Drill bits Dedra WM03570, 3.5 mm diameter, 70 mm length, metal, pack of 2

Dedra WM03570 drill bits set contains two twist drill bits with a 3.5 mm cutting diameter and a 70 mm overall length designed specifically for drilling metal. These bits fit standard drill chucks and are intended for producing straight, accurate holes in thin to medium metal sheets and components used in maintenance, metalworking and assembly tasks.

Advantages

The set provides two identical metal-working bits for repetitive or backup use, reducing downtime during projects. The 3.5 mm diameter offers a common, versatile hole size for fasteners and fittings, while the 70 mm overall length allows adequate reach through thin panels or when using drill holders. Compatibility with standard chucks and the twist-drill geometry promote stable drilling, consistent hole quality and straightforward replacement when wear occurs.

Suitable for

• Drilling holes in thin to medium metal sheets
• Maintenance and repair tasks on metal components
• Assembly of fittings and fasteners requiring 3.5 mm holes
• General metalworking projects in workshops or on-site

Key specifications

• Cutting diameter: 3.5 mm
• Overall length: 70 mm
• Material suitability: metal
• Quantity in pack: 2 pieces
• Compatibility: standard drill chucks

How to use

Secure the chosen Dedra WM03570 drill bit in a compatible drill chuck, ensuring the bit is centered and tightened. Mark the drilling position on the metal surface and use appropriate clamping to prevent movement. Start drilling at a low speed to establish the hole, apply steady moderate pressure and increase speed as the bit cuts. Use cutting fluid or lubricant to reduce heat and extend bit life when working with thicker or harder metals. After drilling, clear chips from the hole and inspect for burrs; deburr as necessary for a clean finish.

Usage recommendations

Use suitable personal protective equipment (safety glasses and gloves), clamp workpieces securely, and employ cutting fluid for prolonged bit life. Replace bits when wear or dulling affects hole accuracy.
