Starrett KFC11021 13 Piece Deluxe Electricians Hole Saw Set

The Starrett KFC11021 is a comprehensive 13-piece hole saw kit specifically designed for electricians working with a variety of materials including stainless steel, mild steel sheet, wood, plastic and plaster. This fast cut bi-metal hole saw set features extra cobalt HSS tooth material and a 5.5 TPI positive rake tooth design, delivering enhanced heat and wear resistance alongside smoother, faster cutting performance compared to traditional constant pitch hole saws.

The advanced tooth geometry provides 30% extra gullet volume for superior material penetration and chip clearance, whilst the positive rake design reduces torque requirements for easier operation across all materials. The cobalt-enhanced tooth material extends product life, making this set ideal for electricians regularly cutting through 3mm stainless steel, mild steel sheet and tubes, or materials up to 13mm thickness.

The kit covers the most commonly required sizes for electrical installation work, ranging from 16mm through to 76mm diameter, along with two arbors (A1 and A2) and an ejector spring (A7) for efficient operation. The 41mm cutting depth capability ensures versatility across various installation scenarios, from conduit and cable entry points to consumer unit knockouts.
