Hole saw AWTools AW47320 — model AW47320, portable metal/wood cutting drill accessory, weight 684 g

AWTools AW47320 hole saw set is a portable drill-mounted cutting accessory designed for creating clean circular openings in a range of building materials. The set includes six hole saws in commonly used diameters and accessories in a compact case, offering a practical solution for on-site and workshop jobs where round holes are required for pipes, cables or fixtures. Constructed from HCS tool steel with tungsten carbide grit on the cutting edges, the saws combine cutting strength with wear resistance and are compatible with standard drill chucks.

Advantages

The AWTools AW47320 set provides a selection of six diameters to cover multiple installation needs without changing tools, while the tungsten carbide grit coating improves durability when cutting abrasive materials. HCS tool steel core ensures structural stability and resistance to deformation under normal drilling loads. The included pilot drills and hex wrench simplify setup and centring, and the compact case keeps components organised for transport and storage. Rated for safe operation up to 1500 rpm, the set suits both handheld and bench-mounted drills.

How to use

Select the hole saw diameter appropriate for the required opening and mount the chosen saw onto the arbor with the pilot drill installed. Secure the arbor in the drill chuck and set the drill to a speed not exceeding 1500 rpm. Position the pilot drill at the marked centre of the hole, start drilling with steady, moderate pressure and allow the pilot to guide the hole saw. For tile, terracotta or ceramic, use light pressure and consider a slower feed to reduce chipping; for wood and metal use steady cutting and clear debris regularly. After cutting, remove the cup and clean any remaining material from the teeth and pilot.

Usage recommendations

For best results, use appropriate personal protective equipment (safety glasses, gloves and dust mask). When cutting brittle materials such as tile or ceramic, support the material and use reduced speed and light pressure to minimise chipping. For metal cutting, secure the workpiece and use cutting fluid if applicable. Do not exceed the recommended maximum speed of 1500 rpm.
