Drill bits for hard surfaces, engineered to cut clean holes through porcelain, ceramic and natural stone, the SHDIATOOL Diamond Drill Core Bit promises fast, wear-resistant drilling. Tradespeople and keen DIYers gain confidence when making neat holes for fixtures without cracking tiles. Are these dry bits the right choice for heavy-duty tile work and frequent use?
⚡ At a Glance
- • Cutting Quality: Fast, clean cuts in hard materials thanks to vacuum-brazed diamond segments and temperature-resistant industrial diamonds
- • Best for: Tradespeople and DIYers drilling porcelain stoneware, ceramics, marble and granite with M14 angle grinders
- • Not ideal for: Use with standard drills lacking M14 thread unless an adapter such as SDS Plus, Hex or round shank is fitted
Two vacuum-brazed diamond core bits, 6mm diameter and 60mm total length, feature an M14 thread for angle grinders. Vacuum brazing and a self-cooling wax core produce durable, fast drilling in hard tiles and stone.
Fast, precise holes - with vacuum-brazed diamond segments
Vacuum brazing permanently bonds industrial diamond grains to the steel core, making segments heat resistant and extremely durable. A 10mm diamond height gives a robust cutting edge for longer service life.
Faster cutting reduces time spent on each hole and keeps edges tidy, useful when drilling multiple tiles or stone slabs.
Reliable dry drilling for hard tiles - with temperature-resistant diamonds
High-quality, temperature-resistant diamonds tolerate heat generated during dry drilling, while a cooling wax core helps with self-sharpening. Recommended operating speed is 6000 RPM, with safe use up to 11000 RPM.
Suitable for making anchor and fixture holes in porcelain and granite without needing a continuous water supply, ideal for on-site work where wet setups are impractical.
Quick tool mounting - with universal M14 thread
A standard M14 connection fits most angle grinders directly; adapters are available for SDS Plus, hex or round shanks if other tools are required. Total length is 60mm for manageable reach.
Ready to use on common angle grinders, allowing immediate work on tiling jobs; adapters extend compatibility to other drills when necessary.
