Hole saw AWTools AW49548 — lightweight 110 g cutting accessory

AWTools AW49548 — lightweight 110 g cutting accessory is a bi-metal hole saw designed for creating precise circular cutouts with standard electric or impact drills. The body is made of alloy steel with a powder-coated finish for corrosion resistance, while cutting teeth are HSS M3 bi-metal steel and laser welded for improved edge strength. Progressive tooth pitch supports fast, precise drilling and efficient chip evacuation, making this hole saw suitable for a wide range of materials commonly encountered in carpentry, installation and repair work.

Advantages

The lightweight construction (110 g) reduces operator fatigue and improves balance when used with hand-held drills. Laser-welded HSS M3 cutting teeth provide long-lasting cutting performance across various materials. The alloy steel body with powder coating increases durability and reduces the risk of surface corrosion. Progressive tooth pitch enhances cutting speed and chip removal for cleaner, more consistent holes.

Suitable for

• Cutting through wood and wood-based panels
• Making openings in plasterboard and drywall
• Cutting holes in plastics and acrylics
• Drilling through non-ferrous metals such as aluminum
• Creating through holes in thin steel and cast iron where appropriate
• Installing ventilation ducts, plumbing pipes, junction and socket boxes, lock sets, and LED fixtures

Key specifications

• Compatibility: designed for use with standard electric and impact drills
• Weight: approximately 110 g
• Application: wood, plasterboard, plastics, acrylic glass, aluminum, non-ferrous metals, thin steel and cast iron

How to use

Attach the hole saw to a compatible arbor or directly to the drill chuck according to the drill and arbor manufacturer instructions, ensuring a secure fit. Mark the center of the desired hole and, if available, use a pilot bit or arbor pilot to maintain position. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material while applying steady, moderate pressure. Use cooling or intermittent cutting pauses when working on metals to reduce heat build-up and prolong cutting edge life. After cutting, remove burrs and clean the hole as needed.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For metal cutting, apply cutting fluid or perform periodic breaks to prevent overheating. Secure workpieces firmly and avoid excessive side load on the hole saw to prevent wobbling. Verify drill speed and feed for each material: slower speeds for metals, higher speeds for wood and plastics.
