Diamond Cutting Disc Keltin for Concrete 230×22.2×10 mm Black

Keltin Diamond Cutting Disc for Concrete 230×22.2×10 mm Black is a professional abrasive wheel designed for cutting concrete, masonry and reinforced concrete with angle grinders and similar powered cutting tools. The disc features a 230 mm diameter with a 22.2 mm mounting bore and a 10 mm segment height, delivering stable cutting performance for construction and renovation tasks. The black finished blade is intended for heavy-duty use where durability and consistent cutting speed are required.

Advantages

The diamond segments provide aggressive material removal and long life compared with conventional abrasive discs, while the robust steel core ensures reduced vibration and improved stability during operation. The 10 mm segment height extends service life under frequent cutting conditions. The standard 22.2 mm bore fits most common angle grinders and allows secure mounting for safe cutting of concrete and block materials.

Suitable for

• Cutting concrete slabs and blocks
• Trimming reinforced concrete edges and beams
• Making openings for plumbing and electrical installations
• Renovation and demolition tasks requiring straight cuts

Key specifications

• Diameter: 230 mm
• Mounting bore diameter: 22.2 mm
• Diamond segment height: 10 mm
• Intended material: concrete, masonry, reinforced concrete
• Finish: black coated steel core with diamond segments
• Tool compatibility: handheld angle grinders and similar cutting machines

How to use

Mount the disc on a compatible angle grinder with a 22.2 mm arbor and ensure the flange and locking nut are tightened according to the tool manufacturer’s instructions. Verify that the machine is disconnected from power while fitting the disc. When cutting, secure the workpiece and use steady, controlled passes without forcing the disc; allow the diamond segments to cut at their designed feed rate. Maintain correct cutting line and a stable posture; use a dust extraction system or wet cutting method where appropriate to reduce dust. Inspect the disc regularly for wear or damage and replace when segment height is critically reduced or if cracks appear.

Usage recommendations

Use appropriate personal protective equipment: safety goggles, hearing protection, dust mask or respirator, and cut-resistant gloves. Match disc speed rating to the angle grinder’s no-load RPM and avoid side loading or lateral pressure that exceeds recommended use. For prolonged life, make intermittent cuts and allow cooling periods when performing long continuous cuts.
