Hole saws for concrete

Hole saws for concrete are used for drilling and tapping in concrete structures, for example in manholes, chambers and concrete pipes where a new connection is to be made. The saws are available in a wide range of diameters from 138 mm up to 341 mm, allowing the hole to be matched to the connection or pipe to be installed. The cutting depth is 200 mm, which is sufficient for drilling through normal wall thicknesses found in concrete. The sizes follow a consecutive series where the designation states the saw's diameter, making it easy to choose the right tool based on the required hole size. The hole saws are fitted to a suitable drill or drilling equipment for drilling in concrete. If heavier equipment is needed for larger holes, this can be supplied separately.
