Hole saw AWTools AW49570 — lightweight 220 g cutting tool

AWTools AW49570 — lightweight 220 g cutting tool is a bi-metal hole saw designed to create precise circular cutouts for a wide range of installation and maintenance tasks. The body is made of alloy steel with a powder-coated finish, while the cutting teeth are manufactured from HSS M3 bi-metal steel and laser welded to the body. With a compact, lightweight construction and progressive tooth pitch, this hole saw delivers efficient chip removal and fast, accurate drilling when used with compatible drills and arbors.

Advantages

The laser-welded HSS M3 bi-metal teeth provide improved wear resistance compared with simple carbon steel teeth, and the progressive tooth pitch ensures smooth cutting and quick material clearance. The alloy steel body with powder coating increases corrosion resistance and durability without adding unnecessary weight, keeping the total tool mass at approximately 220 g. The design is compatible with standard electric and impact drills, offering practical versatility for trade and DIY applications.

Suitable for

• Creating through holes for ventilation ducts and HVAC fittings
• Cutting holes for sanitary and plumbing pipes
• Installing junction boxes, socket boxes and lock sets
• Drilling openings for LED lighting and electrical fixtures
• Making precision circular cutouts in wood, metals and plastics

Key specifications

• Construction: alloy steel body with powder-coated finish
• Cutting material: HSS M3 bi-metal teeth, laser welded
• Tooth geometry: progressive tooth pitch for efficient chip evacuation
• Weight: approximately 220 g
• Compatible machines: standard electric drills and impact drills
• Usable materials: steel, cast iron, wood and wood-based materials, aluminum and non-ferrous metals, plastics, acrylic glass, plasterboard

How to use

Secure the hole saw on a compatible arbor and attach it to a standard electric or impact drill. Mark the centre of the required hole and, if available, use a pilot bit to guide the saw for improved accuracy. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material being cut while maintaining steady pressure. Allow the saw to cut through the material without forcing; periodically withdraw to clear chips and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves, dust mask) and clamp or secure the workpiece before drilling. For metals, apply cutting fluid or lubricant to extend tool life and improve cutting performance. For brittle materials such as acrylic glass or plasterboard, reduce speed and use light steady pressure to avoid chipping. Inspect the drill and arbor connection regularly and replace the hole saw if teeth show significant wear or damage.
