Hole saw bimetal Abraboro HSS‑Co 83 x 38 mm AB30083000

The Abraboro Hole saw bimetal HSS‑Co 83 x 38 mm is a precision cutting tool designed to create clean round holes with an 83 mm diameter and a cutting depth of 38 mm. Constructed from high‑speed steel with cobalt alloy, this hole saw delivers improved heat resistance and edge life compared with plain HSS, making it suitable for demanding metalworking tasks. Intended for use with standard drill chucks or arbor attachments, it is compatible with typical drilling rigs used in fabrication and installation work.

Advantages

The bimetal HSS‑Co construction combines a high‑speed steel body with a cobalt‑enriched cutting edge to provide greater wear resistance and sustained cutting performance at elevated temperatures. The 83 mm diameter and 38 mm depth offer a balance between hole size and material thickness capacity, while the tooth geometry is optimized for efficient chip evacuation and reduced jamming. The tool is suitable for repetitive drilling operations in metal and mixed materials where a durable cutting edge is required.

Suitable for

• Cutting holes in steel sheets and metal plates
• Installing pipes, conduits and cable glands
• Creating access openings in HVAC and ducting work
• Drilling clearance holes in construction and fabrication tasks

Key specifications

• Cutting diameter: 83 mm
• Cutting depth: 38 mm
• Material: high‑speed steel with cobalt (HSS‑Co)
• Tooth type: bimetal teeth designed for metal cutting
• Compatible drive: standard drill/arbor mounting

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 and, if available, use a pilot drill to ensure accurate positioning. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material and drill capacity. Apply steady feed pressure and back off periodically to clear chips and prevent overheating. Use cutting fluid or coolant when working with thicker or harder metals to extend tool life.

Usage recommendations

For best results, use the Abraboro HSS‑Co hole saw with a drill that provides stable rotational speed and sufficient torque. Maintain moderate cutting speeds for steel and apply cutting fluid during prolonged cuts. Inspect the teeth for wear before repetitive jobs and replace the tool if cutting performance deteriorates.
