Starrett KFC14021 16 Piece General Purpose Hole Saw Set

The Starrett KFC14021 is a comprehensive 16-piece hole saw set engineered for professional tradespeople working across multiple materials. Featuring Fast Cut Bi-Metal construction with extra cobalt HSS tooth material, this general-purpose kit delivers enhanced heat and wear resistance for extended service life. The innovative 5.5 TPI positive rake tooth design reduces torque whilst ensuring smoother, faster cutting performance compared to traditional constant pitch designs.

Specifically engineered to cut stainless steel, mild steel sheet and metal tubes up to 3mm thickness, this versatile set also handles wood, plastic, plaster and other materials effectively. The 30% increased gullet volume improves material penetration and chip clearance during operation, whilst the cobalt-enriched tooth material maintains cutting edge integrity under demanding conditions.

This professional kit provides fourteen hole saw sizes from 16mm to 76mm, covering the most frequently required diameters for electrical, plumbing, HVAC and general construction applications. Supplied complete with two arbors (A1 and A2) and an ejector spring (A7), the set provides everything needed for immediate deployment on site.
