Hole saw AWTools AW49522 — lightweight 43 g cutting accessory for drills

AWTools AW49522 — lightweight 43 g cutting accessory for drills is a compact hole saw designed for making circular openings with standard electric or impact drills. Constructed with an alloy steel body and a powder-coated finish, and equipped with laser-welded HSS M3 bi-metal cutting teeth, this hole saw is optimized for fast and precise drilling and efficient chip evacuation. At 43 g it provides low inertia for easier handling and reduced load on the drill when producing through holes in a variety of common materials.

Advantages

The alloy steel body with powder coating ensures mechanical strength and corrosion resistance while keeping the tool lightweight. Laser-welded HSS M3 bi-metal teeth provide durability and maintain cutting performance across multiple materials. Progressive tooth pitch improves cutting speed and chip removal, resulting in cleaner holes and reduced risk of overheating. Compatibility with standard electric and impact drills makes the AWTools AW49522 versatile for on-site and workshop use.

Suitable for

• Cutting through steel and cast iron (thin to moderate thicknesses)
• Drilling holes in wood and wood-based panels
• Making openings in aluminum and other non-ferrous metals
• Creating holes in plastics and acrylic glass
• Installing ventilation ducts, sanitary and plumbing pipes
• Preparing openings for junction boxes, socket boxes and lock sets
• Drilling holes to fit LED lights and small fixtures

Key specifications

• Body material: alloy steel with powder-coated finish
• Cutting teeth: HSS M3 bi-metal, laser welded
• Weight: 43 g
• Tooth design: progressive pitch for fast cutting and efficient chip removal
• Drive compatibility: standard electric drills and impact drills
• Recommended materials: steel, cast iron, wood, wood-based materials, aluminum, non-ferrous metals, plastics, acrylic glass, plasterboard

How to use

Mount the hole saw onto an appropriate arbor or mandrel compatible with your drill, ensuring secure attachment before operation. Mark the center of the intended hole on the workpiece and position the pilot bit or arbor pilot to maintain alignment. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material while applying steady, moderate pressure. Use cutting lubricant when drilling metals to reduce heat and prolong tool life, and remove accumulated chips periodically to maintain cutting efficiency. After completing the hole, retract the hole saw and clear any remaining debris from the teeth.

Usage recommendations

Use personal protective equipment (safety glasses, gloves and hearing protection) and secure the workpiece before drilling. For metals, use cutting fluid and moderate feed to avoid overheating; for brittle materials such as acrylic glass or plasterboard, reduce speed and avoid excessive pressure to prevent cracking. Regularly inspect the cutting teeth for wear and replace the hole saw when cutting performance diminishes.
