The MK MORSE mhs10 is a 5/8-inch (16mm) Advanced Bi-Metal Hole Saw built for professional cutting applications in metal, wood, and multi-material substrates. It features a heavy-duty 0.050-inch side wall for increased rigidity and durability under demanding load cycles, and delivers a cutting depth of 1-15/16 inches. The saw ships without an arbor, making it compatible with separately selected arbor systems. Manufactured in the USA, this hole saw consolidates the performance characteristics of multiple bi-metal lines into a single, streamlined design suited for electricians, plumbers, HVAC techs, and general contractors.
The mhs10 is intended for trade professionals who require consistent, clean cuts in repetitive or high-volume applications. Its 5/8-inch diameter makes it well-suited for smaller conduit knockouts, pipe penetrations, and similar trade work where precision bore size matters. The no-arbor configuration allows the installer to pair it with a compatible arbor already on hand, reducing redundancy in a tool kit. This saw is appropriate for both residential and light commercial jobsite use.
Designed for use with a separately purchased compatible arbor. Fits standard bi-metal hole saw arbor systems accepting 5/8-inch hole saws. Consult arbor manufacturer specifications for thread and shank compatibility before installation.
Installation should be performed by a qualified tradesperson familiar with rotary cutting tools and applicable jobsite safety requirements. Ensure the drill or hole saw driver is powered off and unplugged before mounting the saw to the arbor. Secure the arbor connection fully before operation and confirm the workpiece is clamped or otherwise stabilized. Eye protection and appropriate PPE are required during use.
