Hole saw bi-metal M.K. Morse Advanced Bi-Metal 64 mm (2-1/2")

Bi-metal hole saw M.K. Morse Advanced Bi-Metal 64 mm (2-1/2") is designed to cut precise circular openings in metal and a range of other materials. The tool combines high-speed steel cutting edges welded to a flexible alloy body to provide a balance of cutting performance and durability. It is compatible with standard drill chucks and drill presses and is intended for contractors, tradespeople and workshop use where reliable round cutouts are required.

Advantages

The bi-metal construction delivers increased wear resistance and maintains sharpness through repetitive cutting, while the robust body reduces the risk of deformation under load. Teeth geometry is optimized for cutting through ferrous and non-ferrous metals as well as softer construction materials, providing clean edges and reducing the need for secondary finishing. The saw's size and compatibility with common arbors make it a versatile option for field and shop work.

Suitable for

• Cutting circular holes in sheet metal, steel pipes and metal panels
• Creating openings for plumbing fixtures, conduit and HVAC ducts
• Electrical installations requiring accurate round cutouts for boxes and fittings
• General metalworking and maintenance tasks in workshops and job sites

Key specifications

• Diameter: 64 mm (2-1/2")
• Material: bi-metal (HSS teeth fused to flexible alloy body)
• Compatibility: standard drill chucks and drill presses with appropriate arbor
• Intended cutting materials: ferrous metals, non-ferrous metals, and softer construction materials
• Design: optimized tooth geometry for fast, clean cuts

How to use

Fit the hole saw to a compatible arbor and secure it in the drill chuck or press spindle. Mark the center of the required hole and, if possible, use a center punch to prevent wandering. Start drilling at low speed to establish the pilot position, then increase speed and apply steady pressure while allowing the saw to cut without forcing. Use cutting fluid for metal work to extend tool life and improve cut quality. After cutting, remove any burrs with a file or deburring tool if necessary.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Match drill speed and feed to the material being cut: lower speeds for harder metals, higher speeds for softer materials. Maintain sharpness by avoiding excessive heat buildup and by using suitable cutting lubricant when working with metals.
