Hole saw MODECO MN-76-126 67 mm with tungsten grit cutting edge

MODECO MN-76-126 hole saw with a 67 mm cutting diameter and a tungsten grit cutting edge is designed to cut clean circular openings in materials that require an abrasive cutting surface. The grit edge with tungsten particles provides abrasive action rather than a tooth-based cut, making this hole saw suitable for hard, brittle, or coated materials where conventional tooth-cutting saws would be ineffective or prone to damage. The tool is intended for use with drills or drill rigs that accept standard hole saw attachments.

Advantages

The tungsten grit edge delivers controlled abrasive cutting that reduces chipping and cracking on fragile materials. The 67 mm diameter provides a common size for pipe and conduit penetrations. Constructed with a reinforced body and secure mounting interface, this hole saw maintains concentricity and stability during operation to produce consistent circular holes. Its abrasive cutting method allows work on a wider range of surfaces, including some ceramics, plastics, plaster, and thin metal coatings, where tooth-based hole saws may fail.

Suitable for

• Creating openings for pipes and electrical conduits
• Cutting ventilation and duct holes in renovation projects
• Drilling circular holes in plasterboard, gypsum, tile overlays, laminate and similar surfaces
• Making pass-throughs in fragile or coated materials where a grit edge reduces break-out

Key specifications

• Cutting diameter: 67 mm
• Cutting edge material: tungsten (tungsten grit / abrasive edge)
• Cutting method: abrasive grit edge (non-toothed)
• Compatibility: for use with drills and drill rigs that accept standard hole saw mounts
• Typical applications: construction, renovation, HVAC and electrical installations

How to use

Secure the hole saw to an appropriate arbor or mandrel that fits your drill or drill rig, ensuring the connection is tight and concentric. Mark the center of the intended opening, then start drilling at low speed to establish a guide and prevent wandering. Apply steady, moderate pressure and keep the drill speed appropriate for the material being cut; aggressive speed or force can overheat the grit or cause excessive wear. If cutting masonry, tile or similar materials, periodically withdraw to clear debris and allow cooling. For large or thick materials, consider pilot drilling or step cuts as required by the substrate.

Usage recommendations

Use personal protective equipment such as safety glasses, a dust mask and hearing protection. For ceramic tiles, stone or masonry, use water cooling or intermittent cutting to reduce dust and extend the life of the tungsten grit edge. Avoid applying lateral force; keep the drill aligned with the hole axis to prevent uneven wear and premature damage to the abrasive edge.
