Drill bit set GRAPHITE Hex shank for metal 6.5 mm, 2 pcs

Two-piece GRAPHITE drill bit set with a 6.5 mm cutting diameter and hexagonal shank for drilling metal workpieces. These bits are made for straight, reliable hole-making in steel and other metals and are compatible with hex chucks and quick-change holders. The compact set is suitable for use in hand drills and impact drivers that accept hex shanks, offering a practical option for metal fabrication, maintenance and repair tasks that require precise hole sizes.

Advantages

The hex shank provides fast, secure insertion into hex chucks and quick-change holders, reducing slippage during drilling. A consistent 6.5 mm cutting diameter ensures uniform hole size across repeated operations. Supplied as a two-piece set, it allows immediate replacement of a worn bit without interrupting work and supports mobile tool setups. The design is focused on straight drilling performance in metal, giving predictable chip evacuation and stable cutting action.

Suitable for

• Drilling through steel, iron and non-ferrous metal sheets
• On-site maintenance and repair work with portable drills
• Metal fabrication and assembly tasks requiring precise 6.5 mm holes
• Quick-change workflows using hex chucks or holders

Key specifications

• Cutting diameter: 6.5 mm
• Quantity in set: 2 pieces
• Shank type: hexagonal shank for secure fitment
• Intended material: metal workpieces (steel, iron, non-ferrous metals)
• Compatible tool types: hand drills and impact drivers accepting hex shanks

How to use

Secure the selected drill bit into the hex chuck or quick-change holder ensuring it is fully seated. Mark and centre the drilling point on the metal surface, use a centre punch if necessary to prevent walking, and clamp the workpiece to avoid movement. Start drilling at low speed to establish the hole, apply steady pressure and moderate speed appropriate for the material hardness, and increase coolant or cutting fluid use when required to extend bit life. After drilling, clear chips from the hole and inspect the bit for wear before continuing.

Usage recommendations

Use cutting fluid for drilling thicker or harder metals, maintain moderate speeds to avoid overheating, and replace bits from the set when wear degrades hole quality to maintain consistent 6.5 mm diameters.
