The Sealey 18mm Diamond Hole Saw is the perfect choice for smaller diameter applications in hard materials. This compact size is ideal for drilling precise holes for cable routing, electrical fittings, and smaller plumbing installations where accuracy is paramount. Featuring an electroplated diamond coating on its cutting edge, this 18mm hole saw delivers chip-free, clean cuts through glass, granite, marble, porcelain, and ceramics with professional results.
The integrated water-cooling sponge system must be soaked in water before use, reducing heat build-up during operation and significantly prolonging the life of the cutting edge. With a 45mm cutting depth, this hole saw provides ample penetration for most plumbing and electrical installation work. The rounded 10mm hex shank ensures secure fitting in both handheld drill and pillar drill chucks, giving you flexibility in your choice of equipment.
