Grinding pin for grinding drill holes

The high-quality countersink with internal cooling is the ideal solution for deburring your drill holes!

Durable grinding pin for precise deburring

A countersink is required to remove the sharp edges that occur when drilling a hole in materials such as glass or gemstones. The grinding pin is water-cooled and perfectly suited for simple and safe deburring of your drill holes. In addition, this highly useful diamond tool impresses with its robustness and long service life.

Fully sintered diamond tool for professionals

The countersink with internal cooling from Günther Diamantwerkzeuge is fully sintered. During the sintering process, fine-grained ceramic or metallic materials are heated – often in combination with increased pressure. As the melting temperature of the main components is not reached, the shape of the grinding pin is retained. The grinding pin from Günther Diamantwerkzeuge is ideally suited for professional use.

Your countersink with internal cooling

The grinding pin is extremely durable and robust, as it is completely impregnated with diamond. With the countersink, you can smooth the edge of the drilled hole quickly and easily. To ensure a perfect result with this high-quality diamond tool, a fine diamond grit has been selected. After this “chamfering” process, you can pass cords through the drilled hole without the risk of tearing at the edges. Even leather cords will not wear down in the deburred holes and will retain their shape.
