Drill bits set Dedra WMT03570 — 10 pcs, 3.5 mm diameter, 70 mm length, for metal

Dedra WMT03570 is a set of ten drill bits specifically designed for metalworking applications. Each bit in the set has a 3.5 mm diameter and a 70 mm overall length, providing a consistent size for repetitive drilling tasks. The set is intended for producing clean 3.5 mm holes in a range of metal materials commonly found in workshops, maintenance and fabrication work.

Advantages

The Dedra WMT03570 set offers uniform diameter and length across all ten pieces, which helps reduce tool change time and ensures consistent hole size. The bits are optimized for metal drilling, providing reliable penetration and predictable cutting performance when used with appropriate speeds and cutting fluids. Having multiple identical bits increases efficiency by providing spares that maintain the same drilling geometry throughout a project.

Suitable for

• Creating 3.5 mm pilot or through-holes in steel and other ferrous metals
• Maintenance and repair drilling where consistent hole diameter is required
• Metal fabrication tasks, jigs and fixtures preparation
• Workshop and professional trade use for repeatable small-diameter holes

Key specifications

• Diameter: 3.5 mm
• Overall length: 70 mm
• Intended material: metal
• Quantity in set: 10 pieces

How to use

Secure the workpiece and mark the drilling point before starting. Clamp the selected 3.5 mm bit in the drill chuck and set the drill to a speed appropriate for the metal being drilled. Apply steady axial pressure and allow the bit to cut without forcing; for thicker or harder metals use intermittent pecking to clear chips. Use cutting fluid or lubricant when recommended for the metal type to extend bit life and improve hole finish. After drilling, deburr the hole edges as needed.

Usage recommendations

Use appropriate drill speeds and cutting fluids for the specific metal to maximize bit life and achieve consistent hole quality; store bits in a protective case to prevent tip damage and maintain accuracy.
