## Summary description

GRAPHITE metal drill bit, model 57H128, with a 4.5 mm diameter and titanium coating. Designed for drilling metal, it features a cylindrical (straight) shank for use in standard drill chucks. Suitable for workshop and maintenance tasks requiring precise holes in steel, non-ferrous metals and sheet metal where a coated bit improves wear resistance and cutting performance.

## Long description

GRAPHITE metal drill bit model 57H128 with a 4.5 mm diameter and titanium coating is designed for precise drilling in metal. The straight cylindrical shank fits standard drill chucks and makes the bit suitable for use in handheld drills and drill presses. The titanium coating increases surface hardness and reduces wear, helping maintain cutting performance during repetitive metalworking tasks.
Advantages
The titanium coating improves wear resistance and reduces friction, extending tool life compared with uncoated bits. A 4.5 mm cutting diameter provides a balance between hole accuracy and material removal rate for common metalworking tasks. The cylindrical shank ensures stable clamping in standard chucks and simplifies quick bit changes. Ground geometry supports efficient chip evacuation and consistent hole quality in steel, non-ferrous metals and sheet metal.
Suitable for
Drilling holes in steel and stainless steel (with appropriate cutting speed and lubrication)
Piercing and enlarging holes in non-ferrous metals such as aluminum and brass
Working with sheet metal and thin plates
Maintenance and workshop repair tasks requiring 4.5 mm holes
Key specifications
Material: high-speed steel body with titanium surface coating
Diameter: 4.5 mm cutting diameter
Shank type: cylindrical (straight) shank compatible with standard chucks
Coating: titanium coating for enhanced surface hardness and reduced friction
Intended use: metal drilling including steel, non-ferrous metals and sheet metal
How to use
Secure the drill bit in the chuck so the cylindrical shank is clamped firmly and runs true. Select appropriate spindle speed for the workpiece material — lower speeds for stainless steel, medium speeds for carbon steel, and higher speeds for non-ferrous metals like aluminum — and apply cutting fluid or lubricant when drilling harder steels to reduce heat and extend tool life. Start with a pilot mark or center punch on thin or sheet materials to prevent walking, then drill with steady, moderate feed pressure. Clear chips periodically to maintain cutting efficiency.
Usage recommendations
Use the 4.5 mm titanium-coated GRAPHITE drill bit for routine metalwork where improved wear resistance and consistent hole quality are required. Match drill speed and use appropriate lubrication for the specific metal to maximize tool life and achieve accurate holes.
