Hole saw bi-metal Verto 67 mm model 60H939

The Verto bi-metal hole saw 67 mm (model 60H939) is a circular cutting tool engineered to create clean, precise 67 mm diameter openings in a variety of construction and industrial materials. Its bi-metal cutting edge combines high-speed steel and flexible alloy substrate to deliver improved wear resistance and higher thermal tolerance compared with standard carbon-steel saws. The saw is designed for use with compatible arbors and drills where a stable, accurately sized hole is required.

Advantages

The bi-metal construction provides a balance of hardness and toughness that extends blade life during repeated cutting operations. Precision-machined teeth ensure consistent cutting performance and reduce the need for secondary finishing. The saw's design improves heat dissipation during continuous work, reducing the risk of premature tooth failure. It is suitable for both hand-held and machine-mounted drilling setups, offering versatility across trades.

Suitable for

• Cutting 67 mm diameter openings in thin to medium-thickness sheet metal
• Creating holes in non-ferrous metals and metal ducts for HVAC installations
• Drilling holes in timber, plastic, and composite panels where a 67 mm aperture is required
• Professional maintenance and repair tasks requiring repeatable hole sizes

Key specifications

• Cutting diameter: 67 mm
• Material: bi-metal cutting edge (high-speed steel teeth bonded to flexible alloy body)
• Intended use: metalworking, construction, HVAC, general-purpose drilling
• Compatibility: for use with standard hole saw arbors and drills capable of accepting this size
• Cut type: circular through-holes in sheet and panel materials

How to use

Select a compatible arbor and secure the hole saw to the drill spindle following the arbor manufacturer's instructions. Mark the center of the required 67 mm opening and, if available, use a pilot drill to guide the hole saw and improve centring. Begin drilling at low speed to establish contact, apply steady pressure, and maintain a perpendicular angle to the workpiece. For metal applications use cutting lubricant to reduce heat and extend saw life. After cutting, remove burrs or sharp edges as required.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. When cutting metal, moderate cutting speeds and suitable lubricants improve tool life. For thicker or harder materials consider progressive cutting or multiple passes rather than forcing the saw in a single pass.
