RICHELIEU 961721 64 mm Bi-Metal Hole Saw

The RICHELIEU 961721 is a 64 mm bi-metal hole saw supplied with a screw-in mandrel and pilot drill. 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 enables efficient cutting of metal, plastic and wood. The EZE Slot allows quick plug removal on this diameter.

Who this suits and who should look elsewhere

This hole saw suits tradespeople and DIY users drilling clean holes in metal, plastic or wood with a single tool. The included mandrel and pilot drill mean it is ready to use immediately. Buyers needing diameters smaller than 45 mm cannot use the EZE Slot for plug ejection. Users requiring carbide-tipped teeth for abrasive materials such as tile or cast iron should select a different saw type.

64 mm cutting diameter

The 64 mm diameter determines the maximum hole size this saw produces. It also qualifies the blade for the EZE Slot plug-removal feature, which is only present on diameters of 45 mm and larger. Verify that your project requires this exact hole size before purchasing.

Questions about this item

How do I confirm the 64 mm bi-metal hole saw is cutting correctly after attaching the mandrel and pilot?

The saw should produce clean, steady cuts in metal, plastic or wood without vibration; the 4/6 variable tooth pitch and electron-beam-welded M3 teeth maintain consistent hardness, while the heavy-duty backing plate keeps the blade rigid.

Which components come in the box and what must I supply separately?

The package includes the 64 mm bi-metal hole saw, a screw-in mandrel and a pilot drill; you only need to provide a compatible power drill or drill press.

Should I choose this 64 mm version or the 45 mm size for my project?

Select the 64 mm (2 1/2 in) saw when the hole diameter must be 64 mm; the 45 mm version is for smaller holes and both share the same bi-metal construction, variable tooth pitch and EZE Slot for plug removal.
