RICHELIEU 961481 54 mm Bi-Metal Hole Saw
This RICHELIEU 961481 is a 54 mm bi-metal hole saw supplied with a screw-in mandrel and pilot drill. It is built for tradespeople and serious DIY users who need to cut clean holes in metal, plastic or wood. The heavy-duty backing plate adds rigidity while the M3 high-speed steel teeth are electron beam welded for consistent hardness. A 4/6 variable tooth pitch helps the blade cut efficiently across those materials.
Suited for larger-diameter cuts
The saw diameter of 54 mm makes it appropriate for jobs requiring that specific size, such as conduit or pipe entries. The EZE Slot feature allows quick plug removal on blades of 45 mm and larger, so this model benefits from that convenience. Users who need smaller diameters or who prefer a hole saw without an included mandrel should look at other options. The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.
Simple mandrel fitment with a common snag
Installation is straightforward: thread the supplied mandrel into the saw, chuck the pilot drill and begin cutting. The most frequent issue is the mandrel loosening under vibration, so check it is fully tightened before each use. Another common problem is the pilot drill wandering on hard metal; a centre punch mark keeps it on track. The bi-metal construction resists tooth breakage but the blade will dull faster if run at excessive speed without lubrication.

Questions about this item
What size drill chuck is required for the mandrel included with the 54 mm hole saw?
The screw-in mandrel fits a standard drill chuck that accepts its shank diameter, allowing immediate use with most corded or cordless drills.
Will the 4/6 variable tooth pitch cut through the same mild steel plate I use with older bi-metal saws?
Yes, the M3 high-speed steel teeth and variable pitch are designed for efficient cutting of metal, plastic and wood, matching the materials your existing saws handle.
How do I know the EZE Slot is clearing the plug correctly after the first cut?
When the slot ejects the slug cleanly without binding, the saw is working as intended; the feature operates on all diameters 45 mm and larger.
