Hole Saw Abraboro BiM 98 mm — Abraboro AB30098000, Bi-metal construction, 8% cobalt

Abraboro BiM 98 mm hole saw is a bi-metal cutting tool engineered for drilling clean circular openings with a nominal diameter of 98 mm. The cutting edge contains 8% cobalt in a BiM (bimetal) construction that improves wear resistance and edge life when cutting through metals and mixed constructions. The tool is intended for professional use by installers and tradespeople who require a durable hole saw for making openings in pipes, panels and structural components.

Advantages

The BiM 98 mm hole saw combines a flexible steel backing with a high-speed steel cutting edge alloyed with 8% cobalt, providing greater toughness and longer life compared with standard HSS edges. This construction reduces premature tooth wear when cutting stainless steel, non-ferrous metals and sandwich materials. The design delivers consistent hole diameter, efficient chip evacuation and stable cutting performance under typical installation conditions.

Suitable for

• Drilling circular openings in metal panels and sheet steel
• Cutting holes for pipe penetrations and cable glands
• Creating openings in composite or sandwich panels
• On-site installations and maintenance work by tradespeople

Key specifications

• Nominal hole diameter: 98 mm
• Cutting material: bi-metal (BiM) edge with 8% cobalt
• Construction: bimetal with flexible steel body and HSS-based teeth
• Intended materials: metals, mixed construction materials, composites
• Typical application: through-holes in panels, pipes and structural components

How to use

Select an appropriate arbor and pilot drill for the 98 mm hole saw, secure the arbor in a compatible drill or drill press, and mount the hole saw firmly. Mark the centre point of the hole, position the pilot bit, and start drilling at low speed to establish guidance. Apply steady pressure and moderate speed, allowing the teeth to cut and clear chips. Use cutting lubricant when drilling ferrous metals to reduce heat and extend tool life. After completing the cut, retract the hole saw and remove the slug carefully.

Usage recommendations

Use the hole saw with the correct arbor and pilot bit size, maintain moderate drilling speed, and apply suitable cutting fluid for metal work. Inspect the teeth for wear and replace the tool when cutting efficiency declines to ensure safe and accurate holes.
