With the Carat HT00600000 centring pin, you start core drilling with pinpoint accuracy and eliminate drill bit wandering on hard surfaces. Featuring a 16 mm diameter and an overall length of 60 mm, this pin is purpose-built for the M16 Dustec system. During dry drilling in masonry, sand-lime brick, or brickwork, it delivers stable guidance from the very first rotation. As soon as the core bit establishes its groove in the material, you quickly remove the pin to keep the core clear and complete clean holes for wall sockets and junction boxes with full control.
