Drill bit for metal GRAPHITE Hex 3.0 mm, set of 2

GRAPHITE Drill bit for metal Hex 3.0 mm, set of 2 is a pair of twist drill bits designed for drilling 3.0 mm holes in metal. Each bit features a hexagonal shank for secure seating in hex-compatible chucks and bit holders, providing quick changes and reduced slippage during light metalworking, fabrication, repairs, and DIY tasks. The set contains two identical bits to ensure a spare is available for continued work or faster changeover.

Advantages

The hex shank design improves grip in quick-change chucks and bit holders, reducing cam-out and bit rotation. The 3.0 mm diameter is suitable for small through-holes and pilot holes in various metal sheets and components. Supplied as a set of two, the product offers convenience and continuity on the job. The bits are intended for use with standard drilling speeds and typical metalworking practices.

Suitable for

• Drilling 3.0 mm holes in thin metal sheets and plates
• Pilot holes for screws and rivets in metalworking
• Light fabrication and repair tasks
• DIY projects requiring a compact hex shank for quick-change holders

Key specifications

• Tip diameter: 3.0 mm
• Shank type: hexagonal shank for quick-change chucks and bit holders
• Quantity in set: 2 pieces
• Intended material: metal (sheets, plates, light structural components)
• Tool type: twist drill bit for metal

How to use

Install the hex shank into a compatible hex chuck or bit holder and secure it firmly before starting. Select a drilling speed appropriate for the metal being worked—lower speeds for harder metals and higher speeds for softer metals—and apply steady pressure without forcing the bit. Use cutting fluid or coolant when drilling harder metals or when prolonged drilling is required to reduce heat and extend bit life. Withdraw the bit occasionally to clear chips and prevent clogging.

Usage recommendations

For best results, use appropriate personal protective equipment, clamp workpieces securely, and match drilling speed and coolant use to the metal type. Keep a spare bit from the set ready to minimise downtime if a bit becomes blunt or damaged.
