Morse MHSA30C Bi-Metal Hole Saw 1-7/8" 48mm

SKU CH-BWBQ-25HG8

Arbored bi-metal hole saw cuts 48 mm holes in stainless steel, metal, wood and plastic with aggressive positive-rake teeth and a side slot for easy slug removal

  • Bi-metal construction handles stainless steel and wood
  • Positive rake teeth penetrate material faster
  • Side slot design eases slug removal
  • Arborged design ready for immediate use

Application scope

The Morse MHSA30C is a 1-7/8 inch bi-metal hole saw built for general-purpose cutting across stainless steel, machinable metals, wood and plastic. Its positive rake tooth profile is engineered to penetrate these materials faster and with less effort. Tradespeople needing a single, versatile cutter for mixed-material jobs will find it suited to the task. It is not intended for buyers who require carbide-tipped teeth for abrasive materials or very large diameter cuts.

Design impact

The unique side slot provides extra leverage access, making slug removal easier across various material thicknesses. The saw is supplied arbored on a single card, so it is ready to mount without a separate arbor purchase. Morse highlights CUTLUBE 121408 as a performance optimiser, though the lubricant itself is not included in the package. Users who prefer to run dry or with their own coolant can still operate the saw normally.

System limits

The 48 mm cutting diameter fixes the maximum hole size this tool can produce, so larger openings will require a different saw. As a bi-metal construction, it handles heat and wear better than high-speed steel alone but will dull faster than carbide when used heavily on stainless steel. The tool has no sales restrictions in any listed state, meaning it can be shipped and used without regulatory limitation.

Questions about this item

When should the Morse MHSA30C bi-metal hole saw be replaced?

Replace the hole saw when the bi-metal teeth become dull or damaged and no longer cut cleanly through stainless steel, machinable metals, wood or plastic.

What limits cutting depth with the Morse MHSA30C during extended use?

The 48 mm diameter and built-in arbor determine the maximum hole size and depth of cut in a single pass.

How much heat does the Morse MHSA30C generate when running all day?

The aggressive positive-rake tooth profile reduces friction, while the side slot improves chip ejection to keep the cut cooler during prolonged drilling.
