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.
