Hole saw AWTools AW43425 — 1.6 kg, compatible with power drills

AWTools AW43425 hole saw is a cutting accessory designed for use with handheld and stationary power drills. Weighing 1.6 kg, this hole saw features a spiral core body and tungsten carbide teeth for cutting circular openings in masonry materials. The tool includes discharge holes and a pilot drill to aid chip removal and ensure a steady drilling start. It is suitable for impact or rotary drilling when installing pipes, cables or fittings that require a round aperture.

Advantages

The AWTools AW43425 combines a high-quality alloy steel body with tungsten carbide teeth to increase wear resistance during drilling into abrasive masonry. Its spiral core design reduces friction and promotes dust and chip evacuation through integrated discharge holes, improving cutting efficiency. Inclusion of a pilot drill helps centre the cut and reduces wandering at startup, while compatibility with impact and rotary drilling modes provides versatility for a range of drill types.

Suitable for

• Creating apertures for pipe and conduit installation in brick and concrete walls
• Drilling holes for electrical or plumbing fittings in masonry
• Trade and DIY projects requiring circular openings in block, breeze block or brick

How to use

Secure the hole saw to a compatible arbor and insert the pilot drill into the drill chuck. Mark the centre point of the required aperture on the work surface and position the pilot drill against that point. Start drilling at low speed to allow the pilot bit to engage and centre the saw, then increase speed as appropriate for the material and drill. Apply steady, even pressure; allow the tool to cut without forcing to prevent overheating. Periodically withdraw the saw to clear chips through the discharge holes and reduce friction. For deeper or larger cuts, make incremental passes rather than forcing a single deep cut.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, dust mask and hearing protection. When drilling masonry, use a drill with sufficient power and, where possible, a vacuum or dust extraction to manage debris. Cool the cutting edge by pausing between passes if excessive heat develops. Ensure the pilot drill is tight and the arbor is compatible with your drill for safe operation.
