3-1/8" Bi-Metal Hole Saw

The Morse MHSA50C is a 79 mm diameter arbored hole saw built from bi-metal for general-purpose cutting. It handles stainless steel, machinable metals, wood and plastic in a single tool. One saw is supplied per card for immediate job-site use.

Positive Rake Tooth Profile

Aggressive positive rake teeth penetrate material faster and with less effort than standard profiles. A unique side slot improves leverage access across various material thicknesses and eases slug removal. Morse CUTLUBE 121408 is recommended to optimise cutting performance.

79 mm Fixed Diameter

This saw cuts only a 3-1/8 inch hole; it cannot be adjusted or swapped for other sizes. Buyers who need different diameters or a non-arbored configuration must select another product.
