Morse MHSA44C 2.75" Bi-Metal Hole Saw

The Morse MHSA44C is a 2.75 inch (70 mm) diameter bi-metal hole saw designed for general-purpose cutting. It handles stainless steel, machinable metals, wood and plastic with an aggressive positive rake tooth profile for faster penetration. The arbored design includes a unique side slot that improves leverage and eases slug removal. One hole saw is supplied per card.

Compatibility checks before ordering

Verify that your drill chuck accepts the arbor shank size and that the tool provides suitable speed control for the material you intend to cut. Ensure the workpiece thickness matches the cutting depth of the saw and that you have appropriate lubrication such as Morse CUTLUBE 121408 to optimise performance and extend tool life.

Who this suits and who should look elsewhere

This hole saw suits tradespeople and DIY users needing a single 2.75 inch cutter for mixed materials in maintenance, fabrication or installation work. It is not for buyers who need multiple diameters in one kit, those requiring carbide-tipped teeth for abrasive materials, or users who need a quick-change system for rapid size swaps.

Questions about this item

Does the MHSA44C come with a pilot drill or do I need to buy one separately?

The MHSA44C is an arbored hole saw, so the pilot drill is built into the arbor and no separate pilot bit is required.

What does the 2.75 inch diameter mean for the actual hole I will cut?

The saw cuts a 2.75 inch (70 mm) diameter hole, suitable for 2 inch conduit knockouts and similar openings.

How does the bi-metal construction and positive rake tooth profile affect cutting speed in stainless steel?

The bi-metal body with aggressive positive rake teeth penetrates stainless steel and other machinable metals faster and with less feed pressure.
