Hole saws for HDT & DAF, for cast pipes

The hole saws are designed for tapping cast pipes and fit the HDT and DAF tapping tools. The saw is fitted in the tool together with a centre drill for cast pipes, which guides and centres the hole saw on engagement so that the hole ends up in the right place. The range covers hole sizes from 19 mm up to 44 mm, covering the hole sizes commonly required for tapping. As all sizes fit the same tool, you only need to add the correct hole saw when a new hole size is required, rather than replacing the whole set of equipment. The centre drill is available as a separate item and is combined with the hole saw size required for the job. For tappings outside this size range, larger tapping equipment can be supplied.
