Starrett 51 mm Diameter HSS Bi-Metal Hole Saw Kit KFC06021

Starrett KFC06021 Bi-Metal Hole Saw Kit features eight pieces including a 51 mm diameter holesaw with a cut depth of 3 mm, designed using high-speed steel (HSS) bi-metal material for durability and heat resistance. This kit includes holesaws with diameters of 16 mm, 20 mm, 25 mm, 32 mm, 40 mm, and 51 mm, covering a broad range of drilling needs. It comes supplied with Arbor types A1 and A10, suitable for diameters from 14 mm up to 210 mm, enabling versatile application.

The holesaws feature an extra cobalt HSS tooth material enhancing heat dissipation and wear resistance, significantly extending tool lifespan. The 5.5 TPI (teeth per inch) positive rake tooth design minimizes torque requirement, enabling faster and smoother cuts through stainless steel, mild steel sheets up to 3 mm in thickness, as well as wood, plastics, and plaster.

With 30 percent extra gullet volume, material penetration is improved, and a holesaw depth of 41 mm allows for deep precise cuts. The Fast Cut bi-metal design of this holesaw kit reduces torque load for the tool and supports efficient cutting performance in industrial, manufacturing, and construction environments.

The kit contains 8 precision holesaws of varying diameters, extending from 16 mm to 51 mm. Arbors included allow for adaptability across a wide diameter range, fitting multiple machines. Durable extra cobalt HSS construction ensures long service life and reliability under heavy use.

5.5 TPI tooth design offers improved cutting speed and surface finish quality. Designed for cutting stainless steel, metals, mild steel sheets, as well as wood and plastics. 30% increased gullet volume facilitates better chip removal and cooler cutting.

Holesaw depth at 41 mm supports applications requiring deeper penetration. Ideal for commercial, industrial, and mechanical tool applications in manufacturing.
