Precision-Cut with M42 Bi-Metal Durability This 19mm hole saw combines a tough M42 high-speed steel tooth edge with a flexible bi-metal back, delivering a perfect balance of sharpness and resilience. The teeth maintain their cutting edge even under high temperatures and sustained high-speed use, resisting deformation for consistent performance on job after job. Efficient Chip Removal & Easy Ejection Our innovative multi-hole design and spring-loaded pilot drill automatically push out cut discs once the hole is complete. This feature significantly improves chip evacuation and reduces clogging, especially when cutting thicker or harder materials like metal or hardwood. You stay productive without unnecessary pauses. Quick, Secure Setup for Any Task Dimensions are clearly laser-etched on the saw for instant identification. The 1/2-inch universal shank fits most electric and cordless drills, locking in place for stable torque transmission and minimal slippage under heavy load. Change between sizes swiftly and safely. Versatile Across Materials & Applications From softwoods and plywood to PVC, plasterboard, plastics, rubber, and thin metal sheets, this hole saw handles them all. Whether you're a tradesperson in plumbing, electrical, or HVAC, or a home DIY enthusiast, this tool earns its place in your kit.
