Drill bits Dedra WMT12015, diameter 1.2 cm, length 151 mm, set of 5, for metal

Dedra WMT12015 is a set of five drill bits with a 1.2 cm diameter and 151 mm overall length designed specifically for drilling metal. These drill bits are intended for use in standard drill chucks and are suitable for producing through-holes, fabrication and repair tasks on a variety of metal parts. The set provides uniform geometry across all five pieces for consistent hole quality when used with proper drilling speeds and cutting fluids.

Advantages

The set includes five identical drill bits, allowing repeatable performance and convenient replacement during extended work. With a 1.2 cm diameter and 151 mm length, the bits reach deeper into assemblies while maintaining stability in the chuck. Designed for metalworking, the bits offer reliable cutting when combined with appropriate feed rates, speeds and lubrication. Compatibility with common drill chucks makes the set suitable for both handheld and bench-mounted drills.

Suitable for

• Drilling through metal sheets and plates
• Fabrication and assembly of metal parts
• Repair and maintenance of machinery and equipment
• Pilot and clearance holes for bolts and fasteners

Key specifications

• Diameter: 1.2 cm
• Overall length: 151 mm
• Material suitability: metal
• Quantity in set: 5 pieces
• Compatibility: standard drill chucks, handheld and bench drills

How to use

Secure the selected drill bit firmly in the drill chuck and ensure correct alignment. Mark the drilling location and clamp the workpiece to prevent movement. Select an appropriate drill speed for the metal type and apply cutting fluid or lubricant to reduce heat and improve chip evacuation. Start drilling with steady pressure, withdrawing occasionally to clear chips if drilling deep holes. After use, clean the bits of debris and store them dry to prevent corrosion.

Usage recommendations

For optimal results, match drill speed and feed to the specific metal being drilled (slower speeds for harder alloys), use cutting fluid to extend tool life, and wear appropriate eye and hand protection. Replace bits when wear or damage affects hole quality.
