Morse MHS23M Hole Saw Kit 20-piece pneumatic accessory

SKU CH-BFNG-RGPA3

A 20-piece bi-metal hole saw kit covering 3/4 in to 4-3/4 in for general-purpose cutting of duct, mild steel, nail-embedded wood, non-ferrous metals, pipe, plastic.

  • 20-piece kit covers a wide range of hole diameters
  • Bi-metal teeth cut steel, stainless, wood, plastic and non-ferrous metals
  • Built-in arbor design simplifies bit changes on the job
  • 1 7/8 in cutting depth handles thick pipe and duct work
  • 5/6 variable tooth pitch reduces vibration for smoother cuts

Kit Contents and Purpose

The Morse MHS23M kit supplies twenty bi-metal hole saws ranging from 3/4 in to 4-3/4 in. It targets maintenance crews and fabricators who need a single set for general-purpose cutting across multiple materials.

Built-In Arbor Benefit

Each saw integrates its own arbor so there is no separate pilot bit to swap or lose. The 5/6 variable tooth pitch clears chips efficiently in duct, mild steel, nail-embedded wood, non-ferrous metals, pipe, plastic, stainless steel and tube.

Maximum Cutting Depth

A 1 7/8 in depth of cut lets the saws penetrate thick-walled pipe and structural sections in one pass. The tools are not impact rated, so they must be used with standard rotary drills rather than percussion drivers.

Questions about this item

When will the bi-metal teeth on the 20 hole saws need replacement?

The bi-metal teeth will need replacement once they become dull from cutting stainless steel, mild steel, or nail-embedded wood, which reduces cutting speed and increases heat buildup.

What stops continuous cutting first when working through 1 7/8 in thick stainless steel pipe?

Heat buildup in the bi-metal teeth and arbor limits sustained cutting in thick stainless steel, requiring pauses to let the saw cool and maintain tooth integrity.

How much heat and vibration does the built-in arbor generate during all-day use on duct and pipe?

The built-in arbor transfers vibration directly to the drill, and bi-metal teeth generate noticeable heat when cutting stainless steel or thick pipe continuously.
