## Summary description

Irwin 33 mm hole saw with TCT/HM (tungsten carbide) cutting edge designed for cutting through bricks, hollow blocks and aerated concrete. Supplied without an adapter, it fits hole saw arbors that accept 33 mm diameter cups. Intended for masonry drilling tasks such as installing pipes, conduits and anchors in construction and renovation work.

## Long description

Irwin 33 mm hole saw with a tungsten carbide (TCT/HM) cutting edge is designed for drilling clean circular openings in masonry materials such as bricks, hollow blocks and aerated concrete. Supplied without an adapter, the cup has a 33 mm outer diameter and is intended for use with compatible arbors that accept 33 mm hole saw cups. This tool is intended for construction and renovation tasks where reliable, durable cutting in masonry is required for installing pipes, conduits and anchors.
Advantages
The TCT/HM cutting edge provides high wear resistance and extended life compared with standard bi-metal cups when working with abrasive masonry. The 33 mm diameter offers a precise, consistent hole size for small-diameter service penetrations. Designed for masonry applications, the cup geometry and carbide teeth maintain cutting performance in porous materials like aerated concrete and in denser bricks. Supplied without an adapter, the hole saw remains compatible with a wide range of arbors that accept the 33 mm cup size.
Suitable for
Drilling circular openings in bricks for pipe and conduit installation
Creating holes in hollow blocks for anchor or sleeve placement
Cutting through aerated concrete for service penetrations and cable entries
On-site construction and renovation masonry drilling where a compact hole is required
Key specifications
Cutting edge material: tungsten carbide (TCT/HM)
Cup diameter: 33 mm
Intended material: brick, hollow block, aerated concrete
Supply condition: hole saw only (no arbor/adapter included)
Typical use: rotary drilling in masonry with compatible arbor
How to use
Fit the 33 mm hole saw onto a compatible arbor that accepts this cup diameter and secure according to the arbor manufacturer's instructions. Use a rotary drill with sufficient torque and, where possible, a pilot bit to guide the cup. Start drilling at low speed to establish the position, then apply steady pressure and moderate speed; avoid excessive force that can damage the carbide teeth or cause the cup to bind. For aerated or fragile masonry, reduce speed and feed to avoid cracking. Clear debris from the cutting area periodically to maintain cutting efficiency.
Usage recommendations
Wear appropriate personal protective equipment including eye protection, gloves and a dust mask. Use a drill with an appropriate arbor that securely fits the 33 mm cup and is rated for masonry use. For best life and performance, keep the cutting area clear of loose debris and avoid overheating by using intermittent drilling and light lubrication or water only if the arbor and drill permit wet use. Inspect the carbide teeth regularly and replace the cup when wear reduces cutting performance.
