! Important !
Diamond stones must be kept constantly wet with water during use.

Sharpening of gouges (sculpting or turning tool).
Maintenance of curved or beveled tools.
Sharpening of hard hydrocarbons (high-speed steels, HSS, carbide, ceramic).
Targeted adjustment of hard-to-reach areas where a flat stone is ineffective.

Instructions for use:
- Keep constantly wet with fresh water during sharpening to improve sliding and prevent the metal from overheating.
- Make regular movements on the conical area to avoid prematurely wearing down one side.
- Rinse the stone after use to remove any metallic particles trapped between the diamond grains.
- Store flat or in a case to preserve the shape.

The diamond stone – Cone 152 mm is a single-crystal industrial diamond sharpening instrument, designed for tools with curved surfaces or non-flat bevels.

- Its conical shape (variable width from 9.5 mm to 19.3 mm) makes it easy to reach curved edges, especially on carving gouges, woodturning tools and other curved blades — this is often difficult to do with classic flat stones.

- The manufacturing process is based on DMT (Diamond Machining Technology), a benchmark in precision diamond abrasives. Single-crystal diamonds are more abrasive and more wear-resistant than ordinary grains, providing fast and durable abrasion even on very hard steels (high-speed steel, HSS, carbide or ceramic).

- As with all diamond stones, the tool must be constantly wet with water during use — this facilitates gliding, limits heating of the cutting edge and maintains abrasion performance.

This diamond stone is particularly useful when working with hand tools or machines with varied profiles where it is necessary to reach difficult angles and surfaces, especially in sculpture, turning or for the maintenance of curved tools.
