## Summary description

GRAPHITE Titanium Metal drill bit 6 mm (model 57H138) is designed for drilling metal. The bit features a titanium coating for increased surface hardness and wear resistance, a 6 mm diameter for medium holes, and a standard shank for use in handheld drills and drill presses. Suitable for workshop and repair tasks requiring precise metal drilling.

## Long description

GRAPHITE drill bit Titanium Metal 6 mm (model 57H138) is a solid twist drill designed specifically for drilling through various metal materials. The 6 mm diameter offers a balance between precision and material removal rate, while the titanium coating increases surface hardness and resistance to wear during repeated use. The straight, standard shank fits common handheld drills and drill presses, making the bit suitable for workshop and repair environments where reliable metal drilling is required.
Advantages
The titanium coating enhances durability and reduces friction, which helps maintain sharpness of the cutting edges and extends tool life during metal drilling. The 6 mm diameter provides consistent hole size for fastening and assembly tasks. A standard shank ensures compatibility with a wide range of drill chucks, and the twist-drill geometry supports efficient chip evacuation and steady drilling performance in metals.
Suitable for
Drilling holes in steel and other ferrous metals
Creating holes for bolts, rivets, and threaded fasteners
Workshop repair and maintenance tasks
Use with handheld drills and drill presses
Key specifications
Material type: high-speed steel base with titanium surface coating
Diameter: 6 mm
Shank type: straight standard shank compatible with common chucks
Drill geometry: twist drill for general metalworking
Typical applications: metal drilling for fastening, assembly and repair
How to use
Select appropriate rotational speed and feed rate for the metal being drilled to avoid overheating and to preserve the coating. Secure the workpiece firmly in a clamp or vise to prevent movement, and mark the drilling location with a center punch for accurate start. Use cutting fluid or lubricant when drilling harder steels to improve chip evacuation and reduce friction; apply steady pressure and allow the drill bit to do the cutting without excessive force. After use, clean chips from the flutes and store the bit in a dry location.
Usage recommendations
For best results, match drill speed to material hardness (lower RPM for hardened steels, medium to high RPM for softer metals), use light cutting lubricant on tougher alloys, and replace the bit when signs of wear or rounded cutting edges appear. Avoid excessive side load to maintain hole accuracy and prolong tool life.
