Blowing device for drilling holes

Clean drilling holes for maximum product quality

The innovative KOCH blowing device for drilling holes ensures chip free drilling holes, which improves the quality and stability of your dowel connection immensely. We specifically recommend this technology for the processing of sensitive workpiece surfaces, since here no unnecessary flying chips can mark or even damage them. Furthermore, the integrated chip removal intensifies the effect of the blowing device even more.
The blowing device for drilling holes is available for 8 as well as for 6 mm drillings and can be used for workpieces made out of MDF, chipboard and solid wood.
