The body is made of alloy steel with a powder-coated finish and the cutting teeth are manufactured from HSS M3 bi-metal steel and laser welded for durability. The tool features a progressive tooth pitch that supports fast and precise drilling and efficient chip removal. It is intended as a spare or replacement part and is compatible with standard electric and impact drills.

Advantages

The AWTools AW49529 combines an alloy steel body and HSS M3 bi-metal teeth, providing a balance of strength and wear resistance for a variety of substrates. Laser-welded teeth improve joint integrity and lifespan while the progressive tooth pitch speeds cutting and reduces clogging. The powder-coated finish increases corrosion resistance and makes handling and storage easier. At approximately 75 g, the unit is lightweight and suitable for use as a portable accessory with common drill setups.

How to use

Fit the AWTools AW49529 hole saw to a compatible arbor or mandrel and secure it to a standard electric drill or an impact drill according to the drill and arbor manufacturer’s instructions. Mark the drilling position on the workpiece, clamp the workpiece where possible, and start drilling at low speed to establish the cut. Increase speed gradually while maintaining steady pressure. For metal workpieces, use a cutting lubricant to reduce heat and extend tool life. Clear chips periodically to prevent clogging and ensure consistent cutting performance. After completing the hole, remove the saw and clean teeth and body before storage.

Usage recommendations

Use appropriate personal protective equipment including eye protection and gloves. Select proper drill speed and, when cutting metals, apply suitable cutting fluid. Ensure secure clamping of the workpiece and avoid side loads on the hole saw to prevent premature wear or damage to the tool.
