Diamond Cutting Disc GRAPHITE 180 x 22.2 mm model 57H644 for dry and wet cutting

The GRAPHITE Diamond Cutting Disc 180 x 22.2 mm (model 57H644) is a segmented diamond blade designed for precise cutting of hard building materials. With a 180 mm diameter and a 22.2 mm bore, the disc fits most standard angle grinders and cutting machines. It is built for both dry and wet cutting applications and intended for use on concrete, natural stone, ceramic materials and similar surfaces encountered in construction and renovation work.

Advantages

The blade combines a hardened steel body with a continuous segmented diamond edge to provide consistent cutting performance and extended service life. Its design enables efficient material removal and reduced load on the machine during cutting. The disc is suitable for use in both dry and wet conditions, allowing flexible application on job sites where water supply may or may not be available. Balanced construction helps to minimize vibration for smoother, more controlled cuts.

Suitable for

• Cutting concrete and reinforced concrete
• Cutting natural stone and masonry
• Cutting ceramic tiles and porcelain
• Precision trimming during renovation and installation work

Key specifications

• Diameter: 180 mm
• Bore (arbor) diameter: 22.2 mm
• Cutting method: suitable for dry and wet cutting
• Edge type: segmented diamond rim for efficient cutting and cooling
• Typical use materials: concrete, stone, ceramic

How to use

Mount the cutting disc on a compatible angle grinder or cutting machine ensuring the arbor size matches 22.2 mm. Secure the disc according to the tool manufacturer’s instructions and check for runout before use. When cutting, use steady feed pressure and allow the diamond segments to do the work; avoid excessive force which can reduce blade life. For dry cutting, follow the tool’s duty cycle and cooling intervals; for wet cutting, supply a consistent water flow to the cutting zone to reduce dust and improve cutting speed. Always observe safety precautions including eye, ear and respiratory protection and secure the workpiece before starting.

Usage recommendations

Use the disc on the materials specified and select appropriate cutting speed and pressure for the thickness and hardness of the workpiece. For best blade life and cut quality, prefer wet cutting when possible; for dry cutting, work in short passes and allow the disc to cool. Inspect the disc before each use for cracks or damage and replace if any defects are found.
