Angle grinder accessory STHOR 08786 — steel disc Ø 12.5 cm, 1 pc

STHOR 08786 is an angle grinder accessory — a single steel disc with a diameter of 12.5 cm supplied as one piece. The disc is intended for mounting on compatible angle grinders and is manufactured with a steel core and a diamond cutting segment. It is designed for wet work and recommended for cutting porcelain, glass, marble and limestone. The construction and segment dimensions make it suitable for small to medium cutting and surface preparation tasks in workshop or construction environments.

Advantages

The steel core provides structural strength while the diamond cutting segment ensures consistent cutting performance and durability. The segment dimensions (5 mm height, 2.0 mm thickness) balance cutting depth and control, and the disc’s design for wet use reduces dust and heat during operation. Recommended rotation around 12,000 rpm helps achieve efficient cutting speed on the specified materials.

Suitable for

• Cutting porcelain tiles
• Cutting glass elements
• Cutting marble and natural stone
• Small to medium surface preparation and trimming tasks

How to use

Mount the disc on a compatible angle grinder following the tool manufacturer’s instructions and safety guidelines. Use appropriate flange and tightening procedures to secure the disc. For wet cutting, ensure a consistent water supply to the cutting zone to reduce dust and heat. Operate the angle grinder at the recommended rotation speed where possible, apply steady, even pressure, and avoid forcing the disc through the material. Allow the disc to cool periodically during extended use.

Usage recommendations

Always wear appropriate personal protective equipment (eye protection, gloves, hearing protection and a dust mask when not using wet cutting). Verify compatibility of the disc with your angle grinder model and its maximum rpm rating. Use wet cutting for optimal performance on porcelain, glass, marble and limestone and follow safe handling practices to prolong disc life.
