Drill bit GRAPHITE 13 mm titanium-coated cylindrical shank for metal (57H166)

GRAPHITE 13 mm titanium-coated drill bit with a cylindrical shank designed for drilling metal. The titanium coating increases surface hardness and wear resistance, helping to maintain sharpness when working with steel and similar ferrous materials. The cylindrical shank fits standard chucks on handheld drills and drill presses, making the bit suitable for general metalworking tasks such as creating holes for fasteners, fabrication and maintenance.

Advantages

The titanium coating improves cutting performance and extends tool life compared to uncoated bits when drilling into steel and similar metals. A 13 mm diameter provides a common size for fastening and assembly operations, while the cylindrical shank ensures secure clamping in standard drill chucks. The bit is balanced for use in both handheld drills and drill presses, allowing consistent hole quality across different metalworking setups.

Suitable for

• Drilling holes in mild and medium-hard steels
• Creating holes for bolts, screws and rivets
• Metal fabrication and repair work
• Use with handheld drills and drill presses

Key specifications

• Diameter: 13 mm
• Coating: Titanium
• Shank type: Cylindrical
• Material suitability: Steel and similar ferrous metals
• Intended use: Metal drilling

How to use

Secure the drill bit in the drill chuck so the shank is clamped firmly and runout is minimised. Select an appropriate cutting speed and feed for the metal type and thickness; lower speeds are generally recommended for harder steels. Use cutting fluid or lubricant to reduce heat, improve chip evacuation and prolong tool life. Apply steady pressure without forcing the bit; withdraw periodically for chip removal when drilling deep holes.

Usage recommendations

For best results, use cutting fluid and a drill press where possible to ensure perpendicular holes and consistent speeds. Inspect the bit regularly for wear and replace when the cutting edge becomes dull to avoid workpiece damage and excessive heat buildup.
