About this item
- 【Ultra-Hard M42 Bi-Metal Build】Bi-metal hole saw set crafted from premium M42 high-speed steel bi-metal alloy, the cutting teeth boast 65-66HRC hardness—far tougher than standard carbon steel. Arc design ensures precise, high-concentricity cuts; rust-proof, wear-resistant coating boosts durability. Heat-treated for enhanced toughness, it cuts wood/metal/PVC smoothly with extended service life.
- 【Blazing Speed & Pinpoint Accuracy】Boosted by premium carbide technology for enhanced hardness and optimized tooth geometry, our hole saw drill bit delivers faster cutting and pinpoint accuracy that outperforms standard models. Its high-speed steel blade features impact-resistant teeth that prevent tooth loss, ensuring cutting diameter deviation stays under 1mm for consistent, reliable results every time.
- 【Easy Operation & Hassle-Free Chip Removal】Our wood hole cutters features a clean-edge design for smooth, unobstructed cutting. Upgraded chip removal holes clear debris fast to avoid jamming and cracking. The spring-loaded hole drilling cutter automatically ejects the wood chip disc post-drilling, saving time, reducing shock and protecting the saw.
- 【13-Piece Metal Hole Saw Kit】You’ll receive 13 hole saws in diameters 18, 20, 22, 25, 28, 30, 35, 38, 45, 50, 55, 65 and 75mm, covering most aperture needs. The effective cutting depth is 30-35mm. For prolonged use, keep RPM ≤ 1000 to avoid excessive high-speed wear on the saws.
- 【Wide Application】13PCS metal hole saw cutter ideal for cutting wood, plastic, mild steel, stainless steel, cast iron, bronze, copper and aluminum. Our hole opener kit perfect for drilling holes for can lights, recessed lights, air ducts, ceiling lights and speakers. Compatible with bench drills, drill presses, gun drills and all types of hand drills.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
