Flintronic 120mm Bi-Metal Hole Saw
Product description
Flintronic's 120mm bi-metal hole saw blends faster cutting and durable construction for routine trade and DIY tasks. It is designed for cutting clean holes in wood, plastics and a range of metals, making it practical for installing recessed lights, vents or speaker housings.
Key points
Made from M42 high-speed steel and bimetal, this cutter claims enhanced hardness and toughness, with an arc-shaped tooth design for improved concentricity and wear resistance. The blade uses a carbide-style hardening process that, according to the manufacturer, improves cutting speed and reduces tooth loss. Expect smoother edges and consistent diameter within about one millimetre when used at appropriate speeds.

Benefits
This hole saw is robust enough for repeated use and offers better chip ejection thanks to a dedicated removal hole and spring that pushes out the cut disc. That reduces clogging and the risk of heat build-up. The protective oil coating helps prevent corrosion in storage, though light cleaning before use is advised.
Best use cases
It makes sense if you need a reliable 120mm cutter for fitting ceiling downlights, air outlets or routing larger cables through panels. Take care with prolonged work on harder metals, keep the RPM under the recommended limit and check the condition of the teeth periodically. You’ll like it if you prioritise cleaner edges and straightforward chip removal over lowest-cost disposable options. 😊🛠️ Flintronic 120mm Bi-Metal Hole Saw offers a practical balance of speed and durability, and is compatible with bench drills, drill presses and most hand drills. 🔧🪚
