Hole Saw Set AWTools Black Line 15-piece bimetal 19–76 mm with metal case

AWTools Black Line 15-piece bimetal hole saw set covers diameters from 19 mm to 76 mm and is supplied in a durable metal case. The set is designed for cutting circular holes in wood, metal and plastic. Bimetal construction combines a high-speed steel cutting edge with a flexible alloy backing to improve durability and increase edge life. The kit contains a range of commonly used diameters and fits standard mandrels for use with electric drills and drill drivers.

Advantages

The bimetal design provides enhanced wear resistance and longer service life compared with carbon-steel hole saws. Teeth are sized and spaced to facilitate efficient cutting across different materials while reducing vibration. The included metal case keeps all components organized and protected during transport and storage. Compatibility with standard mandrels makes the set convenient to use with a wide range of cordless and corded drills.

Suitable for

• Creating holes for plumbing fittings and pipe penetrations
• Installing electrical boxes and cable entry points
• Cutting openings in wood workpieces, plastic panels and thin metal sheets
• General installation, repair and maintenance tasks that require circular cutouts

How to use

Select the hole saw diameter required for the application, secure the appropriate mandrel in the drill chuck, and attach the hole saw to the mandrel according to the mandrel instructions. Mark the centre point of the hole on the workpiece and, when possible, use a pilot bit or guide to ensure accurate positioning. Operate the drill at a moderate speed and apply steady pressure; allow the saw teeth to cut without forcing. For metal cutting, use cutting fluid or coolant and remove chips frequently. After completing the cut, clear the hole saw of debris and inspect the teeth for wear before the next use.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Match cutting speed and feed to the material: lower speeds for metal, higher speeds for wood and plastic. Keep the hole saws clean and store them in the provided metal case to maximise service life.
