Drill bits Dedra WM02557 — 2.5 mm x 57 mm, set of 2, for metal

Set of two Dedra WM02557 twist drill bits with a 2.5 mm cutting diameter and 57 mm overall length, designed for drilling metal. The bits feature high-precision shank and tip geometry to ensure accurate hole placement and steady cutting when used in handheld drills and drill presses. Intended for general metalworking tasks such as creating pilot holes, drilling thin sheet metal and light fabrication work.

Advantages

These Dedra metal drill bits offer consistent cutting performance and dimensional accuracy thanks to their precise tip geometry and straight shank. The 2.5 mm diameter is well-suited to pilot drilling and installation of small fasteners, while the 57 mm length provides adequate reach for most thin to moderate thickness metalwork. Supplied as a set of two, the package gives a quick replacement option to reduce downtime during repetitive tasks.

Suitable for

• Creating pilot holes in steel, iron and non-ferrous sheet metal
• Drilling thin plates and brackets
• Light fabrication and workshop maintenance
• Use with handheld electric drills and drill presses

Key specifications

• Cutting diameter: 2.5 mm
• Overall length: 57 mm
• Material compatibility: metal (steel, iron, non-ferrous metal sheets)
• Quantity in set: 2 pieces
• Shank type: straight shank suitable for standard drill chucks

How to use

Secure the appropriate drill bit in the drill chuck, ensuring it is tightly clamped and correctly centered. Mark the drilling position on the metal surface and, if required, use a center punch to prevent bit wandering. Apply cutting fluid for improved lubrication and cooling when drilling harder metals. Start at low to medium speed to establish the hole, then adjust speed according to material thickness. Withdraw the bit periodically to clear chips and prevent clogging.

Usage recommendations

For best results when drilling metal, use cutting fluid and firm, steady pressure; avoid excessive feed force. For thin sheet metal, a backing support can reduce burrs and deformation. Replace the bit if signs of wear or chipping appear to maintain hole quality and safe operation.
