25mm Bi-Metal M42 High Speed Steel Hole Saw | with Pilot Drill Bit, Smooth Cutting Edge for PVC, Drywall, Wood, Plastic, Gypsum Board, Rubber, Thin Metal

Professional-Grade 25mm Hole Saw for Australian Trades

This 25mm Bi-Metal M42 High-Speed Steel Hole Saw with Pilot Bit is built to tackle the toughest materials found in Australian construction and renovation. The M42 bi-metal construction combines a hardened high-speed steel cutting edge (≥65 HRC) with a flexible alloy steel body, delivering outstanding hardness, heat resistance, and impact strength. Even under extreme loads and high temperatures, the teeth stay sharp and the saw resists deformation—giving you consistent cutting performance job after job.

Sharp Cuts, Longer Life

The sharp, sturdy cutting teeth are made from premium M42 high-speed steel, ensuring clean, splinter-free cuts through PVC, gypsum board, wood, plastic, rubber, and thin metals. The bi-metal body provides the flexibility needed to handle vibrations and prevents cracking, extending the saw’s service life significantly. This combination of hardness and flexibility means you get smoother edges, less binding, and higher efficiency when drilling through hard or thick materials.

User-Friendly Features

• Optimized multi-hole design and spring-guided pilot bit automatically eject the cutting disc after each hole—no more manual plug removal.
• Clear, laser-etched size markings let you grab the right size instantly, reducing errors on the job.
• Universal shank fits most electric and cordless drill chucks for quick installation, secure clamping, and stable torque transmission without slippage.

Whether you are a professional plumber, electrician, HVAC technician, or a dedicated DIYer, this hole saw makes drilling faster, cleaner, and more reliable. Add water when cutting metal to maximize its lifespan—a simple trick that pays off in longer tool life and better results.
