## Summary description

Cylindrical metal drill bit GRAPHITE 57H126 with titanium coating, diameter 4.2 mm. Designed for drilling steel and other metals, it offers enhanced wear resistance and longer tool life compared with uncoated bits. Suitable for hand drills and drill presses for metalworking, maintenance and assembly tasks requiring precise 4.2 mm holes.

## Long description

GRAPHITE 57H126 titanium-coated cylindrical drill bit for metal, diameter 4.2 mm, is designed for drilling steel and other metallic materials. The titanium coating increases surface hardness and reduces friction between the cutting edges and the workpiece, which improves wear resistance and extends tool life compared with uncoated bits. The cylindrical shank fits standard drill chucks and is suitable for use in hand-held drills and drill presses for metalworking, maintenance and assembly tasks that require precise 4.2 mm holes.
Advantages
The titanium coating on this GRAPHITE drill bit provides improved wear resistance and reduced heat buildup during drilling, helping to maintain cutting performance over repeated use. The cylindrical shank ensures stable clamping in standard chucks, while the 4.2 mm diameter delivers consistent hole size for drilling operations that demand precision. The bit is manufactured for metalworking applications and balances cutting durability with straightforward handling in common drilling tools.
Suitable for
Drilling holes in steel and non-ferrous metals
Maintenance and repair tasks requiring 4.2 mm holes
Metal fabrication and assembly work
Use in hand drills and bench drill presses
Key specifications
Type: cylindrical-shank twist drill bit for metal
Diameter: 4.2 mm
Coating: titanium (titanium nitride or similar titanium-based coating)
Material application: steel and other metals
Shank style: straight/cylindrical shank for standard chucks
How to use
Secure the drill bit in the chuck of a hand drill or drill press, ensuring the shank is clamped firmly and concentric to the spindle. Select an appropriate drilling speed for the material being worked—lower speeds for harder steels, higher speeds for softer metals—and apply steady, moderate feed pressure. Use cutting fluid or lubricant when drilling steel to reduce heat and prolong tool life. After drilling, back the drill out while the spindle is still turning to clear chips and prevent bit binding.
Usage recommendations
For best results, pre-mark and center-punch hole locations in metal to prevent bit wandering, use recommended cutting speeds and cooling lubricant for the material, and inspect the bit for wear before precision tasks. Replace the bit when cutting edges become dull or when hole accuracy is compromised.
