Nicholson T13196 Square File 10 Inch Bastard Cut Double

Product Description

The NICHOLSON T13196 is a 10-inch square American-pattern file designed for material removal and finishing work on metal, wood, and similar materials. It features a double-cut tooth pattern, which uses two intersecting rows of teeth to remove material faster than single-cut files. The bastard cut coarseness sits between rough and second-cut grades, making it a practical choice for general stock removal and deburring. The file is 3/8 inch wide and includes a tang for use with a standard file handle. It is rigid and does not flex during use. Machinists, maintenance technicians, pipefitters, and general trade professionals commonly keep this type of file in their toolkit.

This square file is suited for enlarging square or rectangular openings, cleaning keyways, filing internal corners, and dressing flat surfaces where a narrower profile is needed. The 10-inch length and bastard cut coarseness make it well-matched to medium-duty hand filing tasks in shop, field, or maintenance environments. It is used in metalworking, pipe fitting, HVAC service, and general mechanical maintenance applications where precise hand filing is required.

Installation Notes

Always fit a proper file handle onto the tang before use to protect the hand and maintain control. Secure the workpiece in a vise when possible to prevent movement during filing. File in one direction with controlled strokes — avoid sawing back and forth, as this dulls teeth prematurely. Keep the file clear of oils and moisture when stored to prevent corrosion of the teeth.
