Drill bit for metal GRAPHITE 11.0 mm hex shank (MPN 54T719)

GRAPHITE metal drill bit with an 11.0 mm diameter and hex shank is designed for creating precise holes in a variety of metal materials. The bit combines a robust cutting geometry with a hardened body to withstand the stresses of general metalworking tasks. Its hexagonal shank provides reliable engagement in chucks and quick-change adapters, reducing slip during drilling and enabling fast bit changes on compatible electric and cordless drills.

Advantages

The drill bit offers stable torque transfer thanks to its hex shank, improving control and reducing the risk of cam‑out. Engineered cutting edges and a durable heat-treated body extend service life under normal workshop conditions. The 11.0 mm diameter meets common hole-size requirements for fastening and fabrication, while compatibility with standard hex‑accepting drill chucks and adapters ensures straightforward use with portable and bench drills.

Suitable for

• Drilling holes in mild steel, sheet metal, and other ferrous materials
• Installation of bolts, rivets and threaded inserts
• General metal fabrication and repair tasks
• Portable drilling with electric or cordless drills that accept hex shanks

Key specifications

• Cutting diameter: 11.0 mm
• Shank type: hexagonal shank for secure chuck engagement
• Material: hardened high-speed steel or equivalent metalworking grade
• Intended use: drilling in metal
• Compatibility: suitable for drills and adapters that accept hex shanks

How to use

Fit the hex shank securely into a compatible drill chuck or quick-change adapter, ensuring the bit is seated fully and tightened. Mark the drilling point on the workpiece and, if needed, use a center punch to prevent walking. Start drilling at low speed to establish the hole, then increase speed and apply steady pressure appropriate to the material. Use cutting fluid or lubricant when drilling thicker or harder metals to reduce heat and prolong bit life. Withdraw the bit periodically to clear chips from the hole.

Usage recommendations

Wear appropriate eye and hand protection when drilling. Match drill speed and feed to the metal type and thickness: lower speeds for harder steels, higher speeds for softer metals. Replace the bit if excessive wear, chipping, or loss of cutting performance is observed to maintain hole quality and operator safety.
