10PCS-5.5-Inch Diamond Special-Shaped File Set, Curved Files Tool,Needle Files for Metal,Alloy Diamond Tool Grinder for Stone Carving, Metal Polishing & Model Making

For crafters, metalworkers, or model builders, working with hard materials like stone or metal often means struggling with tools that can’t reach small gaps or lose sharpness quickly. This 10-pack of 5.5-inch diamond special-shaped files solves those frustrations, with diamond-coated tips that grind through tough materials and multiple shapes to handle every detail of your project.Each file is 5.5 inches long—compact enough to maneuver in tight spaces, but long enough to give you control over strokes. The diamond coating is the key: it stays sharp longer than traditional metal files, so you can shape stone carvings or metal parts without stopping to sharpen. The alloy handle fits comfortably in your hand, even during long crafting sessions, and the non-slip surface ensures you won’t lose grip when applying pressure.As needle files for metal, they’re perfect for jewelry makers refining silver or copper pieces—removing burrs from wire edges or shaping small metal components for necklaces or earrings. For stone carvers, they act as reliable stone carving tools, letting you smooth gemstone surfaces or carve tiny details into sculptures without chipping the material. Model builders will love the Miniature and Model Files—the triangular tips fit into small grooves of plastic or metal kits, and the round tips smooth curved contours of miniature cars or figurines.The 10-pack includes all the shapes you need: flat for straight edges, round for holes, half-round for curves, triangular for angles, and square for corners—no need to buy separate files for different tasks. Whether you’re working on a small jewelry project, a stone sculpture, or a detailed model kit, these files make precise shaping easy. Just remember to use light pressure on delicate materials and clean the tips after use—with proper care, they’ll be a go-to tool in your craft kit for years.

• This set includes 10 diamond-coated special-shaped files (5.5 inches long), designed for grinding, shaping, and polishing hard materials like stone, metal, and model parts—equipped with alloy bases for stable handling during detailed work. As needle file set, it offers multiple tip shapes to tackle different grooves, edges, and small surfaces, making it versatile for precise crafting tasks.
• Each file measures 5.5 inches in total length and features a diamond-coated working area that adheres to hard materials; the alloy handle provides a non-slip grip for steady control. As small metal file, the diamond coating grinds through metal surfaces without dulling quickly, suitable for shaping thin metal sheets, removing burrs, or refining metal model components.
• These files have special-shaped tips that reach narrow gaps, curved edges, or tiny recesses—areas regular flat files can’t access—ensuring detailed shaping for intricate projects. As Curved Files Tool, the half-round and round tips smooth curved surfaces evenly, avoiding uneven grinding that ruins project details.
• Ideal for stone carvers (shaping gemstones or sculptures), metalworkers (polishing small metal parts), or model builders (refining miniature kits)—works in workshops, home craft rooms, or jewelry-making studios. As stone carving tools, a handy tip: use light pressure when grinding stone to prevent the diamond coating from chipping; for metal, apply steady, slow strokes to avoid overheating the file or material.
• As Miniature and Model Files, note that these are designed for small-scale projects—do not use them on thick metal blocks or large stone pieces, as this may damage the diamond coating or bend the file. Also, clean the file with a soft brush after use to remove debris; hard particles left on the coating can reduce grinding efficiency next time.
