Hole saw Abraboro HSS-Co bimetal 68 x 38 mm AB30068000

Hole saw Abraboro HSS-Co bimetal 68 x 38 mm is a cutting tool designed for drilling circular holes with a diameter of 68 mm and a cutting depth of 38 mm. Manufactured from high-speed steel with cobalt alloy (HSS-Co) in a bimetal construction, this hole saw is intended for cutting through metals and other hard materials. It is compatible with standard drill chucks and drill presses, providing a robust option for installation and repair tasks that require precise round openings.

Advantages

The bimetal HSS-Co construction combines flexibility and wear resistance to extend tool life when working on stainless steel, carbon steel and other dense materials. Teeth ground for efficient cutting reduce heat build-up and improve chip evacuation, while the 38 mm depth gives sufficient reach for many through-hole and deep-hole applications. The tool’s geometry and material minimize deforming and maintain cutting performance during repeated use.

Suitable for

• Drilling round openings in thin to medium-thickness metal sheets
• Installation of pipes, conduits and cable glands
• Creating access holes for ventilation grilles and flanges
• General mechanical and maintenance workshop work requiring circular cuts

Key specifications

• Cutting diameter: 68 mm
• Cutting depth: 38 mm
• Material: bimetal HSS with cobalt alloy (HSS-Co)
• Tooth design: hardened, ground cutting teeth for improved chip removal
• Intended use: metals and other dense materials
• Compatibility: standard drill chucks and drill presses

How to use

Secure the hole saw in a compatible arbor or chuck according to the drill manufacturer’s instructions. Mark the center point of the hole and, if available, use a pilot bit or guide to prevent wandering. Start drilling at low speed to establish the cut, then increase speed moderately while applying steady, even pressure. Use cutting fluid when working with metals to reduce heat and prolong tool life. After reaching the required depth, withdraw the tool carefully and remove any lodged material from the saw teeth before the next use.

Usage recommendations

Use appropriate safety equipment including eye protection and gloves. Select drill speed and feed rate suitable for the workpiece material; lower speeds are recommended for stainless steel and other hard alloys. Regularly inspect teeth for wear and replace the hole saw when cutting performance declines to maintain clean, accurate holes.
