Hole saw AWTools AW49540 — lightweight 80 g cutting accessory

AWTools AW49540 — lightweight 80 g cutting accessory is a compact hole saw designed for use with electric and impact drills. Constructed with an alloy steel body and a powder-coated finish, the hole saw features laser-welded HSS M3 bi-metal cutting teeth and a progressive tooth pitch that supports fast, precise drilling and effective chip removal. With a total weight of approximately 80 g, this accessory is intended for light-duty tasks in trades, installations and repair work where a small, easy-to-handle hole cutter is required.

Advantages

The alloy steel body with powder coating offers resistance to wear and surface corrosion while keeping the tool lightweight for improved handling. Laser-welded HSS M3 bi-metal teeth combine toughness and cutting performance, extending cutting life compared with simple carbon-steel teeth. Progressive tooth pitch enhances cutting speed and chip evacuation, reducing binding and heat build-up during operation. The design is compatible with standard drill arbors and works with both electric and impact drills for versatile on-site use.

Suitable for

• Cutting through steel and cast iron for pipe and conduit installations
• Creating openings in wood, plywood and other wood-based panels for fixtures and fittings
• Making holes in aluminum, non-ferrous metals and plastics for mounting components
• Drilling apertures in acrylic glass and plasterboard for lighting, ventilation and electrical boxes

Key specifications

• Body material: alloy steel with powder-coated finish
• Cutting teeth: HSS M3 bi-metal, laser welded
• Cutting geometry: progressive tooth pitch for fast cutting and efficient chip removal
• Compatible tools: standard electric drills and impact drills (with appropriate arbor)
• Typical applications: metal, wood, wood-based panels, aluminum, non-ferrous metals, plastics, acrylic glass, plasterboard
• Weight: approximately 80 g

How to use

Fit the AWTools AW49540 hole saw to a compatible arbor and secure it in the drill chuck according to the arbor manufacturer’s instructions. Mark the center of the desired hole and, if required, use a pilot bit or center punch to prevent wandering. Start drilling at low speed to establish the cut, then increase speed as needed while maintaining steady axial pressure. Allow the cutting teeth to do the work; avoid excessive force that can cause overheating or premature wear. Periodically clear chips from the hole saw to maintain efficient cutting and reduce heat accumulation.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For metal cutting, apply cutting lubricant to extend tooth life and reduce heat. When cutting brittle materials like acrylic or plasterboard, use lower speeds to prevent chipping. Ensure the drill and arbor are rated for the intended load and follow safe drilling practices.
