Drill bit set Dedra WM02049 — 2 mm diameter, 49 mm length, 3 pcs, for metal

Dedra WM02049 drill bit set contains three straight-shank bits with a 2 mm cutting diameter and 49 mm overall length, designed specifically for drilling metal. These bits are intended for precision metalworking, maintenance and repair tasks where narrow, accurate holes are required. The bits fit standard drill chucks and are suitable for use in hand drills and drill presses on thin metal sheets and small components.

Advantages

The set includes three identical bits for consistent repeatability and quick replacement during work. The 2 mm diameter provides accurate hole sizing for small fasteners, pilot holes and alignment pins. The 49 mm length offers enough reach for most thin-sheet and component drilling while remaining rigid for reduced wandering. Compatibility with standard chucks makes these bits easy to install and use with common drilling tools.

Suitable for

• Drilling pilot holes in sheet metal and thin plates
• Precision metalworking on small components and brackets
• Maintenance and repair tasks requiring narrow holes
• Use with hand drills and drill presses for small-diameter holes

Key specifications

• Cutting diameter: 2 mm
• Overall length: 49 mm
• Shank type: straight shank for standard chucks
• Quantity: 3 pieces
• Recommended material: metal

How to use

Secure the appropriate bit in the drill chuck and tighten firmly to prevent slippage. Select a drill speed suitable for metalworking—typically moderate to high speeds for small-diameter bits—while using cutting fluid or lubricant to reduce heat and prolong bit life. Position the workpiece on a stable surface or vice, mark the drilling point, and start drilling with light, steady pressure. Retract periodically to clear chips and avoid overheating, and replace bits from the set as needed for consistent results.

Usage recommendations

Use cutting fluid or oil when drilling metal to improve hole quality and extend bit life; avoid excessive pressure to prevent breakage of small-diameter bits. For accurate positioning, consider pilot marking with a center punch before drilling and secure thin sheets with clamps or a vice.
