Hole saw (bi-metal) Verto 22 mm 60H924

The Verto bi-metal hole saw 22 mm is a cutting accessory designed to create clean 22 mm diameter holes in metal and a range of other materials. Constructed from bi-metal, the tool combines a high-speed steel tooth edge with a flexible alloy body to improve wear resistance and reduce breakage under heat and mechanical stress. It is intended for use with compatible drills and drivers and is suitable for tasks in metalworking, HVAC, plumbing, electrical installations and general workshop use where precise round cuts are required.

Advantages

Bi-metal construction provides extended durability and better heat resistance compared with conventional carbon steel hole saws. The 22 mm diameter delivers consistent, accurately sized holes while the tooth geometry is optimized for efficient chip evacuation and reduced clogging. The saw is compatible with standard drill arbors and quick-change adaptors, offering convenient mounting and reliable concentric cutting. Its balanced design helps minimize vibration and improves surface finish of the cut.

Suitable for

• Cutting holes in thin and medium-thickness metal sheets
• Creating openings for pipes and conduits in HVAC and plumbing installations
• Drilling round access ports for electrical boxes and cable routing
• General workshop tasks requiring precise 22 mm round holes in various materials

Key specifications

• Cutting diameter: 22 mm
• Material: bi-metal (high-speed steel teeth with flexible alloy body)
• Intended materials: metal sheets, non-ferrous metals, some plastics and composite materials
• Compatibility: fits standard drill chucks and compatible arbors/adaptors
• Typical applications: metalworking, HVAC, plumbing, electrical installation, workshop use

How to use

Secure the appropriate arbor or adaptor in the drill chuck, then mount the hole saw onto the arbor according to the arbor manufacturer’s instructions. Mark the center point of the hole and use a pilot drill or center punch to prevent wandering. Operate the drill at the recommended speed for the material being cut, applying steady pressure without forcing the saw. For metalwork, use cutting fluid or lubricant to reduce heat and extend tool life. After cutting, remove burrs from the hole edge as needed.

Usage recommendations

For best results when cutting metal, use a moderate drill speed, apply cutting lubricant, and allow the saw to cool between long cuts. Ensure the workpiece is securely clamped and take appropriate safety precautions such as eye protection and gloves.
