Description

The Tungsten-Tipped Holesaw 20mm (2040 1020) is a premium hole saw engineered for cutting through particularly hard or abrasive materials — including hard ceramics, tile backerboard, fibre cement, and reinforced panels — where standard bi-metal teeth would quickly dull and fail. The tungsten carbide tips are brazed to the saw body and maintain their cutting edge far longer than HSS alternatives in these demanding materials.
The 20mm diameter suits standard small conduit entries, cable gland holes, and specific fitting sizes in tiled and hard-wall surfaces. The tungsten-tipped construction makes this saw ideal for use in kitchens and bathrooms where electrical work often requires cutting through tiled or hard-lined surfaces.
The premium material and construction of the tungsten-tipped saw means it represents a higher initial investment than bi-metal alternatives, but its significantly extended service life in hard materials provides a strong overall cost-of-ownership benefit for contractors who regularly work in these environments.
