Customised reaming tools

Always taking the utmost care to ensure that our solutions are totally customised and respect the conditions of use and needs of our customers, we design and build special counterbores and reamers in HSS-Co and solid carbide or carbide-brazed metal, available with one or more diameters and between three and six edges for a better finish. We make hand and machine countersinks and reamers with special attachments, or standard cylindrical ones, and Iso, Weldon and Varilock holder, in line with contemporary-industry requirements.

Our special reamers and counterbores with non-standard lengths and measurements are created and subsequently verified thanks to our sophisticated internal checks. These checks are annually certified by a specially appointed external company with the aim of ensuring that quality is guaranteed for our customers. Now, at the end of the production cycle, each tool comes with a personal control sheet for the user, which details the tool’s general tolerance parameters.
