## Summary description

GRAPHITE drill bit for metal with a 7.5 mm diameter and titanium coating, featuring a cylindrical shank. Designed for drilling steel and other metal materials, the bit provides increased surface hardness and wear resistance from the titanium layer. Suitable for hand drills and drill presses for general metalworking, fabrication, maintenance and repair tasks.

## Long description

GRAPHITE 7.5 mm titanium-coated drill bit with a cylindrical shank is designed for drilling holes in steel and other metal materials. The titanium coating increases surface hardness and wear resistance, extending tool life during general metalworking tasks. The cylindrical shank fits standard chucks on hand drills and drill presses, making this bit suitable for both portable and stationary drilling applications.
Advantages
The titanium coating provides improved wear resistance and reduced friction compared with uncoated high-speed steel bits, resulting in longer service life and more consistent cutting performance. The 7.5 mm diameter offers a common hole size for fabrication and repair work, while the cylindrical shank ensures secure clamping in standard chucks. The geometry and material selection are aimed at offering reliable drilling performance in a variety of ferrous and non-ferrous metals.
Suitable for
 Drilling holes in steel, iron and other ferrous metals
 Drilling in non-ferrous metals such as aluminum and brass
 General metal fabrication and assembly
 Maintenance, repair and workshop use with hand drills or drill presses
Key specifications
 Drill diameter: 7.5 mm
 Coating: titanium
 Shank type: cylindrical (straight) shank for standard chucks
 Intended material: steel and other metals
 Usage: for hand-held drills and drill presses
How to use
Secure the drill bit firmly in the drill chuck, ensuring correct alignment and clamping depth. Select an appropriate rotational speed for the material being drilled—lower speeds for hard steels, higher speeds for softer metals—and apply steady pressure without excessive force. Use cutting fluid or lubricant when drilling hard or thick metal to reduce heat build-up and prolong bit life. Retract periodically for chip clearance on deep holes.
Usage recommendations
For best results, match drill speed and feed to the metal type, use suitable cutting fluid for harder steels, and replace the bit when wear or chipping reduces cutting efficiency. Store bits dry and clean to preserve the titanium coating.
