The Sealey 20mm Diamond Hole Saw offers versatile performance for a wide range of drilling applications in hard materials. This popular mid-range size is particularly well-suited for electrical installations, plumbing fittings, and general purpose hole cutting in tiles and stone surfaces. Featuring an electroplated diamond coating, the 20mm cutting edge delivers precise, chip-free holes through glass, granite, marble, porcelain, and ceramics with exceptional accuracy. The integrated water-cooling sponge system must be soaked in water before use, effectively reducing heat build-up during operation and prolonging the cutting edge life for consistent performance over time. With a generous 45mm cutting depth, this hole saw provides excellent penetration for plumbing and electrical installation work. The rounded 10mm hex shank design ensures secure, wobble-free fitting in both handheld drill and pillar drill chucks for maximum versatility.
