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. California Proposition 65 warnings note the product contains chemicals linked to cancer and reproductive harm.

Questions about this item
How much heat and vibration does the 30 mm bi-metal hole saw generate when cutting metal all day?
The M3 high-speed steel teeth are electron beam welded to the blade body for consistent hardness, and the heavy-duty backing plate adds rigidity that reduces vibration during extended cutting in metal, plastic, and wood.
What drill or mandrel must I already own to use the included screw-in mandrel and pilot drill?
The hole saw ships with its own screw-in mandrel and pilot drill, so any standard drill chuck that accepts the mandrel shank will drive it without extra parts.
Will the 30 mm hole saw fit the same arbor as my older 45 mm MIBRO bi-metal saws?
The EZE Slot for quick plug removal is only on blades 45 mm and larger, so the 30 mm saw uses a standard mandrel mount without that slot.
