Drill bit set GRAPHITE Hex 7.5 mm for metal, 2 pieces

Two-piece set of GRAPHITE Hex drill bits sized 7.5 mm designed for drilling metal. These bits have a hexagonal shank that ensures secure engagement in hex chucks and quick-change holders, providing stable rotation and reduced slippage during standard metalworking operations. The set is intended for general fabrication, repair and maintenance tasks where a precise 7.5 mm hole is required in steel and other metal materials.

Advantages

The hex shank design delivers firm grip in compatible chucks and quick-change adapters, improving control and reducing the risk of stripping. Hardened cutting edges and geometry optimized for metal reduce walking and improve hole quality. Supplied as a two-piece set, it provides a backup bit on hand for continuous work and cuts downtime for bit changes. The compact set is easy to store and transport in a toolbox or accessory compartment.

Suitable for

• Drilling 7.5 mm holes in steel and ferrous metals
• General metal fabrication and assembly
• Maintenance and repair tasks on machinery and metal structures
• Use with hex chucks, quick-change holders, and impact drivers supporting hex shanks

Key specifications

• Drill diameter: 7.5 mm
• Quantity in set: 2 pieces
• Shank type: hexagonal shank for secure chuck engagement
• Intended material: metal (steel and similar alloys)
• Typical applications: through-holes and pilot holes in metalworking

How to use

Install the 7.5 mm hex shank into a compatible hex chuck, quick-change holder, or driver designed to accept hex shanks. Secure the bit fully before starting the drill. Use appropriate cutting speed and steady feed pressure for the metal being drilled; for most steel, use moderate speed and apply cutting lubricant to reduce heat build-up and prolong bit life. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

Use suitable personal protective equipment including eye protection and gloves. Match drill speed and lubrication to the metal type, and avoid excessive force to prevent bit breakage. Store the bits dry and protected to maintain cutting performance.
