Hole saw Abraboro HSS-CO bimetal 86 x 38 mm AB30086000

The Abraboro HSS-CO bimetal hole saw 86 x 38 mm is a circular cutting tool designed to create precise round holes in metal and other common construction materials. Manufactured from high-speed steel with cobalt alloy (HSS-CO), this hole saw combines hardness and toughness to maintain cutting performance and wear resistance in demanding applications. Its 86 mm diameter and 38 mm cutting depth are suited for tasks that require consistent, clean hole edges and reliable tool life.

Advantages

Construction in HSS-CO bimetal provides improved heat resistance and longer cutting life compared with standard high-speed steel. The saw's tooth geometry and bimetal bonding deliver durable performance when cutting ferrous and non-ferrous metals, while the 38 mm cutting depth allows through or partial-depth holes in sheet metal, thin plate and composite materials. The tool is compatible with standard hole saw arbors and quick-change systems, enabling efficient setup and stable operation.

Suitable for

• Cutting round openings in metal sheets and plates
• Installing plumbing and HVAC fixtures where circular penetrations are required
• Electrical installations for mounting boxes and conduit entries
• General metalworking and fabrication tasks requiring precise round holes

Key specifications

• Material: HSS-CO bimetal (high-speed steel with cobalt)
• Diameter: 86 mm
• Cutting depth: 38 mm
• Tooth type: bimetal saw teeth for metal cutting
• Compatible with standard hole saw arbors and mandrels

How to use

Secure the appropriate arbor into a drill or drill press, and mount the hole saw firmly on the arbor according to the arbor manufacturer's instructions. Mark the centre of the required hole and use a pilot drill if available to guide the saw. Start drilling at low speed to establish the cut and increase speed as appropriate for the material and machine. Apply steady, moderate feed pressure and allow the tool to do the cutting; withdraw periodically to clear chips and reduce heat buildup. Use cutting fluid when working with ferrous metals to improve chip evacuation and extend tool life.

Usage recommendations

For best results, select an arbor and pilot bit sized for the 86 mm hole saw, maintain recommended spindle speeds for the specific metal being cut, and use appropriate coolant or lubricant. Inspect teeth before use and replace the saw if excessive wear or damage is present to ensure clean, safe cuts.
