Hole Saw Abraboro bimetal HSS-CO 40 x 38 mm, model AB30040000

The Abraboro bimetal hole saw HSS-CO 40 x 38 mm is designed for cutting precise circular openings in metal and a variety of other materials. Made from high-speed steel with added cobalt, this hole saw offers improved wear resistance and greater heat tolerance compared with standard HSS tools. With a 40 mm cutting diameter and 38 mm cutting depth, the tool is compatible with electric drills and drill presses and is suitable for installation, plumbing, HVAC and metalworking tasks that require reliable, repeatable hole cutting.

Advantages

The bimetal construction combines toughness and flexibility to reduce breakage and extend service life when cutting through sheet metal and harder materials. Cobalt-enriched HSS improves thermal stability at higher cutting speeds and helps maintain sharper cutting edges for longer. The specified cutting diameter and depth provide consistent hole geometry for fittings, conduit and pipe penetrations, while compatibility with standard drill arbors makes the saw easy to mount and use in workshop and site conditions.

Suitable for

• Cutting circular holes in sheet metal and thin steel
• Creating pass-throughs for pipes, cables and conduits
• HVAC ductwork and plumbing installations
• General metalworking and fabrication tasks

Key specifications

• Cutting diameter: 40 mm
• Cutting depth: 38 mm
• Material: high-speed steel with cobalt (HSS-CO)
• Construction: bimetal tooth design for wear resistance and toughness
• Compatibility: designed for use with electric drills and drill presses using standard arbors

How to use

Secure the hole saw to a compatible arbor and tighten according to the arbor manufacturer's instructions. Mark the centre point of the hole, clamp the workpiece securely and, if possible, use a pilot drill to guide the arbor. Operate the drill at a moderate speed, applying steady, even pressure and allowing the tool to cut without excessive force. For metal applications use cutting fluid or coolant to reduce heat and extend tool life. After cutting, remove burrs as needed and inspect the hole for accuracy.

Usage recommendations

For best results when cutting metal, use appropriate coolant, maintain moderate cutting speeds, and clamp the workpiece firmly. Replace the hole saw if teeth show significant wear or damage to ensure consistent hole quality and safe operation.
