Drill bit Dedra WM07010 — 7 mm diameter, 109 mm length, for metal, 1 pc

Solid drill bit Dedra WM07010 with a 7 mm diameter and 109 mm overall length, designed specifically for drilling metal. Supplied as a single piece, this straight-shank bit fits standard drill chucks and is intended for general metalworking tasks such as creating holes in sheet metal, brackets, and light steel components. The geometry and dimensions make it suitable for workshop maintenance and occasional professional use where a reliable, single-size metal drill is required.

Advantages

The 7 mm cutting diameter and 109 mm overall length provide a balance between reach and rigidity, reducing wobble during drilling. Manufactured by Dedra, the bit is optimized for cutting metal with consistent hole quality and predictable chip evacuation. The straight shank allows secure clamping in standard drill chucks, and the single-piece supply makes it convenient to keep as a spare or to use in task-specific toolkits.

Suitable for

• Drilling holes in sheet metal
• Making mounting holes in brackets and light steel parts
• Workshop maintenance and repair tasks
• Preparing holes for bolts, rivets, or threaded inserts in thin-to-medium metal

Key specifications

• Cutting diameter: 7 mm
• Overall length: 109 mm
• Shank type: straight shank for standard chucks
• Intended material: metal (suitable for sheet metal and light steel)
• Quantity: 1 piece

How to use

Select appropriate drill speed and lubrication for the metal you are working with, clamp the workpiece securely, and insert the straight shank into the drill chuck ensuring firm tightening. Start drilling with a slow feed to establish the hole then increase speed moderately while applying steady pressure. Use cutting fluid or oil for improved cutting performance and to extend the bit life when working with steel or alloyed metals. After drilling, back the bit out of the hole while the drill is still turning to clear chips and prevent jamming.

Usage recommendations

For best results when drilling metal, use appropriate RPM for a 7 mm twist drill in relation to the material hardness, apply cutting fluid to reduce heat, and avoid excessive lateral forces. Inspect the bit for wear or dulling before use and replace when cutting performance degrades to maintain hole accuracy and safety.
