Countersinks – deburr holes and make screw heads disappear

Since the edges of a drill hole in metal are very sharp, they should always be deburred with a countersink. In this way, you prevent cuts and contain a flat surface.

If you want to countersink the screw in the workpiece, then machine the hole with a countersink. Then drill a tapered hole to countersink head screws into the material. In this way, the head of the screw is flush with the surface of the workpiece.  

Countersink and cross hole countersink

With the BAER countersink you create tapered shoulders or precisely deburr the drill hole. The countersink has two to three cutting edges. It is available in different hardnesses for different materials. This ensures that you achieve the best result with the right choice of tool. The cross hole countersink with its peeling cut ensures that the chips are carried out of the countersink through the cross hole.

On one view

Existing holes are reworked with the countersink:

  • Deburring - for smooth cut edges
  • Sinking - for countersinking screws

HSSG countersinks for normal applications

Do you want to machine normal steels, cast iron, iron, sheet metal, aluminum and light metals up to 800 N/mm² with the countersink? Then the BAER-HSSG countersink made of high-performance high-speed steel is the right choice. With it you can countersink, deburr and countersink without burrs and chatter.

HSSG countersinks with 1/4“ bit for cordless screwdrivers

Either do-it-yourselfer or the professional craftsman - cordless screwdrivers can be found in almost every toolbox. For this and for turning handles or ratchets with 1/4" bit drive, these countersinks made of high-performance high-speed steel with special shank are the right solution. They are suitable for machining normal steels, cast iron, iron, sheet metal, aluminum and light metals up to 800 N/mm².

Countersink sets

Several sizes at the same time in one handle: This is what we offer you with the BAER countersink sets. The plastic box stacks well, closes securely and opens easily. The countersinks are clearly presented in different sizes - all you have to do is choose.

HSSE-VAP countersinks for stainless steels

For countersinking in stainless steel a special tool material is necessary. The HSSE-VAP countersinks from BAER with the vaporized surface and the HSSE types with cobalt alloy meet this requirement. Best results are achieved at low cutting speeds. Suitable for stainless steels V2A, V4A, Inox and high-strength steels.

HSSG cross hole countersink without chip jamming

In contrast to the taper countersink, the cross hole countersink has a lateral opening through which the chips are discharged. This prevents jamming of the chips between the drill and the workpiece. With BAER HSSG cross hole countersinks, which are mainly used for deburring, you achieve clean results with easy handling.
