## Summary description

## Long description

Proline 89360 is a 300 mm diamond cutting disc for angle grinders with a 25.4 mm bore, supplied as a single unit. It is made using laser-welded construction and is intended for cutting hard materials such as marble, brick, stone and granite; it can also be used for clinker, ceramic and gres tiles, concrete, reinforced concrete and asphalt where appropriate.
Advantages
The laser-welded construction provides a durable bond between the diamond segments and the steel core, ensuring stability during high-speed cutting. The 300 mm diameter allows deeper and longer cuts compared with smaller discs, while the 25.4 mm bore fits angle grinders with the corresponding arbor size. The disc is designed for fast cutting of hard materials commonly encountered in construction and renovation work.
Suitable for
Cutting marble
Cutting brick and masonry
Cutting natural stone and granite
Cutting clinker, ceramic and gres tiles
Cutting concrete and reinforced concrete
Cutting asphalt (where appropriate)
When it may not be suitable
The disc is intended for high-speed abrasive cutting of hard building materials and may not be appropriate for precision finishing or delicate work that requires a fine, non-abrasive edge. It is not specified for use on metals except where incidental contact occurs; avoid using it as a metal-cutting wheel.
Key specifications
Diameter: 300 mm
Bore (arbor) diameter: 25.4 mm
Construction: laser welded
Type: diamond cutting disc for angle grinder
Unit: single disc
How to use
Mount the disc on an angle grinder with a compatible 25.4 mm arbor following the tool manufacturer's instructions and safety guidelines. Use appropriate rotation speed for a 300 mm disc as specified by the grinder and the disc manufacturer, and employ steady, controlled cutting passes without forcing the disc. Wear suitable personal protective equipment including eye, ear and respiratory protection and use water cooling if recommended for the material being cut.
What to consider before purchase
Confirm your angle grinder accepts a 25.4 mm bore and can safely run a 300 mm disc.
Verify the disc type and construction (laser welded) match the materials you plan to cut.
Consider whether a single disc unit meets your project needs or if multiple discs will be required.
Usage recommendations
For efficient and safe cutting of marble, stone, tile and concrete, use the Proline 89360 on compatible angle grinders, keep cuts steady and avoid excessive pressure; follow all safety instructions for diamond discs and power tools.
