Circle Cutters, Sintered (Metal Bond)
Circle Cutters are precision-engineered diamond tools designed for gemstone artists who demand both accuracy and creative freedom. Built with a cylindrical body and a cutting rim or inner edge, these tools allow the production of exact circular or concave shapes that are difficult, if not impossible, to achieve with traditional methods. Each cutter is manufactured with sintered (metal bond) construction, incorporating premium-grade diamond concentrations for long-lasting performance and consistency. This design ensures durability even under the rigorous demands of competition-level faceting. Optimized for use on fantasy faceting machines such as the Ultra Tec, Circle Cutters give both professionals and advanced enthusiasts the ability to introduce entirely new dimensions of brilliance and design into their work.
Diamond Cylindrical Tools for Faceting
SMART CUT® Diamond Cylindrical Tools for the UltraTec fantasy machine are sintered metal bond tools fully impregnated with diamond from the outside diameter to the inside of the cylinder head. The working section contains hundreds of diamond layers throughout the full diamond depth, which provides long service life, stable cutting rates, and consistent performance as new diamond is exposed during use.
These tools are produced in a range of diameters typically used for fantasy cutting. Common sizes include 6 mm, 8 mm, 13 mm, 15 mm, 17 mm, and 23 mm. Other Diameters also available. This range allows you to select the proper diameter based on the depth of cut, groove width, and required level of design detail.
Diamond Wire Loops
SMART CUT® Diamond Wire Loops are closed-loop precision tools mounted on pulleys and designed for high-accuracy cutting of wafers, optics, and crystals. Unlike spool-based systems, loop wires maintain stable and consistent tension across the entire loop, ensuring repeatable performance, minimal vibration, and extremely clean cuts. This makes them the preferred choice in laboratories, research facilities, and advanced production environments where tolerances are tight and surface quality is critical. They are manufactured with wire diameters ranging from 80 to 350 µm, using core materials such as high-tensile steel, tungsten, molybdenum, and NiTi alloys.
Diamond Wire Spools (Bobbin-Based)
SMART CUT® Diamond Wire Spools, also known as bobbin-based diamond wire, are specifically designed for extended, continuous cutting operations. They are ideal for processing large ingots, slabs, and blocks where long cutting paths are required. Unlike looped wire systems, spool-based wire is wound onto reels and fed continuously through the workpiece, meaning that fresh abrasive sections are always in contact with the material. This feature ensures steady cutting performance and consistent quality across very long cuts, making the method indispensable for heavy-duty production environments.
