Product Description:
Durable Medium‑Tooth Round Bearing Steel File with Comfort Dual‑Color Handle for Inner‑Hole & Curved‑Surface Polishing
Our dual‑color plastic‑handle round files are professional industrial‑grade hand‑grinding tools, precision‑manufactured from premium high‑carbon bearing steel with strict overall quenching heat‑treatment. Featuring ergonomic dual‑color non‑slip plastic handles and standardized medium‑tooth grinding surfaces, these files realize neat, smooth burr‑free polishing and trimming for inner holes, circular grooves and curved metal surfaces, widely applied in metal processing, mold‑hole finishing, hardware‑part maintenance and DIY handcrafting scenarios. Available in 4 mainstream size specifications, they adapt to diversified small‑detail to large‑area inner‑hole grinding demands, favored by professional metal‑processing workers and B2B industrial‑tool wholesale buyers worldwide.
The file body adopts high‑quality bearing steel with integral quenching treatment, greatly improving overall hardness, wear resistance and grinding efficiency for long‑term heavy‑duty use. Precision‑machined medium‑tooth structure with ideal tooth height and pitch removes workpiece burrs efficiently while keeping polished surfaces neat and flat. The round cross‑section design perfectly matches inner‑hole, circular‑groove and irregular curved‑surface grinding tasks that flat‑type files cannot handle, expanding application scope. The dual‑color TPR plastic handle integrates anti‑slip texture and ergonomic curved shape, lowering hand fatigue during long‑time continuous grinding work. Four‑size options cover fine small‑part hole polishing to large‑area circular‑surface rough‑finishing needs. Inner‑box packaging protects the sharp‑tooth file body from damage during storage and logistics transportation, suitable for bulk‑order wholesale and retail sales.
