Countersink drill bit Bosch 2608596667 8.0 mm 10.0 mm 12.0 mm

The Bosch countersink drill bit set 2608596667 includes three single-cut countersinks with diameters of 8.0 mm, 10.0 mm and 12.0 mm. Designed for precise countersinking, the set is suitable for use in wood, plastic and non-ferrous metals and is supplied in a blister pack. The bits have a 90° cutting edge and left-hand rotation for controlled chip removal and clean countersink edges.

Advantages

The three-piece set covers common countersink sizes for fast selection on the job. A single 90° cutting edge provides accurate chamfering and consistent hole geometry. Left-hand rotation improves chip evacuation and reduces the risk of material tear-out when working with softer substrates. Compact blister packaging keeps the bits organized and visible for quick identification.

How to use

Select the countersink diameter that matches the screw head or chamfer size required. Secure the workpiece and position the drill bit at the hole center. Use a drill or driver at moderate speed, applying steady axial pressure until the desired countersink depth is reached. Retract periodically to clear chips; the left-hand rotation aids evacuation. Verify fit of the screw head or chamfer and adjust depth if necessary.

Recommendations

Use appropriate clamps and eye protection. For best results in metal, apply light cutting lubricant and use controlled speed. Avoid excessive feed pressure to prevent bite-in or oversized countersinks.
