Six-piece needle file set made of carbon steel with high hardness. The fine-grained texture is deeply quenched and coated for long-lasting cutting performance. Key features and benefits - Durable material: carbon steel provides high hardness and long cutting life, with a deeply quenched and coated finish for extended use. - Complete set for versatile filing: includes six shapes to cover a range of tasks - flat steel file - flat protective steel file - square steel file - triangular steel file - round steel file - semi-circular steel file - Comfortable and practical handling: ergonomic design with a non-slip rubber handle that stays secure even when wet. A hanging hole at the bottom of the handle enables easy storage. - Precise and efficient filing: a clear surface grain on the precision metal file and clearly defined gear teeth on the metal wood file promote efficient cutting. Note: do not use a steel needle file as a crowbar, as it can break easily. What this set is for - General shaping and deburring in metalworking and woodworking projects - Finishing and detailing in tight spaces and curves where larger files cannot reach - Fine work in hobby projects, model making, or jewelry where precision is important Specific use scenarios - Woodworking: smoothing edges, shaping edges and slots, and refining curved profiles on small wooden parts. - Metalworking: deburring and fine shaping of metal components, enlarging or finishing narrow openings, and detail work in tight areas. - Hobby and model work: precise detailing and finishing in confined spaces where multiple shapes are needed to achieve a smooth surface. Care and handling notes - Do not use the files as pry bars or crowbars, as this can cause breakage. - Wipe clean after use and store in a dry place to preserve coating and cutting performance.
