Hole saw Abraboro HSS-Co bimetal 108 x 38 mm, model AB30108000

The Abraboro HSS-Co bimetal hole saw 108 x 38 mm is a precision cutting tool designed to create clean circular openings with a 108 mm diameter and 38 mm cutting depth. Constructed from high-speed steel with cobalt alloying, this hole saw delivers improved wear resistance and sustained cutting performance when working with a range of materials. It is intended for use with compatible arbors and drilling machines in metalworking, plumbing, electrical installation, and general workshop tasks that require reliable hole cutting.

Advantages

The bimetal construction combines flexible backing steel with a high-speed steel cutting edge enhanced by cobalt for increased heat and wear resistance. This results in longer tool life compared with standard high-speed steel saws and consistent cutting quality over multiple uses. The 108 mm diameter and 38 mm depth provide a balance between reach and stability, enabling through-holes or deep recesses in sheet metal, pipes, and other components. The design supports efficient chip evacuation and reduced binding when used with appropriate speeds and lubrication.

Suitable for

• Cutting round openings in steel sheets and thin-walled pipes
• Plumbing installations where pipe collars or access holes are required
• Electrical panel work and mounting holes for conduits and gland fittings
• General fabrication and repair in workshops and maintenance departments

Key specifications

• Material: bimetal with high-speed steel cutting edge with cobalt alloying
• Cutting diameter: 108 mm
• Cutting depth: 38 mm
• Construction: bimetal body for flexibility and hardened cutting teeth for wear resistance
• Intended use: drilling/cutting in metals and mixed materials compatible with HSS-Co

How to use

Secure an appropriate arbor or pilot drill shank that matches the saw and the drilling machine. Clamp the workpiece firmly to prevent movement and set the drill to an appropriate speed for HSS-Co tooling and the material being cut. Start drilling with light feed to establish a pilot and then apply steady pressure to advance the saw. Use cutting fluid on steel and other ferrous materials to reduce heat and improve tool life. Withdraw periodically to clear chips and inspect the cut. After completing the hole, deburr edges as required for a clean finish.

Usage recommendations

For best results, match drill speed and feed to the material thickness and hardness, use cutting fluid on ferrous metals, and ensure secure clamping of the workpiece. Replace or resharpen worn arbors and inspect the saw teeth before use to maintain safety and cutting quality.
