Nicholson 03665NN Flat File 10 Inches Bastard Cut Double Cut

Product Description

The NICHOLSON 03665NN is a 10-inch American-pattern flat file designed for stock removal and surface finishing on metal workpieces. It features a double cut pattern with a bastard cut coarseness, which makes it well suited for aggressive material removal on ferrous and non-ferrous metals. The file measures 31/32 inches wide and 11/64 inches thick, giving it a rigid profile that resists flexing during use. A tang end is included for use with a separate handle. Machinists, tool-and-die workers, and general metalworking trades use this type of file for deburring, shaping, and fitting metal parts to close tolerances.

This flat file is used in machining and metalworking applications where flat surfaces, edges, or slots need to be refined or fitted by hand. The bastard cut coarseness is the standard choice for initial material removal before moving to a finer cut. It is appropriate for bench work, fitting operations, and general shop use across manufacturing, maintenance, and repair environments. The rigid, non-flexible body keeps the cutting face flat against the workpiece throughout the stroke.

Key Features

• 10-inch cutting length provides extended reach across larger workpiece surfaces
• Double cut pattern removes material faster than single cut for roughing work
• Bastard cut coarseness balances aggressive stock removal with reasonable surface finish
• 31/32-inch width and 11/64-inch thickness give a flat, rigid cutting face
• Tang end accepts standard file handles sold separately
• Non-flexible body maintains consistent contact angle during hand filing

Compatibility

Designed as an OEM-style replacement or standard shop consumable for use with any standard file handle sized for a 10-inch tang file in metalworking and machining applications.

Installation Notes

A licensed or experienced tradesperson should always fit a proper handle onto the tang before use to prevent hand injury. Secure the workpiece in a vise before filing to maintain control and ensure accurate stock removal. File in one direction along the stroke to extend file life and maintain cutting edge integrity. Inspect the file periodically for clogging and use a file card or brush to clear metal filings from the teeth.
