Hole saw bimetal Abraboro HSS-Co 67 x 38 mm AB30067000

Hole saw bimetal Abraboro HSS-Co 67 x 38 mm AB30067000 is a bimetal hole saw designed for cutting circular holes in metal, wood and composite materials. Constructed from high-speed steel with added cobalt alloy, this 67 mm diameter cutter provides a 38 mm cutting depth suitable for applications that require clean through-holes. The tool is compatible with standard arbors and drills and is intended for use where a robust cutting edge and extended life are required in mixed-material environments.

Advantages

The bimetal construction combines a hardened cutting edge with a flexible backing, offering improved wear resistance and reduced risk of tooth breakage compared with simple carbon-steel saws. Cobalt alloy increases heat resistance during prolonged cutting in metal, while the 38 mm cutting depth allows for through-hole and thicker-panel work. Compatibility with common arbors and drill chucks simplifies tool setup and replacement.

Suitable for

• Cutting circular openings in thin and medium-thickness metals (steel, stainless steel, aluminum)
• Drilling holes in wood and laminated or composite panels
• Plumbing and HVAC installations where pipe and duct penetrations are required
• Electrical installations for creating cable and conduit entry points
• General metalworking and maintenance tasks requiring precise round holes

Key specifications

• Material: high-speed steel (HSS) with cobalt alloy
• Diameter: 67 mm
• Cutting depth: 38 mm
• Tooth geometry: bimetal teeth for combined durability and flexibility
• Compatibility: fits standard drill arbors and chucks for through-hole cutting

How to use

Install the Abraboro HSS-Co 67 x 38 mm hole saw on a compatible arbor and secure it in a drill chuck. Mark the center of the desired hole and, where possible, use a pilot drill to maintain accuracy. Begin cutting at low-to-moderate speed, applying steady pressure and allowing the tool to do the work; increase coolant or intermittent cutting when working with thicker or harder metals to control heat. Clear chips regularly and finish the cut carefully to avoid burrs. After use, clean the hole saw and store it in a dry place to prevent corrosion.

Usage recommendations

Use cutting fluid when drilling ferrous metals to extend tool life and reduce heat build-up. For laminated or composite materials, use a backing board to prevent splintering and support the workpiece. Replace or resharpen worn arbors and check tooth condition before each use to ensure accurate, safe cutting.
