## Long description

The Dedra 07F661 cutting countersink bit features a G10×20 mm head and a 6 mm cylindrical shank designed for countersinking and enlarging holes in wood, plastic and soft metals. Manufactured for compatibility with drills and rotary tools that accept a 6 mm shank, this countersink bit is intended for workshop use, drilling jigs and light carpentry tasks where precise chamfering or hole finishing is required.
Advantages
The countersink bit provides a compact head size that enables controlled chamfering and fast material removal on softer substrates. Its 6 mm shank ensures stable mounting in standard chucks and collets, reducing runout and improving concentricity during drilling operations. The geometry of the head is optimised for clean edges and smooth countersinks with minimal tear-out in wood and plastics.
Suitable for
Countersinking screw heads in wooden joinery
Enlarging or deburring drilled holes in plastic parts
Finishing soft metal holes to achieve a chamfer
Use in drilling jigs and small workshop setups
Key specifications
Head diameter: G10×20 mm
Shank type: cylindrical
Shank diameter: 6 mm
Materials suitable: wood, plastic, soft metals
How to use
Secure the countersink bit in a drill or rotary tool with a compatible 6 mm chuck or collet. Align the workpiece and locate the hole to be countersunk. Operate the tool at a moderate speed appropriate for the material: lower speeds for soft metals, medium speeds for plastics and higher speeds for most woods. Apply steady axial pressure and stop periodically to inspect the depth and edge quality. For repetitive operations, use a depth stop or drilling jig to maintain consistent chamfer depth.
Usage recommendations
Wear appropriate eye protection and follow standard workshop safety practices. Keep cutting speeds and feed pressure moderate to reduce heat buildup, and clear chips from the work area to avoid clogging. Test on a scrap piece before working on the final component to confirm the required countersink depth and finish quality.
