Drill bit for metal GRAPHITE 13.0 mm hex shank model 54T721

GRAPHITE 13.0 mm metal drill bit with a hex shank, model 54T721, is designed for drilling accurate round holes in ferrous and non-ferrous metals. The hex shank provides secure seating in quick-change chucks and impact drivers, reducing slippage during rotational and percussive use. This drill bit is intended for metalwork tasks in workshops, construction sites and maintenance settings where consistent hole diameter and straightforward tool changes are required.

Advantages

The hex shank ensures stable engagement with chucks and adapters, improving torque transfer and reducing cam-out. The 13.0 mm diameter offers a common size for through-holes and clearance holes in metal assemblies. The cutting geometry is optimized for metal drilling to produce round holes with minimal burrs when used at appropriate speeds and with cutting fluid. Durable material and heat-resistant finishing extend service life under standard working conditions.

Suitable for

• Drilling through sheet metal and metal plates
• Creating clearance holes for bolts and fasteners in metal assemblies
• Workshop and maintenance drilling tasks on ferrous and non-ferrous metals
• Use with quick-change chucks and impact drivers that accept hex shanks

Key specifications

• Drill diameter: 13.0 mm
• Shank type: hex shank for secure chuck engagement
• Application: drilling in ferrous and non-ferrous metals
• Typical compatibility: handheld drills, bench drills and impact drivers with appropriate hex chuck or adapter
• Cutting geometry: designed for metalworking to reduce burr formation

How to use

Secure the drill bit in a compatible chuck or quick-change adapter, ensuring the hex shank is fully seated. Select an appropriate spindle speed for the metal type and thickness — lower speeds for harder ferrous metals, higher speeds for softer non-ferrous alloys — and apply steady feed pressure without excessive force. Use cutting fluid or lubricant for improved chip evacuation and reduced heat when drilling thicker sections or harder materials. Withdraw the bit periodically to clear chips on deep holes and allow the bit to cool if it becomes hot.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and lubricant to the material being drilled, clamp workpieces securely, and avoid side loading to maintain drill bit life and achieve precise, round holes.
