Hole saw Verto 67×55 mm tungsten carbide cutting teeth, model 60H908

Verto hole saw 67×55 mm (model 60H908) is a carbide-toothed hole cutter engineered for drilling circular openings in a range of construction and renovation materials compatible with tungsten carbide cutting edges. The tool features a 67 mm external diameter and a 55 mm cutting depth, with tungsten carbide (wolfram) teeth that increase resistance to wear and extend service life compared with standard bi-metal hole saws. It is intended for use with compatible drill/drivers and arbors for installing pipe penetrations, cable entries and other circular cutouts.

Advantages

The tungsten carbide cutting teeth provide improved hardness and abrasion resistance, allowing cleaner cuts and longer cutting life when working with abrasive or mixed materials. The robust body construction ensures stable cutting performance and reduces the risk of tooth loss under normal operating conditions. Compact dimensions and a defined cutting depth facilitate repeatable openings with consistent diameter and edge finish.

Suitable for

• Cutting circular openings in plasterboard and drywall where carbide-tipped saws are appropriate
• Drilling holes for pipe and conduit installations in renovation and light construction work
• Creating cable entry points in panels and thin building materials
• Work with mixed or mildly abrasive building materials that require enhanced tooth wear resistance

Key specifications

• Cutting diameter: 67 mm
• Maximum cutting depth: 55 mm
• Cutting teeth: tungsten carbide (wolfram) tipped for improved wear resistance
• Compatibility: designed for use with standard drill/drivers and appropriate arbors
• Body: hardened construction for dimensional stability during cutting

How to use

Select a suitable drill or driver and the correct arbor that matches the hole saw mounting. Secure the arbor in the drill chuck and fasten the hole saw to the arbor according to the arbor manufacturer’s instructions. Mark the centre of the desired hole on the workpiece, start the drill at low speed to create an initial guide, then increase speed and maintain steady pressure to cut through the material. Withdraw the saw periodically to clear chips and prevent overheating. After cutting, remove the cut core and inspect the teeth for wear before further use.

Usage recommendations

Use appropriate safety equipment including eye protection and gloves. Match rotation speed and feed pressure to the material being cut: lower speeds and moderate pressure for harder or more abrasive substrates. Do not apply excessive lateral force; allow the carbide teeth to cut progressively. Inspect the teeth regularly and replace the hole saw if teeth are damaged or excessively worn.
