Hole saw AWTools AW49520 — compact drill accessory, weight 36 g

AWTools AW49520 is a compact hole saw designed as a drill accessory for creating clean circular openings. The tool weighs 36 g and features a body made of alloy steel with a powder-coated finish and cutting teeth made of HSS M3 bi‑metal steel that are laser welded for durability. Its progressive tooth pitch promotes fast, precise drilling and efficient chip removal, and it is compatible with standard electric drills and impact drills.

Advantages

The compact and lightweight design reduces operator fatigue and simplifies handling in confined spaces. Laser‑welded HSS M3 bi‑metal teeth combine wear resistance and toughness for cutting a variety of materials. Progressive tooth pitch improves cutting speed and chip evacuation, while the powder‑coated alloy steel body resists corrosion and mechanical wear. Compatibility with standard electric and impact drills makes the accessory versatile for many on‑site tasks.

Suitable for

• Creating through holes for ventilation ducts and conduit entry
• Making openings for sanitary and plumbing pipes
• Cutting holes for electrical junction boxes and socket boxes
• Drilling holes for lock sets and hardware installation
• Preparing circular openings for LED fixtures and lighting installations

How to use

Secure the AWTools AW49520 hole saw to a compatible arbor or mandrel following the drill and arbor manufacturer's instructions. Mark the centre point of the intended hole, clamp the workpiece if possible, and set the drill to an appropriate speed for the material being cut. Start drilling with steady, even pressure and allow the progressive teeth to cut while chips evacuate. For metal and harder materials, reduce speed and avoid excessive axial force to prevent overheating. After cutting, retract the hole saw and clear any chips before finishing the edge as required.

Usage recommendations

Use appropriate personal protective equipment including safety glasses and gloves. For long cuts or hard materials, apply cutting lubricant when drilling metals and periodically withdraw the saw to clear chips. Secure thin or fragile panels to prevent vibration and ensure a stable cut. Follow drill and accessory safety guidelines to extend tool life and maintain cutting performance.
