Drill bit set GRAPHITE hex shank for metal, 3.5 mm, 2 pcs

Two-piece GRAPHITE drill bit set with 3.5 mm cutting diameter and hex shank designed for drilling into metal sheets and similar materials. The set includes two identical bits that fit hex-chuck drivers and impact screwdrivers, offering a compact solution for creating small-diameter holes in metal during workshop or DIY tasks.

Advantages

The hex shank ensures quick and secure bit changes in hex chucks and impact drivers, reducing slippage during drilling. A 3.5 mm cutting diameter provides precise, repeatable hole sizes for fastening and assembly work. The two-piece configuration gives an immediate spare bit for uninterrupted work and extends overall productivity in repair, installation, and fabrication tasks.

Suitable for

• Drilling holes in thin metal sheets and light-gauge steel
• Installation of small fasteners and rivets
• Workshop repairs and maintenance tasks
• DIY projects requiring precise small-diameter metal holes

Key specifications

• Cutting diameter: 3.5 mm
• Shank type: hex shank for secure retention in hex chucks and impact drivers
• Quantity: 2 pieces
• Material suitability: designed for use in metal and similar materials

How to use

Secure the appropriate bit in a compatible hex-chuck driver or impact screwdriver, ensuring the shank is fully seated. Mark the drilling point on the workpiece and, where applicable, clamp the workpiece to prevent movement. Start at low speed to establish the hole, then increase speed as needed while applying steady, moderate pressure. Use cutting lubricant when drilling thicker or harder metal to reduce heat and prolong bit life. Replace the bit with the spare included in the set if wear or dulling occurs.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses and gloves. For best results on thicker metals, use cutting oil and allow periodic breaks to avoid overheating. Verify compatibility of the hex shank with your driver prior to use and avoid excessive side pressure to maintain hole accuracy and bit longevity.
