Hole saw for clean, fast cutting across common materials, the flintronic Bi-Metal Hole Saw promises accurate, burr-free holes. Durable construction and a chip-ejection spring give tradespeople and keen DIYers the confidence to tackle sockets, lights and ducting. Can the design handle both delicate finishes and tougher metals?
⚡ At a Glance
- • Cutting Quality: Fast, accurate cutting with smooth edges and a diameter tolerance under 1mm
- • Best for: Tradespeople, electricians and DIYers cutting holes for lights, ducts and speakers
- • Not ideal for: High-speed production drilling above the recommended RPM limit
M42 high-speed steel paired with bimetal construction gives high hardness and toughness. Carbide-enhanced teeth and an optimised tooth shape speed cutting while keeping edges clean.
Faster, more accurate cuts – with carbide-enhanced tooth shape
Carbide technology increases cutting-edge hardness and an optimised tooth profile reduces resistance; impact-resistant teeth lower the chance of tooth loss during heavy work. The manufacturer allows a cutting-diameter variance of less than one millimetre.
Quicker holes with consistent diameters, reducing time spent on rework and sizing adjustments.
Cleaner holes and quick waste removal – with chip-removal hole and spring ejector
Side chip-removal holes channel swarf away from the cutting face while a spring pushes the cut plug out immediately after the hole is complete. The unconstrained clean-edge design helps prevent cracking and sticking.
Smooth, burr-free openings and automatic plug ejection speed up follow-on tasks such as wiring or fitting fixtures.
Long service life under tough use – thanks to M42 high-speed steel and bimetal construction
The cutting section is made from M42 high-speed steel combined with bimetal construction, delivering higher hardness (≥64HRC) alongside improved toughness. A thin protective oil coating helps resist oxidation and surface corrosion.
Resilient performance across repeated cuts and a range of materials, meaning fewer replacements over time.

❓ Frequently Asked Questions
Q: What materials can the hole saw cut?
A: The hole saw cuts wood, plastic, plywood, drywall, fibreglass, PVC board and a range of metals including mild steel, stainless steel, cast iron, bronze, copper and aluminium.
Q: Will the hole edges be clean enough for fittings like lights and speakers?
A: Yes, the unconstrained clean-edge design combined with an optimised tooth profile aims to produce smooth, burr-free holes suitable for can lights, recessed lights and speaker mounts.
Q: How should cutting speed be managed to extend tool life?
A: Keep rotational speed at or below 1000 RPM for prolonged life and check the coated surface regularly; the thin protective oil layer helps prevent rust but should be handled carefully.
🏆 Our Verdict
Ideal for tradespeople and keen DIYers who need reliable hole cutting across mixed materials. M42 high-speed steel, carbide-enhanced teeth and a chip-ejection spring combine for fast, clean, repeatable holes. While cost may be a consideration, durable construction and reduced rework deliver strong long-term value.
