Half round files

Shijiazhuang Shuangjian Tools Co., Ltd. supplies half‑round files that combine a flat and a curved filing surface in a single tool. Each file is forged from high‑carbon steel, giving it the wear resistance required for metal, wood and plastic work. The half‑round profile allows the user to address both flat planes and radii without changing tools. The ergonomic polymer handle is moulded to improve grip during extended use.

High‑carbon steel is the standard material for precision filing because it can be hardened to Rockwell C 60 while retaining a fine tooth pattern. Typical hand‑tool manufacturers offer lengths of 250 mm, widths of 30 mm and thicknesses around 5 mm, which match the dimensions most workshops expect. A common tooth count for this class of file is 150 teeth, giving a balanced removal rate and surface finish. Tolerances of ±0.2 mm on length and width are usual in the industry to ensure interchangeability.

These files are widely used in automotive component machining, fine woodworking, and hobbyist plastic modelling where a smooth final surface is required. Both professional toolrooms and small‑scale makers purchase them in bulk, often specifying custom handle shapes or length variations. The supplier does not publish a minimum order quantity, so buyers should confirm the required batch size directly. Shipping can be arranged on FOB or CIF terms, and the buyer should verify incoterms and payment conditions before finalising the contract.
