Circular saw blade GRAPHITE 57H645 — 1 pc

Circular saw blade GRAPHITE 57H645 is a single-piece solid diamond disc with a diameter of 250 mm and a 25.4 mm bore, intended for use with compatible circular saws and tile cutters. The blade features a hot-pressed diamond segment bonded to a full steel body, providing a durable cutting edge designed specifically for hard and brittle materials such as glazed tiles, porcelain stoneware, terracotta, granite and marble. The product is supplied as one unit and is intended for workshop and construction tasks where a replaceable high-strength cutting blade is required.

Advantages

The hot-pressed diamond segment ensures high wear resistance and consistent cutting performance over extended use. A solid disc construction provides stability and reduced vibration during cutting, improving edge quality on ceramic and natural stone. The 25.4 mm bore diameter matches common arbor standards, enabling straightforward fitting to many circular saws and tile cutting machines. The blade is optimized for dry or wet cutting applications depending on the machine and cutting method used.

Suitable for

• Cutting glazed ceramic tiles and porcelain stoneware
• Shaping and trimming terracotta and fired clay elements
• Cutting natural stone such as granite and marble
• Workshop and on-site tile cutting for renovation and construction projects

How to use

Fit the GRAPHITE 57H645 blade to a compatible circular saw or tile cutter with a 25.4 mm arbor, ensuring the machine is switched off and disconnected from power before installation. Tighten the blade according to the tool manufacturer’s instructions and confirm the blade rotation direction matches the saw’s rotation arrow. When cutting, secure the workpiece, set an appropriate cutting speed and feed rate, and use steady, even pressure. For ceramic and natural stone, consider using water cooling when the tool supports wet cutting to reduce dust and extend blade life. Observe all safety measures, including eye, ear and respiratory protection.

Usage recommendations

Use the blade for recommended materials and avoid excessive side pressure or lateral twisting. For best results on porcelain and glazed tiles, perform initial scoring or shallow passes before completing the full-depth cut. Inspect the blade before each use for damage or abnormal wear and replace if the diamond segment is worn or the disc shows cracks. Follow the saw manufacturer’s RPM limits and safety guidelines.
