Drill bit set Dedra WM04580 — 4.5 mm diameter, 80 mm length, 2 pieces, for metal

Dedra WM04580 drill bit set contains two 4.5 mm diameter, 80 mm long bits designed specifically for drilling metal. These straight-shank bits are intended for use with hand drills and drill drivers on thin to medium-thickness metal sheets and components. The compact two-piece set is suitable for workshop and repair tasks that require precise small-diameter holes in steel, aluminum and other common metal alloys.

Advantages

The set provides a consistent 4.5 mm hole size and extended 80 mm length for reaching through thin panels or through multi-layer assemblies. Delivered as a pair, the bits allow quick replacement when one becomes blunt, reducing downtime during routine jobs. The geometry and cutting edges are optimised for metal, improving hole quality and reducing burr formation compared with general-purpose bits.

Suitable for

• Drilling holes in thin to medium-thickness steel and aluminium sheets
• Creating pilot holes for screws or rivets in metal components
• Workshop maintenance and light repair tasks
• Electrical and HVAC bracket installation where small metal holes are required

Key specifications

• Diameter: 4.5 mm
• Overall length: 80 mm
• Quantity: 2 pieces
• Intended material: metal (thin to medium thickness)
• Shank type: straight shank for standard chucks

How to use

Secure the chosen Dedra 4.5 mm bit in the drill chuck and tighten firmly. Select an appropriate drill speed for the metal type—moderate speeds for steel, higher speeds for aluminium—and apply steady pressure without forcing the bit. Use cutting lubricant or coolant when drilling harder steels to extend bit life and improve cutting performance. After drilling, deburr the hole if necessary to remove sharp edges.

Usage recommendations

For best results, start with a centre punch to prevent bit walking, clamp the workpiece securely, and use a lubricant on harder metals. Replace bits when cutting edges become dull to maintain hole accuracy and avoid overheating.
