80mm 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 80mm Hole Saw for Australian Trades Upgrade your toolkit with our 80mm Bi-Metal M42 High-Speed Steel Hole Saw, precision-engineered for Australian tradespeople and DIY enthusiasts. This hole saw combines M42 steel’s legendary hardness with a flexible bi-metal back, delivering outstanding resistance to heat and wear. Even during prolonged high-speed drilling, the cutting edge stays razor-sharp and deformation-free, ensuring consistent results on every project. The cutting teeth are precision-ground to a hardness of ≥65 HRC, providing exceptional durability and smooth, clean cuts in hard and thick materials. The bi-metal construction flexes under stress to reduce breakage, giving you longer service life and reliable performance job after job. We’ve designed this hole saw for maximum efficiency. Its multi-hole pattern and spring-guided pilot drill automatically eject slugs after cutting, dramatically improving chip removal and reducing clogging in deep or tough materials. This means faster work with less downtime. Easy setup and a secure fit are built in. Clear, laser-etched size markings let you grab the right saw instantly, while the standard shank fits most electric and cordless drill chucks. The snug grip and stable torque transfer minimise slippage even under high loads, giving you confidence in every cut. Versatility is key. Whether you’re drilling through wood, plywood, plastic, PVC, gypsum board, rubber, or thin metal sheets, this hole saw handles it all. Perfect for plumbing, electrical, HVAC installations, home renovations, and professional workshops, it’s a reliable companion for any job.
