Key benefits at a glance

• Ultra-thin profile at 1mm thickness for precise, chip-free cuts that preserve surface integrity.
• Porous design helps manage heat buildup, supporting steady performance and longer disc life.
• Diamond high manganese steel with upgraded brazing technology for faster cutting action and reliable durability.
• Flexible cutting suitable for dry or wet operation, adapting to your workflow and material hardness.
• Multipurpose use for cutting, grinding, and chamfering across rock slabs, ceramics, marble, tiles, jade, glass and more.

Real-world scenarios

In a busy workshop, the disc can be used to bevel edges on a porcelain tile batch, trim irregular rock slabs, or clean up the contact surfaces on glass installations. The fine edge produced by the 1mm thickness helps minimize surface damage while maintaining a clean, professional look on finished pieces.

Operators often appreciate the balance between aggressive material removal and surface preservation. The porous design helps prevent overheating during extended cuts, letting you work more efficiently without frequent tool changes.
