## Summary description

Irwin 73 mm hole saw with TCT/HM (tungsten carbide) cutting edge designed for cutting bricks, hollow blocks and aerated concrete. This accessory fits compatible drills and cores when used without an adapter; it is intended for masonry and lightweight concrete demolition, installation of pipes or conduit penetrations, and creating openings for fittings. Supplied without adapter.

## Long description

Irwin 73 mm hole saw with a TCT/HM (tungsten carbide) cutting edge is engineered for drilling clean openings in bricks, hollow blocks and aerated concrete. The tool is supplied without an adapter and is intended to be used with compatible drill spindles or core holders that accept arbor-free hole saws. Designed for on-site construction and renovation tasks, this hole saw delivers efficient material removal and maintains cutting performance in abrasive masonry materials.
Advantages
The TCT/HM cutting edge provides durable wear resistance and maintains sharpness longer than standard bi-metal teeth when working with brick and lightweight concrete. The 73 mm diameter offers a standard opening size for pipe entries and fittings, while the saw’s geometry promotes controlled chip evacuation and consistent hole quality. Supplied without an adapter, the product remains compact and ready for use with appropriate drill fittings.
Suitable for
Creating circular openings for pipes and conduit in brick walls
Cutting holes in hollow concrete blocks during installations
Drilling through aerated concrete for ventilation or service penetrations
Key specifications
Cutting edge: tungsten carbide-tipped (TCT/HM)
Diameter: 73 mm
Suitable materials: brick, hollow blocks, aerated concrete
Application: masonry and lightweight concrete drilling
Design: arbor-free configuration (supplied without adapter)
How to use
Select a drill or core holder that accepts arbor-free hole saws and ensure compatibility with the 73 mm body. Mark the drilling position, secure the workpiece or ensure stable access to the wall, and start drilling at low speed to establish the pilot contact. Apply steady, moderate pressure—avoid forcing the saw—to allow the TCT/HM teeth to cut efficiently and to reduce heat buildup. Periodically withdraw the saw to clear dust and debris, and use water cooling only if the base material and drill setup permit it.
Usage recommendations
Use appropriate personal protective equipment including eye protection, dust mask, and hearing protection. For reinforcement or very dense masonry, consider slower speeds and intermittent drilling to prolong cutting edge life. Verify drill spindle compatibility before use and, if an adapter is required, choose one rated for masonry hole saws.
