Diamond-coated cutting and grinding disc Proxxon PR28557 Ø50 mm x 1 mm for LHW and LHW/A

Diamond-coated cutting and grinding disc Proxxon PR28557 Ø50 mm x 1 mm for LHW and LHW/A is a compact, precision accessory designed for use with Proxxon LHW and LHW/A rotary tools. The disc combines a thin 1 mm body with a 50 mm diameter diamond-coated edge to provide controlled, accurate cutting and fine grinding on hard materials. It is intended for tasks that require small-diameter, high-precision abrasion such as model making, jewelry repair, stone and ceramic trimming, and delicate finishing operations.

Advantages

The diamond-coated rim offers durable abrasive performance and consistent cutting action on a range of hard substrates. The 1 mm thickness reduces material removal and allows for narrow kerf cuts and precise shaping. Compatibility with Proxxon LHW and LHW/A ensures stable mounting and accurate rotation at the recommended tool speeds. The compact diameter improves access into tight areas and supports detailed work where larger discs would be impractical.

Suitable for

• Model making and scale modelling components
• Jewellery repair and fine metal shaping
• Stone, tile and ceramic trimming and finishing
• Delicate deburring and precision edge work

Key specifications

• Disc diameter: 50 mm
• Disc thickness: 1 mm
• Coating type: diamond abrasive rim
• Intended tool interface: for use with compatible rotary accessories on Proxxon LHW and LHW/A
• Application: cutting and fine grinding of hard materials

How to use

Fit the disc securely to the Proxxon LHW or LHW/A according to the tool manufacturer’s mounting instructions, ensuring the disc is centered and tightened. Select a moderate rotational speed appropriate for diamond-coated accessories and the material being worked; avoid excessive pressure—let the abrasive do the cutting. Maintain steady, controlled movements for narrow cuts or fine shaping, and pause periodically to check progress and avoid overheating the workpiece or the disc.

Usage recommendations

Wear appropriate eye protection, dust mask and gloves when cutting or grinding hard materials. Use water or a light lubricant only if consistent with the tool manufacturer’s guidance to reduce dust and heat buildup when working with stone or ceramic. Inspect the disc before each use for damage or excessive wear; replace when the diamond rim is worn or compromised.
