Nicholson 07688NN 12 in Lathe File Single Cut Bastard

Product Description

The NICHOLSON 07688NN is a 12-inch American-pattern lathe file designed for material removal and finishing on metal and wood workpieces. It features a single-cut bastard tooth pattern, which produces a smoother surface finish than a double-cut file while still removing material efficiently. The tang configuration allows it to fit a standard file handle, giving the user a secure grip during operation. This file is a non-flexible, rigid tool suited for bench work, lathe operations, and general-purpose hand filing tasks. It is a standard tool in the kit of machinists, pipefitters, and general tradespeople who need controlled material removal on ferrous and non-ferrous metals as well as wood.

The 07688NN is used in shop environments and field settings where material shaping, deburring, or surface preparation is required. Its 12-inch cutting length makes it appropriate for medium to large workpieces. It is commonly used in lathe operations to refine turned parts, smooth weld seams, dress mating surfaces, and remove burrs from cut pipe or bar stock. The single-cut bastard configuration is a common first-pass or finish-pass choice for machinists and metalworkers working on steel, cast iron, aluminum, and hardwood.

Key Features

• 12-inch overall length provides reach and leverage for lathe and bench filing tasks
• Single-cut tooth pattern produces cleaner, smoother surface finishes than double-cut
• Bastard coarseness grade balances material removal rate with surface quality
• Tang design accepts standard file handles for secure, controlled grip
• Rigid construction — non-flexible — for consistent pressure and flat filing
• Rated for use on metal and wood applications

Compatibility

Designed as an OEM-style replacement or direct-use American-pattern lathe file compatible with standard tang-style file handles used in machining, pipefitting, and general trade applications.

Installation Notes

Always seat the tang fully into a properly sized handle before use to prevent hand injury from an exposed tang. File in controlled strokes with appropriate pressure for the material being worked. Eye protection should be worn during filing operations. Inspect the file for cracks or missing teeth before each use and replace if damaged.
