non-ferrous metals. The titanium coating improves wear resistance and helps reduce heat buildup during drilling, extending tool life under typical workshop conditions.

Advantages

The titanium coating provides increased surface hardness and better heat dissipation compared to uncoated bits, which helps maintain cutting performance during continuous use. The cylindrical (straight) shank ensures secure clamping in most hand drills and drill presses. The 10 mm diameter offers a balance between hole size and rigidity, making the bit stable under moderate feed pressures in metalworking applications.

Suitable for

• Drilling holes in steel and cast iron
• Drilling non-ferrous metals such as aluminium and brass
• General workshop and maintenance drilling tasks
• Use with hand drills and drill presses that accept straight shanks

Key specifications

• Cutting diameter: 10 mm
• Shank type: cylindrical (straight) shank suitable for drill chucks
• Coating: titanium coating for improved wear resistance and heat dissipation
• Intended material: metals (steel, iron, non-ferrous metals)

How to use

Clamp the cylindrical shank securely in a compatible drill chuck and set the drill to an appropriate speed for the material being worked; lower speeds are recommended for harder steels and higher speeds for softer non-ferrous metals. Use cutting fluid or lubricant when drilling steel or other ferrous materials to reduce heat and extend tool life. Apply steady, even pressure and clear chips frequently to maintain cutting efficiency and avoid overheating.

Usage recommendations

For best results, select drill speeds according to the metal type and thickness, use a suitable cutting fluid when working with steel, and avoid excessive side loads that can bend the bit. Inspect the bit for wear before use and replace if the cutting edges are chipped or rounded to maintain hole accuracy and safety.
