Drill bit Dedra WK11014 — diameter 11 mm, length 142 mm, for metal, 1 pc

Single Dedra WK11014 drill bit with 11 mm diameter and 142 mm overall length designed for drilling metal. The straight-shank, high-speed steel geometry is suitable for producing clean round holes in steel and other ferrous materials when used in handheld drills and drill presses. This 1 pc metalworking bit is intended for maintenance, repair and fabrication tasks that require precise through-holes or pilot holes in sheet metal, plates and structural components.

Advantages

This drill bit combines an 11 mm cutting diameter with a long 142 mm body to reach deeper drilling positions while maintaining rigidity in typical workshop and on-site conditions. The straight shank fits common drill chucks for rapid installation and stable rotation. Its geometry and material selection provide reliable chip evacuation and consistent hole quality in metals when used at recommended speeds and with proper coolant or lubrication.

Suitable for

• Drilling through mild and medium carbon steel
• Creating pilot holes for bolts and rivets in metal assemblies
• Maintenance and repair tasks on machinery and metal structures
• Metal fabrication and sheet metal work requiring precise round holes

Key specifications

• Cutting diameter: 11 mm
• Overall length: 142 mm
• Shank type: straight shank for standard chucks
• Intended material: metal (steel and other ferrous materials)
• Quantity: 1 piece

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the shank is fully inserted and tightened. Select an appropriate spindle speed for the material and diameter — lower speeds for harder steels and larger diameters — and apply cutting fluid or lubrication when drilling steel to reduce heat and improve chip evacuation. Start with a center punch or pilot mark to prevent walking, then drill with steady pressure and allow the bit to clear chips periodically. After drilling, remove burrs as required.

Usage recommendations

Use recommended cutting speeds and lubrication for metal drilling, clamp workpieces securely, and avoid excessive feed pressure to prolong bit life and maintain hole accuracy. Replace the bit if wear or chipping affects hole quality.
