The Starrett KDC10022 is a comprehensive 13-piece deep cut hole saw set designed specifically for plumbers and contractors working with pipes, tubes and solid materials. This deluxe kit combines Starrett's aggressive tooth form with extra cobalt HSS teeth to deliver exceptional heat and wear resistance across demanding applications. Featuring an extended 51mm cutting depth, these deep cut bi-metal hole saws excel at penetrating through both sides of pipes and tubes in a single pass, making them ideal for plumbing installations. The increased depth provides superior cutting performance on thick-walled tubes over 3mm and solid materials including metals, wood, plastic and plaster. The 4-6 TPI aggressive tooth configuration ensures rapid material penetration and efficient kerf clearance. The enhanced cobalt HSS tooth material significantly extends product life whilst maintaining sharp cutting edges under demanding conditions. The design reduces vibration during operation, delivering smooth cutting action that minimises user fatigue during extended use. This set includes two arbors (A1E and A2E) with extended length pilot drills required for the 51mm depth, plus an ejector spring for easy slug removal.
