Nicholson 05919N Flat File 8 Inches Smooth Double Cut

Product Description

The NICHOLSON 05919N is an 8-inch American-pattern flat file designed for smooth finishing and material removal on metal, wood, and composite surfaces. It features a double-cut tooth pattern, which uses two intersecting rows of teeth to remove material efficiently while leaving a smoother surface than a bastard or second-cut file. At 25/32 inches wide and 13/64 inches thick, the 05919N has a traditional flat profile with a tang for use with a standard file handle. It is a smooth-cut file, making it best suited for finishing passes rather than aggressive stock removal. Licensed machinists, pipefitters, plumbers, HVAC technicians, and electricians routinely keep flat files like this one in their service kit for deburring, fitting, and surface prep work.

The 05919N is a general-purpose hand file applicable across trades. It is used to deburr pipe ends, clean up threaded fittings, dress valve seats, smooth rough cuts on sheet metal, and fit mechanical components. The flat geometry and smooth-cut double pattern make it a finish-work tool rather than a roughing tool. It is sold individually and ships without a handle, requiring a separately purchased file handle fitted to the tang before use.

Key Features

• Double-cut tooth pattern removes material faster than single-cut while maintaining a smooth surface finish
• Smooth-cut coarseness rated for finishing and final fitting passes
• 8-inch cut length in a flat profile suits a wide range of hand-filing tasks
• 25/32-inch width provides a stable bearing surface on flat workpieces
• 13/64-inch thickness keeps the file rigid without adding unnecessary weight
• Tang end accepts standard file handles sold separately

Compatibility

Designed as a standard American-pattern flat file compatible with any file handle sized for an 8-inch tang. No proprietary system fitment applies.

Installation Notes

A licensed file handle must be seated firmly on the tang before use to prevent hand injury from the exposed tang point. Secure the workpiece in a vise when practical to maintain control and reduce fatigue. Files cut on the forward stroke only; lifting the file on the return stroke extends tooth life. Do not use this file on hardened steel surfaces rated above the file hardness, as this will damage the teeth.
