Hole saw bimetal Abraboro HSS-CO 60 x 38 mm AB30060000

Hole saw bimetal Abraboro HSS-CO 60 x 38 mm is designed for cutting precise circular openings in metal and a range of other materials. Manufactured from high-speed steel with added cobalt, this bimetal construction improves wear resistance and heat tolerance for repetitive or demanding cutting tasks. The 60 mm diameter and 38 mm cutting depth make it suitable for creating holes for pipes, conduits, fittings and mounting hardware when used with a compatible arbor and drill.

Advantages

The Abraboro HSS-CO bimetal composition combines a durable cutting edge with a flexible backing to resist chipping and extend tool life. Cobalt alloying increases hardness at elevated temperatures, maintaining cutting performance under heavier loads. The 60 mm cutting diameter provides a standard size for many installation tasks while the 38 mm depth allows through-holes or recesses in thin-to-medium material thicknesses. Teeth geometry and bimetal bond deliver efficient chip evacuation and reduced clogging during continuous work.

Suitable for

• Cutting circular holes in sheet metal, steel and stainless steel
• Creating openings for plumbing pipes and conduits
• Installing electrical boxes, fittings and ventilation components
• General maintenance, retrofit and fabrication where a 60 mm hole is required

Key specifications

• Material: high-speed steel with cobalt (HSS-CO)
• Cutting diameter: 60 mm
• Cutting depth: 38 mm
• Design: bimetal construction for improved durability
• Compatibility: requires a compatible arbor and drill with appropriate speed and torque

How to use

Mount the hole saw onto a compatible arbor that fits your drill and secure the pilot drill if present. Select a drill with adequate torque and set a moderate speed appropriate for metal cutting; use cutting fluid to reduce heat and prolong tool life. Align the pilot drill at the intended center point, apply steady pressure and allow the saw to cut without forcing. Withdraw periodically to clear chips and reapply cutting fluid as needed. After completing the hole, deburr edges with a suitable file or deburring tool.

Usage recommendations

Use appropriate personal protective equipment, clamp the workpiece securely, and match drill speed and feed to the material. For thicker or hardened metals, reduce speed and maintain cooling to prevent premature wear of the hole saw.
