## Summary description

Cylindrical shank drill bit by GRAPHITE, model 57H148, designed for drilling metal. The 8.5 mm diameter carbide blank features a titanium coating to increase surface hardness and reduce wear. Suitable for use with drill presses and hand drills on mild and hardened metals for metalworking, fabrication, maintenance, and repair tasks.

## Long description

GRAPHITE drill bit 57H148 is a cylindrical shank metalworking drill with an 8.5 mm diameter and a titanium-coated cutting surface. Intended for drilling a range of ferrous and non-ferrous metals, the tool combines a solid carbide blank with a thin titanium coating to improve surface hardness and reduce abrasive wear during repeated use. The cylindrical shank fits standard chucks on hand drills and drill presses and provides stable rotation for general metal fabrication, maintenance and repair tasks.
Advantages
The titanium coating increases surface hardness and helps extend the service life of the drill bit compared with uncoated bits when working on abrasive or slightly hardened metals. The carbide blank maintains cutting edge strength and heat resistance during intermittent drilling operations. The cylindrical shank offers compatibility with a wide range of chucks and provides concentric rotation for accurate holemaking. Overall design balances durability and straightforward use for workshop and field applications.
Suitable for
 Drilling holes in mild steel and non-ferrous metals
 Light to medium fabrication and assembly work
 Maintenance and repair tasks requiring repeatable hole sizes
 Use with hand drills and drill presses
Key specifications
 Diameter: 8.5 mm
 Shank type: cylindrical
 Material of blank: carbide
 Coating: titanium
 Application: metal drilling
How to use
Secure the drill bit in a compatible chuck, ensuring the cylindrical shank is clamped evenly and concentrically. Select an appropriate rotational speed and feed rate according to the metal type and thickness—lower speeds for harder or thicker materials and higher speeds for softer metals. Use cutting fluid or coolant when drilling ferrous metals to reduce heat and extend tool life. Apply steady pressure, allowing the cutting edges to remove material without forcing the bit. Withdraw occasionally to clear chips and maintain consistent cutting.
Usage recommendations
For best results, pre-drill pilot holes for large diameters or deep holes, maintain proper coolant flow during continuous drilling, and replace the bit when wear noticeably affects hole quality. Store in a dry place and protect the coated surface from impact to preserve the titanium layer.
