Hole Saws - Carbide Tipped CTD (Deep Cut)

Starrett CTD carbide-tipped deep-cut hole saws combine two things: tungsten carbide teeth for durability and an extra-deep body for depth of cut. They are ideal for thick or abrasive materials where you need both. Typical uses include masonry board, render, thick timber and reclaimed materials with embedded fixings, especially when the material is too thick for a standard-depth hole saw. Diameters run from 15mm to 100mm in small steps, so it is easy to find a close match for the pipe, cable or fitting you need to pass through. How to choose: choose CTD over the standard CT range when the material is thicker than the cutting depth of a standard hole saw. For non-abrasive timber and stud walls, the DCH bi-metal deep-cut range is an alternative. Usage tips: on deep cuts, back the hole saw out periodically to clear debris, keep the speed moderate and steady, and make sure the pilot drill is sharp so the hole saw starts in the right place. What makes CTD different from CT? Both use tungsten carbide teeth; CTD adds an extra-deep cutting body for thicker materials. Is CTD suitable for reclaimed timber? Yes, it is a reliable choice for reclaimed materials with embedded fixings, as well as thick timber.
