85mm Bi-Metal M42 High Speed Steel Hole Saw | with Pilot Drill Bit, Smooth Cutting Edge for PVC, Drywall, Wood, Plastic, Gypsum Board, Rubber, Thin

Professional-Grade Cutting Power for Australian Trades Unlock superior drilling performance with the 85mm Bi-Metal M42 High-Speed Steel Hole Saw with Pilot Bit. This hole saw is engineered from top-tier M42 bi-metal, a material renowned for its outstanding hardness, heat resistance, and wear resistance. Even under extreme temperatures and prolonged high-speed use, it retains a razor-sharp edge and resists deformation, ensuring reliable operation job after job. Unmatched Durability and Smooth Cutting The cutting teeth are crafted from M42 high-speed steel with a hardness rating of ≥65 HRC. Combined with a flexible bi-metal body, this design delivers a longer lifespan, smoother cuts, and higher efficiency when tackling hard and thick materials. Whether you are cutting through PVC, drywall, wood, plastic, rubber, or thin metals, expect precise, clean results every time. Effortless Chip Removal and User-Friendly Design We have prioritised user experience with an optimised multi-hole configuration and a spring-guided pilot drill. This system automatically ejects the cutting disc after drilling, dramatically improving chip removal and preventing clogging, especially in deeper or tougher materials. The result is a smoother workflow and reduced downtime. Easy Setup and Broad Compatibility Clear size markings are laser-etched onto the body for quick tool selection. The universal shank fits most electric and cordless drill chucks, ensuring fast installation, a secure grip, and stable torque transmission. This minimises slippage under high loads, making it suitable for plumbing, electrical work, HVAC installation, home DIY projects, and professional trades.
