Our concave cutters with outstanding TWINCUT blade geometry for quick and precise working. The TOP tool for your chatons. Chatons comprise several sharp-edged claws which have to be rounded-off, smoothened and shortened if necessary. With the TWINCUT concave cutters, the three steps can be undertaken quickly and safely in a single operation. The conical version 411CT is for a better overview. 411T is now available in two new sizes: extra filigree in 007, and in 025 for larger chatons.
