Hole saw Abraboro HSS-Co bimetal 35 x 38 mm, model AB30035000

Abraboro HSS-Co bimetal hole saw with a 35 mm cutting diameter and 38 mm cutting depth is designed for cutting round holes in a range of materials including steel, non-ferrous metals, and thin-walled construction materials. Constructed from high-speed steel with added cobalt (HSS-Co), this hole saw provides improved heat resistance and greater wear life compared with standard HSS cutters. The tool is compatible with standard arbors and drills that accept bimetal hole saws of this size and is intended for precision hole cutting where durability and consistent performance are required.

Advantages

The bimetal construction combines flexible backing material with hardened cutting teeth to resist chipping and extend service life. Cobalt alloy in the cutting edge increases hardness at elevated temperatures, enabling longer life under heavy cutting or intermittent drilling. The 35 mm diameter and 38 mm depth provide a balance between hole size and cutting capacity for many plumbing, electrical and metalworking tasks. The saw’s tooth geometry and HSS-Co material support steady cutting speed and reduced frequent re-sharpening.

Suitable for

• Cutting circular holes in steel and stainless steel sheets (thin to moderate thickness)
• Creating openings in non-ferrous metals such as aluminum and copper
• Drilling holes for plumbing fittings, electrical boxes and conduit
• Work on thin-walled metal enclosures and HVAC components

Key specifications

• Cutting diameter: 35 mm
• Cutting depth: 38 mm
• Material: bimetal with HSS-Co cutting edge (high-speed steel with cobalt)
• Application: metal, non-ferrous metals, thin construction materials
• Compatibility: fits standard drill arbors for bimetal hole saws of this diameter

How to use

Select a compatible arbor and securely mount the Abraboro HSS-Co bimetal hole saw to the drill. Mark the center of the hole and, where possible, use a pilot drill or pilot bit in the arbor to ensure accurate positioning. Start drilling at low speed to establish the cut, applying steady moderate pressure; increase speed as cutting stabilizes but avoid excessive rpm that can generate heat. Use cutting fluid when working with steel or stainless steel to reduce friction and extend tool life. Withdraw periodically to clear chips and allow cooling during longer cuts.

Usage recommendations

For best results, use a drill with sufficient torque and speed control, keep the cutting edge lubricated when cutting ferrous metals, and replace the hole saw if tooth damage or significant wear is observed. Match the arbor and pilot bit size to the saw and workpiece for safe, accurate cutting.
