About this item

Professional-Grade 16mm Bi-Metal Hole Saw Upgrade your drilling toolkit with this 16mm M42 bi-metal hole saw, engineered for Australian tradespeople and DIY enthusiasts. The cutting teeth are made from premium M42 high-speed steel (≥65 HRC), delivering outstanding hardness and heat resistance. This means the saw stays sharp even under heavy use, cutting through tough materials with precision and speed. The unique bi-metal construction combines a flexible steel body with hardened teeth. This design resists cracking and breakage, giving you a long-lasting tool that handles demanding jobs. Whether you're drilling PVC, gypsum board, wood, plastic, rubber, or thin metal, expect clean, burr-free holes every time. Designed for Efficiency and Ease We've optimised the user experience with practical features. The multi-hole body and spring-loaded pilot drill automatically eject waste material after cutting, preventing clogging and reducing downtime. Dimensions are clearly marked for quick size selection, and the robust shank fits most electric and cordless drill chucks. Installation is fast, clamping is secure, and torque transmission is stable—even under high loads. This hole saw is ideal for plumbing, electrical work, HVAC installation, and home projects. If you're a professional tradie or a weekend warrior, this tool delivers reliable performance. Recommendations for Best Results For drilling in metal, apply lubricant (e.g., cutting oil or WD‑40) to reduce friction and extend the saw's life. Start at a slow speed to establish a clean edge, then gradually increase. Use sharp pilot drill bits for accurate alignment and reduced vibration.
