About this item

Professional-Grade 75mm Bi-Metal Hole Saw for Australian Trades Designed for demanding drilling applications, this 75mm bi-metal hole saw combines M42 high-speed steel teeth with a flexible body to deliver outstanding durability and performance. The M42 material (≥65 HRC) ensures superior heat and wear resistance, maintaining a sharp edge even during extended high-speed use. Key Features M42 Bi-Metal Construction: High-speed steel teeth welded to a spring-steel body reduce breakage and extend tool life. Optimised Cutting Geometry: Multi-tooth design and deep gullets for efficient chip removal and smooth, fast cuts. Automatic Disc Ejection: Spring-loaded pilot drill pushes out cutting discs after each hole, minimising handling time. Universal Compatibility: Fits standard drill chucks with a robust 11mm shank for stable torque transmission. Clear Markings: Laser-etched size marks on the body match the cutting diameter for quick selection. Versatile Application Perform clean cuts in PVC, gypsum board, wood, plywood, plastic, rubber, and thin metal sheets (up to 3mm). Ideal for electrical conduit installation, plumbing, HVAC, and general DIY tasks. For best results on metal, apply coolant to reduce friction and heat buildup.
