RICHELIEU 988231 16-Piece Bi-Metal Hole Saw Set 19-64 mm

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.
