Drill bit Dedra WM04075 — 4 mm diameter, 75 mm length, for metal, 2 pcs

Dedra WM04075 drill bits, 4 mm diameter and 75 mm overall length, supplied in a set of two pieces. These straight-shank bits are intended for drilling metal and are compatible with handheld electric drills and drill presses. They are sized for creating through-holes and pilot holes in steel and similar ferrous and non-ferrous metals where a precise 4 mm hole is required.

Advantages

These Dedra drill bits offer consistent diameter and straightness for accurate hole placement. The 75 mm overall length provides reach for typical sheet and plate work while maintaining rigidity to reduce wobble. Supplied as a pair, the set ensures a spare bit is available for continuous work or replacement. The straight shank design fits standard drill chucks, ensuring straightforward mounting and reliable power transfer.

Suitable for

• Drilling through-holes in steel sheets and plates
• Creating pilot holes for threaded fasteners in metal
• Light fabrication and repair tasks on ferrous and non-ferrous metals
• Use with handheld drills and drill presses

Key specifications

• Diameter: 4 mm
• Overall length: 75 mm
• Material compatibility: metal (steel and similar metals)
• Shank type: straight shank for standard chucks
• Quantity in pack: 2 pieces

How to use

Secure the workpiece and mark the drilling position. Select an appropriate cutting speed and apply cutting fluid if drilling steel to extend bit life and improve chip evacuation. Insert the straight shank into the drill chuck and tighten securely. Use steady pressure and maintain perpendicular alignment to the work surface for a clean, accurate 4 mm hole. Withdraw the bit periodically when drilling deeper holes to clear chips and cool the cutting edge.

Usage recommendations

For best results when drilling metal, start with a slower spindle speed and increase as appropriate for the material and drill type. Use light, consistent pressure and cooling lubricant for steel to reduce wear and prevent overheating. Replace the bit if signs of dulling or chipping appear to preserve hole quality and safety.
