High-Precision Diamond and Cubic Boron Nitride (CBN) Files
Diamond and CBN files are specifically designed for precision manual finishing, deburring, and profile shaping of difficult-to-machine materials. We offer a wide variety of specifications to meet diverse finishing needs, including thin flat files, precision needle file sets (in 5-piece or 10-piece sets), and heavy-duty files suitable for industrial maintenance.
These tools are manufactured using an advanced electroplated process that securely bonds high-quality superabrasives to a durable, high-rigidity steel core. This single-layer structure with high grain protrusion ensures highly aggressive cutting forces and long-lasting wear resistance. Even when machining the hardest workpieces, they maintain sharp cutting edges and fine geometric profiles for significantly longer periods than traditional steel files.
Material-Specific Filing Solutions:
• Diamond Files: Dedicated to non-ferrous and hard-brittle materials. The ideal choice for polishing Tungsten Carbide cutting tools, precision ceramics, glass, quartz, and sapphire edges.
• CBN (Cubic Boron Nitride) Files: Dedicated to ferrous metals. Excels in fine-finishing die steel, High-Speed Steel (HSS), alloy steel, stainless steel, and cast iron, delivering an excellent cutting feel and extended tool life.

Core Industrial Applications
• Mold & Tooling Industry
Applications: Fine finishing of mold cavity details, sharpening tool cutting edges, and deburring Tungsten Carbide and die steel punches.
Advantage: Highly suitable for processing narrow corners and complex mold details. The extreme cutting efficiency of superabrasives allows for precise control over material removal while durably maintaining the file's shape.
• Ceramics, Glass & Advanced Materials
Applications: Edge smoothing and chamfering of ceramics, sapphire, quartz, and optical glass.
Advantage: Enables highly delicate cutting force control, effectively minimizing edge chipping on brittle materials. It is the best countermeasure when severe mechanical grinding is not viable.
• Semiconductor & Electronics
Applications: Edge conditioning or profile shaping of silicon wafers, aluminum nitride substrates, and fragile ceramic components.
Advantage: In situations where mechanical grinding is impractical or spatially restricted, it provides precise manual correction and micro-adjustments for extremely hard semiconductor substrates such as Silicon Carbide (SiC).
• Medical & Precision Instruments
Applications: Fine finishing of stainless steel, titanium alloy, and ceramic components used in surgical instruments and dental tools.
Advantage: Delivers a high-quality, burr-free, and smooth surface, which is critical for the safety and functionality of medical devices.
• Beauty & Personal Care Industry
Applications: Edge refinement of high-end hairdressing scissors, manufacturing of nail care filing tools, and deburring/polishing of precision cosmetic tweezers (stainless steel or special alloys).
Advantage: Enables micro-adjustments on extremely delicate blade edges or instrument contours. It provides a smooth, scratch-free, fine surface to ensure the ultimate sharpness of high-end beauty tools and absolute safety upon skin contact.
• Maintenance, Repair, and Operations (MRO)
Applications: On-site tool maintenance on the production line, deburring machine parts, or repairing small areas of mold wear.
Advantage: Highly portable and easy to use. Whether dealing with High-Speed Steel (HSS) drills, Tungsten Carbide end mills, or hardened coated parts, there are corresponding CBN or Diamond files available to deliver outstanding repair results.
