Sealey Diamond Hole Saw 30mm

The Sealey 30mm Diamond Hole Saw offers robust performance for larger diameter applications in demanding materials. This size is ideal for substantial plumbing installations, electrical junction boxes, and larger tile penetrations where precision and clean edges are crucial for a professional finish. The electroplated diamond coating on the 30mm cutting edge ensures precise, chip-free holes through glass, granite, marble, porcelain, and ceramics with reliable, consistent results. The integrated water-cooling sponge system must be soaked in water before use, reducing heat build-up during operation and significantly extending the life of the cutting edge for long-term value. With a 45mm cutting depth, this hole saw delivers ample penetration for most plumbing and electrical installation projects. The rounded 10mm hex shank provides secure, stable fitting in both handheld drill and pillar drill chucks, giving you complete flexibility in your choice of equipment and working position. Featu
