About this product

Professional-Grade Cutting Performance

This 185mm Bi-Metal M42 HSS Hole Saw with Pilot Bit is engineered for both DIY enthusiasts and professional tradespeople across Australia. Constructed from premium M42 bi-metal high-speed steel, it delivers exceptional hardness, heat resistance, and wear resistance, maintaining a sharp cutting edge even under high temperatures for long-term, high-speed operation without deformation. Its superior material quality ensures a longer lifespan compared to ordinary hole saws.

Outstanding Efficiency and Precision

The sharp and robust cutting teeth, made from M42 high-speed steel (≥65 HRC), combined with a flexible bi-metal body, provide a smoother cut and higher efficiency when tackling hard and thick materials. Whether you are working on sheet metal, 45# steel, artificial board, wood, gypsum board, or plastic, this hole saw delivers consistent, precise results every time.

User-Friendly Design

User experience is a top priority. The optimized multi-hole design and spring-guided drill automatically eject the cutting disc after drilling, improving chip removal efficiency and reducing blockages, especially when cutting thick or hard materials. This feature saves you time and effort during your projects.

Easy Installation and Secure Fit

Clear size markings allow for quick and easy selection of the right size. The shank design is compatible with most electric and cordless drill chucks, ensuring fast installation, a secure clamp, and stable torque transmission. This reduces slippage under high loads, enhancing safety and performance.
