Diamond-coated Cutting Disc with Shank Proxxon UNI Cut 45 (PR28849)

Proxxon UNI Cut 45 is a diamond-coated cutting disc with an integrated shank, created for precision cutting with rotary tools and mini-drills. The compact, shank-mounted design allows direct attachment to compatible collets or chucks, providing a slim profile for access to narrow areas. The diamond-coated edge gives abrasion-resistant cutting performance suited to hard, brittle materials while maintaining a consistent cut line for detailed tasks.

Advantages

The diamond coating ensures durable abrasion resistance and longer life on hard materials compared with non-coated blades. The integrated shank simplifies mounting and reduces accessory swaps, while the small disc diameter improves control and visibility when performing fine cuts. Designed for use with handheld rotary tools, the accessory balances precision and robustness for tasks that require accuracy in confined spaces.

Suitable for

• Cutting ceramic tiles, porcelain and pottery
• Scoring and trimming glass and mirror edges
• Shaping and cutting natural stone and slate
• Detail work on hardened composites and similar brittle materials

When it may not be suitable

This diamond-coated cutting disc is intended for thin, brittle and hard materials; it is not optimized for heavy stock removal or for cutting large, thick metal sections. For high-volume industrial cutting or large-scale masonry work, a larger wheel or dedicated saw with appropriate power handling and cooling is recommended. Users should also avoid using the disc on soft metals or wood where a different tooth geometry or abrasive is more appropriate.

Key specifications

• Accessory type: diamond-coated cutting disc with integrated shank
• Mounting: shank for direct insertion into rotary tool collets or mini-drill chucks
• Intended materials: ceramics, glass, stone, hardened composites
• Application: precision cutting, scoring, trimming and detailing

How to use

Select a compatible rotary tool or mini-drill with a collet or chuck that accepts the shank diameter. Secure the shank firmly, set a suitable rotational speed recommended for diamond cutting on brittle materials (moderate to high speed while avoiding excessive load), and make light, controlled passes. Use steady pressure and allow the diamond coating to abrade the material rather than forcing the disc. For glass and ceramics, consider using intermittent cutting and keeping the workpiece supported to reduce chipping.

What to consider before purchase

• Confirm shank diameter compatibility with your rotary tool or mini-drill collet
• Assess whether the disc diameter and thickness suit the cuts and access required
• Verify that the target materials are hard, brittle or abrasive (ceramics, glass, stone)
• Consider required rotational speed range and tool power for safe, effective cutting

Usage recommendations

Wear appropriate eye and respiratory protection, clamp workpieces securely, and use light, steady pressure. To extend disc life, avoid overheating by using intermittent operation and allow the disc to cool between extended cuts. Use water or a coolant only if the tool and disc specifications allow wet use; otherwise, operate dry and monitor for excessive heat or glazing of the diamond surface.
