Sutton bi-metal cobalt holesaws combine a high-speed steel tooth form with an alloy steel backing plate for the combination of cutting performance and shock resistance needed in demanding hole-cutting applications. The 14mm to 152mm diameter range covers the majority of trades and maintenance applications. Where this product is used Used for cutting large-diameter holes in steel, stainless, timber, plastics, and composite materials with electric drills, drill presses, and cordless tools. Cutting lock, cable gland, and conduit entry holes in metal electrical enclosures, switchboards, and control panels in electrical installation work. Plumbing and HVAC pipe and duct penetration holes in steel plate, stainless sheeting, and timber framing. Maintenance and construction hole-cutting in structural steel, handrails, roof sheeting, and composite panel materials. Selecting the right option Select the holesaw diameter to match your required hole size — bi-metal holesaws cut the hole size stamped on the side. Use a pilot drill of 6.35 mm (1/4") or as specified by the arbor. For stainless steel, run at a slow speed with cutting fluid; for timber and plastic, higher speeds without fluid are typically fine.
