## Summary description

Cylindrical drill bit GRAPHITE 57H156 with titanium coating, 10.5 mm diameter, designed for drilling metal. Suitable for general metalworking tasks, creating through and blind holes in steel and non-ferrous metals. The titanium layer improves wear resistance and cutting performance; compatible with standard drill chucks for workshop and industrial use.

## Long description

Cylindrical drill bit GRAPHITE 57H156 with a 10.5 mm diameter and titanium coating is designed for drilling metal. It is made for use with standard drill chucks in workshops and industrial environments and is suitable for creating both through and blind holes in steel and non-ferrous metals. The titanium layer increases surface hardness and reduces friction, helping to extend tool life and maintain cutting performance under repeated use.
Advantages
The titanium coating provides improved wear resistance and reduces heat buildup during drilling, which helps preserve cutting geometry and prolong service life. The cylindrical shank fits common chucks for secure clamping and easy changeover. The 10.5 mm diameter offers a balance between hole precision and cutting speed for general metalworking tasks. Manufactured to consistent dimensions, the drill bit ensures repeatable hole sizes and reliable fit for bolts, pins, and other fasteners.
Suitable for
 Drilling through and blind holes in steel and cast iron
 Working with non-ferrous metals such as aluminium, brass and copper
 General workshop and maintenance drilling tasks
 Use in handheld and bench drills with compatible chucks
Key specifications
 Drill type: twist drill bit for metal
 Diameter: 10.5 mm
 Shank type: cylindrical (straight) shank for standard chucks
 Coating: titanium layer for increased hardness and reduced friction
 Material compatibility: steel and non-ferrous metals
 Typical applications: through and blind hole drilling
How to use
Secure the drill bit in a compatible drill chuck, ensuring the shank is clamped straight and tight. Select an appropriate spindle speed and feed rate for the workpiece material—lower speeds for harder steels, higher speeds for softer non-ferrous metals. Use cutting fluid or lubricant when drilling steel to reduce heat and improve chip evacuation. Apply steady axial pressure and avoid excessive side loads; retract occasionally to clear chips when drilling deep holes. After use, clean off any residues and store the bit in a protective holder to preserve the titanium coating.
Usage recommendations
For best results, match drill speed and lubrication to the material: use cutting oil for steels and light lubrication for aluminium. Replace the bit when signs of wear or chipping appear to maintain hole quality and reduce the risk of workpiece damage.
