The HSS conical countersink for countersinking existing bore holes in metal and plastic is made of high-speed steel (HSS) and is valued for its high heat resistance and long service life. The countersinking angle is 90°, which enables you to prepare clean holes for flush screw connections with countersink screws.
Here the adjustable depth stop helps you to create evenly sunk holes with a diameter of up to 16.4 mm. Its special shape provides an unobstructed view of the work area. To protect the surface, the depth stop has a closed edge that distributes the pressure evenly.
The special 3-edge cutting geometry of the conical countersink ensures very quiet running and fast work progress. The cutting edges are with radial relief, so that you can create clean countersunk holes without tear-out and profit from the fast work progress. The triangular shank ensures a secure fit in the drill chuck. The conical countersink is produced in Germany – that means you are investing in a high-quality, durable product.
