Drill bit Dedra WIT04580, 4.5 mm diameter, 80 mm length, for metal, 1 pc

Dedra WIT04580 single drill bit, 4.5 mm diameter and 80 mm overall length, is designed for cutting precise through-holes and pilot holes in steel and other metal workpieces. The bit is supplied as one piece and is compatible with common hand drills and drill presses. Its geometry and dimensions are intended to provide controlled chip evacuation and accurate hole positioning when used at appropriate speeds for metal drilling.

Advantages

This 4.5 mm metal drill bit offers a compact combination of diameter and extended length that allows drilling deeper holes while maintaining straightness. The bit’s design supports consistent cutting performance in metal, delivering repeatable hole diameters and smooth entry. Supplied individually, it is easy to store and replace in tool kits or on a workbench.

Suitable for

• Drilling through-holes in steel plates and metal sheets
• Creating pilot holes for tapping or fastening
• Use in portable hand drills for on-site metalwork
• Use in drill presses for controlled, vertical metal drilling

Key specifications

• Diameter: 4.5 mm
• Overall length: 80 mm
• Intended material: metal (steel and similar alloys)
• Package quantity: 1 piece

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring proper centering and tight clamping. Select an appropriate cutting speed and feed for the metal being drilled; lower speeds are generally recommended for harder steels. Use a cutting lubricant or coolant to reduce heat and improve tool life when drilling thicker or harder metals. Start drilling with light pressure to establish the hole and then apply steady feed until the hole is complete. Back the bit out periodically if long chips accumulate.

Usage recommendations

For best results when drilling metal, use cutting fluid, clamp the workpiece securely, and choose drill speeds suited to the material. Inspect the bit for wear before use and replace it when accuracy or cutting performance declines.
