Professional 10-Piece Vacuum Brazed Diamond Core Drill Bit SetThis M14 set combines five precision diameters with five popular core sizes, giving tile and stone installers a practical solution for plumbing, fittings, anchors and general hole preparation. The vacuum brazed diamond coating provides fast cutting, stable performance and efficient heat dissipation on porcelain, Gres, granite, Dekton, quartz and marble.
Standard configuration: Ø6, 8, 10, 12, 14, 20, 25, 30, 35 and 50 mm. Other diameters, M10 or 5/8”-11 connections and customized combinations can be supplied on request.
Designed mainly for angle grinders and dry drilling. Begin at a slight angle, then gradually bring the tool upright as the cutting groove forms. Light water cooling can reduce heat and extend service life. Do not use hammer mode.
The reinforced aluminum carrying case protects the bits, keeps all sizes organized and provides a professional presentation for distributors, trade users and private-label programs. OEM colors, logos and packaging are available.
