Drill Bit GRAPHITE 57H164 cylindrical titanium-coated for metal 12.5 mm

GRAPHITE 57H164 cylindrical titanium-coated drill bit, 12.5 mm diameter, is designed for drilling steel and other metal materials. The straight (cylindrical) shank allows secure clamping in chucks and holders, while the titanium coating improves wear resistance and reduces friction during cutting. This drill bit is intended for workshop, construction and maintenance tasks that require reliable, precise holes in metal components.

Advantages

The titanium coating increases surface hardness and reduces heat buildup, extending tool life compared with uncoated bits. The cylindrical shank ensures accurate centring and stable rotation in standard drill chucks. Precision-ground tip geometry provides consistent chip evacuation and clean hole edges in a variety of ferrous and non-ferrous metals. The 12.5 mm diameter is a common size for pilot and through-holes in metalworking, offering a balance between rigidity and cutting speed.

Suitable for

• Drilling steel plates, bars and profiles
• Creating holes in aluminum and other non-ferrous metals
• Workshop engine and maintenance tasks
• Construction and installation work involving metal fastenings
• Preparation of parts for tapping and fastening

Key specifications

• Diameter: 12.5 mm
• Shank type: cylindrical (straight)
• Coating: titanium (Ti) surface treatment for increased wear resistance
• Material application: suitable for ferrous and many non-ferrous metals
• Tip: precision-ground for improved cutting and chip evacuation

How to use

Secure the drill bit in a compatible chuck designed for cylindrical shanks, ensuring tight clamping and correct alignment. Select an appropriate rotational speed and cutting fluid based on the metal type and thickness to reduce heat and prolong tool life. Start drilling with light pressure to establish the hole, then apply steady feed pressure; withdraw periodically for chip clearance when drilling deep holes. After use, remove chips and lightly clean the coating surface to prevent corrosion and maintain performance.

Usage recommendations

For best results when drilling steel, use moderate speeds and a suitable cutting lubricant. Avoid excessive pressure that can cause rapid wear or bit breakage. Inspect the cutting edges before use and replace the bit when wear reduces drilling accuracy.
