A coarse file is a hand tool characterized by its large, individually cut teeth designed for aggressive material removal. Unlike finer files used for smoothing, the coarse file excels in shaping, deburring, and rapidly reducing stock on softer materials such as wood, aluminum, plastic, and mild steel. The term “coarse” refers to the cut grade, typically ranging from “Bastard” to “Coarse” or “Rough” in industrial classification. These files are indispensable in metalworking, woodworking, automotive repair, and farriery (horseshoeing). The teeth are often staggered to prevent clogging, a feature known as “overcut” or “double-cut” on many models. Understanding the grit and tooth geometry is critical for selecting the right tool for heavy-duty tasks.

常见问题（10 个常见问题）

What is the difference between a coarse file and a rasp? A coarse file has diagonal teeth cut by a chisel; a rasp has individual, raised teeth for even more aggressive cutting.
Can a coarse file be used on hardened steel? No, coarse files are for materials softer than the file itself (HRC < 60). Use a carbide burr for hardened steel.
How do I clean a clogged coarse file? Use a file card (wire brush) in the direction of the teeth. For resinous wood, soak in kerosene for 10 minutes.
What is the standard length for a coarse file? Common lengths are 6″, 8″, 10″, 12″, and 14″. 12-inch is the most versatile for general work.
Are Chinese coarse files as good as Swiss ones? For general use, Chinese files offer 80% of the performance at 30% of the cost. Swiss files have tighter tolerances for precision work.
What is the MOQ for a custom coarse file order? Typically 5,000 pieces for a custom tooth pattern. Standard patterns may have a 1,000-piece MOQ.
How is the coarseness of a file measured? By the number of teeth per inch (TPI). Coarse files have 20-30 TPI; bastard files have 30-40 TPI.
Can I get a sample before ordering? Yes, most Chinese factories provide 1-3 free samples, but you pay for shipping (DHL/FedEx).
What packaging options are available? Bulk in cartons, individual blister packs, or custom display boxes with branding.
从中国发货需要多长时间？ Sea freight takes 25-40 days. Air freight takes 5-10 days but is 3-4 times more expensive.

Procurement Considerations for Coarse Files

Verify Tooth Consistency

Inspect a sample batch under a magnifying glass. Teeth should be uniform in height and angle. Uneven teeth cause chatter and poor finish.

Check Handle Ergonomics

For hand files, the handle should be securely fitted (no wobble). For machine files, ensure the tang fits standard quick-release chucks.

协商付款条件

Standard is 30% deposit, 70% before shipment (T/T). For large orders, negotiate 30% deposit, 70% against copy of B/L (Bill of Lading).

Understand Tariff Codes

HS Code for coarse files is 8203.10.00 (Files, rasps, and similar tools). Check duty rates in your country (e.g., 3.7% in the US, 0% in EU under certain agreements).
