RICHELIEU 988231 16-Piece Bi-Metal Hole Saw Set
This 16-piece bi-metal hole saw set from RICHELIEU covers diameters from 19 mm to 64 mm. It is built for trade professionals and serious DIYers who need to cut clean holes in metal, plastic, and wood. The M3 high-speed steel teeth are electron-beam welded to a heavy-duty backing plate for rigidity and consistent hardness. A 4/6 variable tooth pitch supports efficient cutting across mixed materials.
Suited for mixed-material cutting up to 64 mm
The set suits electricians, plumbers, and general contractors drilling pipe and conduit entries in sheet metal, plastic boxes, and timber studs. It is not intended for users who only need a single size or who require carbide-grit edges for abrasive materials such as tile, stone, or cast iron. Buyers needing diameters larger than 64 mm or a dedicated arbor system not included here should look at other kits.
Standard arbor fit with EZE Slot plug ejection
Each saw mounts on a standard arbor shank and the EZE Slot feature on blades 45 mm and larger gives leverage for quick plug removal. The 51 mm cutting depth lets you cut through 102 mm timber in one pass. The most common issue is forgetting to lubricate when cutting metal, which dulls the M3 teeth prematurely. Ensure the arbor is fully seated and the pilot drill is sharp to avoid walking.

Questions about this item
What power-tool chuck size do I need to run the 19 mm to 64 mm bi-metal hole saws?
The set uses standard arbors that fit a 1/2 in (13 mm) drill chuck, so a drill with at least that capacity is required.
Will the 4/6 variable tooth pitch cut cleanly through the 51 mm thick 2×4 lumber I already use?
Yes, the 45 mm cutting depth lets you bore through a 51 mm × 102 mm board in a single pass on wood, plastic or metal.
How can I verify the EZE Slot is ejecting plugs correctly after the first few holes?
On saws 45 mm and larger the slot should lever the slug out automatically; if the plug stays stuck, the slot may be clogged or the saw dull.
