Drill bit GRAPHITE 57H130 titanium-coated cylindrical for metal 4.8 mm
GRAPHITE 57H130 titanium-coated cylindrical drill bit for metal, diameter 4.8 mm, is designed for precise drilling in a range of ferrous and non-ferrous metals. The cylindrical shank fits standard chucks of hand drills and drill presses, while the titanium coating provides increased surface hardness and reduced friction during cutting. This tool is suitable for general metalworking, maintenance and installation tasks that require clean, accurate holes with extended tool life.
The titanium coating improves wear resistance and heat dissipation, resulting in longer cutting performance compared with uncoated high-speed steel bits. A precise flute geometry promotes efficient chip evacuation and cleaner hole walls. The cylindrical shank offers stable clamping in most drill chucks and allows quick bit changes for workshop and on-site use.
Secure the drill bit in the chuck so the shank is clamped firmly and run the drill at appropriate speed for the metal being worked — lower speeds for harder ferrous materials and higher speeds for softer non‑ferrous metals. Apply steady feed pressure without excessive force and allow the bit to cut rather than forcing it. Use cutting fluid for improved cooling and lubrication when drilling thicker or harder metals. Periodically clear chips from the hole to avoid clogging and overheating.
For best results, select drill speeds and cutting fluid according to the metal type: slower RPM and coolant for stainless steel or hardened materials; moderate RPM for carbon steel; higher RPM for aluminium. Inspect the coating regularly and replace the bit when wear or chipping affects hole quality.
