RICHELIEU 959471 30 mm bi-metal hole saw with mandrel and pilot

30 mm bi-metal hole saw for mixed materials

This 30 mm bi-metal hole saw handles metal, plastic and wood with its 4/6 variable tooth pitch. The M3 high-speed steel teeth are electron beam welded to a heavy-duty backing plate for rigidity. It ships with a screw-in mandrel and pilot drill so the kit is ready for the job.

Sustained cutting behaviour

The heavy-duty backing plate resists deflection during long cuts, keeping the blade true under load. Electron beam welded M3 teeth maintain hardness and stay sharp through repeated passes in metal, plastic or wood. The variable tooth pitch clears chips steadily, reducing heat build-up during extended use.

Installing and common issues

The screw-in mandrel threads directly into the saw for a secure fit, and the pilot drill centres the cut without extra tools. Blades 45 mm and larger include an EZE Slot for fast plug ejection; this 30 mm size does not, so plugs must be removed manually.
