RICHELIEU 960591 Bi-Metal Hole Saw

This RICHELIEU 960591 bi-metal hole saw cuts 1 5/16-inch (33 mm) diameter holes in metal, plastic, and wood. A heavy-duty backing plate provides rigidity while M3 high-speed steel teeth are electron beam welded for strength and consistent hardness. The 4/6 variable tooth pitch supports efficient and safe cutting across these materials. The package includes a screw-in mandrel and pilot drill for immediate use.

Tradespeople needing a 33 mm cutter

Suited for electricians, plumbers, and general contractors who require a 33 mm hole saw with an integrated mandrel and pilot drill for metal, plastic, or wood. Not for users who need a different cutting diameter, a hole saw without a mandrel, or blades sized for the EZE Slot plug removal feature which applies to diameters of 1 3/4 in (45 mm) and larger. California Proposition 65 warnings apply regarding cancer and reproductive harm.

33 mm cutting diameter

The single specification that decides fit is the 33 mm cutting diameter, which must match the required hole size for the application. The included screw-in mandrel and pilot drill are sized for this diameter. Verify the 33 mm dimension against project requirements before purchase.

Questions about this item

What does the 1 5/16-inch diameter mean when the hole saw is mounted on a drill?

It produces a finished hole 33 mm across in metal, plastic or wood when the bi-metal blade is driven by the included mandrel.

How does the screw-in mandrel connect to the hole saw and what does that limit?

The mandrel threads into the hole saw body and locks the pilot drill in place, so the assembly only fits drills that accept its shank size.

What physical clearance is needed for the pilot drill and mandrel assembly?

The pilot drill extends beyond the tooth tips, so the workpiece must be thick enough to let the point engage before the teeth contact the surface.
