No time-consuming cleaning anymore

KOCH developed a new method of cleaning the drilling holes.

KOCH developed a new method of cleaning the drilling holes. Tapped blind holes are cleaned during the drilling process. This technique is appropriate for drilling in the stock end of profiled or straight parts and for drillings in grooved long edges.

The special drill block is equipped with two channels, reaching till the top of the drill bit. During the drilling cycle compressed air is put through these channels. The drilling dust is blown out of the tapped blind hole.
