Drill bit for metal GRAPHITE Hex shank 12.0 mm (MPN 54T720)

GRAPHITE metal drill bit with a 12.0 mm cutting diameter and hex shank is designed for drilling accurate holes in various metal materials. The solid construction and cutting geometry allow consistent performance in tasks such as installation, repair and fabrication. The hex shank ensures secure engagement with handheld drills and drill drivers that accept hex quick-change chucks.

Advantages

This drill bit combines a 12.0 mm cutting diameter with a hex shank for firm retention in quick-change chucks, reducing slippage during work. The geometry of the cutting edge supports precise hole creation and stable drilling in metal, while the shaft profile facilitates rapid bit changes in portable and corded drills. The tool is made to meet common metalworking needs and to withstand normal wear encountered in professional and DIY applications.

Suitable for

• Drilling holes in steel and other common metals
• Installation tasks such as mounting brackets and fixtures
• Repair and maintenance work on metal components
• Fabrication and metalworking projects requiring precise holes

Key specifications

• Cutting diameter: 12.0 mm
• Shank type: hex shank compatible with hex quick-change chucks
• Material suitability: designed for metal materials such as steel and similar alloys
• Intended tool compatibility: handheld drills and drill drivers with hex chuck or quick-change adapter

How to use

Secure the drill bit in the drill's hex chuck or quick-change adaptor and ensure it is seated fully to prevent wobble. Mark the drilling position on the metal surface and, if necessary, use a center punch to create a pilot mark. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit condition while applying steady, even pressure. Use cutting fluid or lubricant for harder metals to extend bit life and improve chip evacuation. After drilling, retract the bit while the drill is running briefly to clear chips, then stop and inspect the hole.

Usage recommendations

For best results, use appropriate personal protective equipment, clamp workpieces securely, and select drill speed and lubrication according to the metal type. Replace the bit when wear or chipping reduces drilling accuracy.
