## Long description

The M.K. Morse Advanced Bi‑Metal hole saw, 89 mm (3‑1/2") diameter, is engineered for cutting circular openings in metal and mixed materials. Its bi‑metal construction pairs high‑speed steel teeth with a flexible backing to provide a balance of cutting performance and resistance to heat and wear. The tool is suitable for creating precise holes in pipes, sheet metal, enclosures and panels where clean edges and long tool life are required.
Advantages
The bi‑metal design offers improved durability compared with standard carbon steel saws by combining a hard cutting edge with a tougher, shock‑resistant body. Heat resistance of the high‑speed steel teeth helps maintain cutting speed and edge life during continuous use. The 89 mm diameter provides a commonly used size for cable glands, conduit entries and larger access holes while the saw’s geometry promotes efficient chip evacuation and reduced binding.
Suitable for
Cutting circular holes in thin to medium‑thickness steel and non‑ferrous metals
Creating openings in electrical and instrumentation panels
Drilling access holes in plumbing pipes and metal conduit
Fabrication and maintenance tasks in workshops and construction sites
Key specifications
Diameter: 89 mm (3‑1/2")
Construction: bi‑metal (high‑speed steel teeth bonded to a flexible backing)
Intended materials: ferrous and non‑ferrous metals, mixed construction materials
Typical applications: metal cutting, panel and pipe openings
How to use
Select an appropriate arbor and pilot drill compatible with the hole saw and secure them to the drill. Mark the center of the intended hole, position the pilot bit, and start drilling at low speed to establish the center. Increase speed and apply steady, even pressure while allowing the saw to cut without forcing; use cutting lubricant when working with tougher metals to reduce heat buildup. After the cut is complete, reverse the drill slowly to remove the saw and clear any remaining material from the cut edge.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves) and clamp workpieces securely. For thicker or harder materials, use cutting fluid and run the drill at moderate speed to prolong tooth life. Inspect the saw before use for any damage and replace when teeth become dull to maintain clean cuts and safe operation.
