MATRIXTEC core bit set with countersink cutter, art. no. 55840

 

 

Precise drilling and clean chamfering with the practical core drill set

This high-quality core drill set combines two essential tools for professional tilers, stone workers and craftsmen: the MATRIXTEC diamond dry core drill set (Ø 20, 38, 50, 65 mm, art.-no. 50840) and the diamond countersink bit Ø 50 mm with M14 thread (art.-no. 50255). With this complete package, you cover all work steps reliably – from precise drilling to enlarging existing holes and clean chamfering.

Advantages of the drill bit set

The drill bit set impresses with its versatility and high-quality workmanship. With the four core bits in diameters of 20, 38, 50 and 65 mm, you are ideally equipped to drill clean holes in porcelain stoneware, tiles and natural stone. Supplemented by the diamond taper countersink cutter, drill holes can be enlarged exactly and edges chamfered precisely. Both tools have an M14 holder and therefore fit on standard angle grinders. Thanks to the innovative matrix coating of the core bits, you benefit from a long service life and consistently high drilling performance, while the diamond coating of the taper milling cutter ensures reliable material processing. The included transport case makes the core bit set a practical and durable complete solution for professional use on the construction site.
