76 mm Bi-Metal Hole Saw

This RICHELIEU 962531 hole saw cuts 76 mm diameter holes in metal, plastic, and wood. It ships with a screw-in mandrel and pilot drill already included. M3 high-speed steel teeth are electron-beam welded to a heavy-duty backing plate for rigidity and consistent hardness. The 4/6 variable tooth pitch is designed for efficient and safe cutting across those materials.

Trade users needing a ready-to-use 76 mm cutter

The kit suits electricians, plumbers, and general contractors who want a single 76 mm saw with mandrel and pilot drill in one package. The EZE Slot on this diameter allows quicker plug removal after the cut. Buyers who need multiple diameters or a full hole-saw set should look at something else. The product also carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.

Simple mandrel fitment with one common snag

The screw-in mandrel threads onto the saw and chucks into a standard drill, so setup takes seconds. The pilot drill centres the cut automatically. The most frequent issue is the plug sticking inside the saw despite the EZE Slot; a screwdriver usually frees it. Ensure the workpiece is clamped securely because the 76 mm diameter generates strong torque reaction.

Questions about this item

Do I need a specific drill chuck size to run the 76 mm hole saw?

The included screw-in mandrel fits standard drill chucks, so the saw mounts directly without an extra adapter.

Will the 4/6 variable tooth pitch cut through older steel pipe as cleanly as new stock?

Yes, the M3 high-speed steel teeth are electron beam welded for consistent hardness, giving efficient cuts in metal, plastic and wood regardless of pipe age.

How can I confirm the EZE Slot is ejecting plugs correctly after the first hole?

After drilling, check that the slug releases from the slot without prying; smooth ejection means the 45 mm and larger blade feature is working as intended.
