Drill bits set Dedra WMT08011 — 8 mm diameter, 117 mm length, 10 pcs, for metal

Dedra WMT08011 is a set of ten 8 mm drill bits, each 117 mm long, designed specifically for drilling metal. The bits are supplied as identical pieces to ensure consistent hole diameter when used in hand-held drills or drill presses. This kit is intended for through-holes and pilot drilling in steel and similar ferrous and non-ferrous metals commonly encountered in fabrication, repair and maintenance tasks.

Advantages

The 8 mm diameter and 117 mm length provide a balance between reach and rigidity for metal drilling operations. Supplied in a pack of ten, the set reduces downtime by providing immediate replacements when bits dull. The consistent geometry across the set supports repeatable hole sizes and predictable cutting behaviour in metalworking. Compatibility with standard drill chucks makes the bits suitable for both portable and stationary drilling equipment.

Suitable for

• Through-holes in steel sheets and plates
• Pilot holes for fastening and tapping operations
• Repair and maintenance on metal structures and components
• General metal fabrication and workshop tasks

Key specifications

• Drill bit diameter: 8 mm
• Overall length: 117 mm
• Material suitability: metal (steel and similar materials)
• Quantity in set: 10 pieces
• Compatible with standard drill chucks and drill presses

How to use

Select an appropriate rotational speed and feed for the specific metal being drilled, secure the workpiece, and use cutting fluid where recommended to reduce heat and improve chip evacuation. Fit the 8 mm bit securely in the drill chuck, align the point with the marked hole position and start drilling with steady pressure. For through-holes, back the drill out periodically to clear chips; for pilot holes, follow with the required larger drill or tapping operation as needed.

Usage recommendations

Use cutting fluid and appropriate drill speeds for the metal type, clamp the workpiece to prevent movement, and replace worn bits from the pack to maintain hole quality. Inspect bits before use for straightness and sharpness to ensure safe and accurate drilling.
