Nicholson T37451 Swiss-pattern Half Round File Cut 2

Product Description

The NICHOLSON T37451 is a Swiss-pattern needle file in a half round profile, designed for precision material removal and fine finishing work on metal, plastic, and other hard materials. Cut 2 gives this file a medium-fine tooth pitch suited to deburring, fitting, and light shaping tasks where control matters more than aggressive stock removal. At 5.5 inches overall length with a 2.5-inch length of cut, it is built for close-tolerance hand filing in tight spaces. The tang end accepts a separately purchased handle. This file is a standard tool-of-the-trade for machinists, toolmakers, HVAC fabricators, plumbers, and electricians who need consistent, repeatable results in finish filing.

Swiss-pattern needle files at Cut 2 are used in precision fitting applications across residential and commercial trades. Common scenarios include fitting valve seats, deburring copper tubing ends, cleaning electrical contact surfaces, and dressing burrs from drilled or tapped holes. The half round profile addresses both flat and curved surfaces in a single tool, making it practical for work on pipe fittings, conduit knockouts, sheet metal edges, and machined components. The narrow 0.2-inch width and 0.07-inch thickness allow access to grooves and slots where wider files cannot reach.

Key Features

• Cut 2 Swiss-pattern tooth pitch delivers medium-fine material removal suitable for deburring and finish fitting
• Needle file classification provides precise control in tight or intricate workspaces
• 2.5-inch length of cut gives adequate working surface for most hand-filing tasks
• Slim cross-section at 0.2 inches wide and 0.07 inches thick fits narrow slots and grooves

Compatibility

Designed as an OEM-style precision hand file suitable for general metalworking, trade fabrication, and maintenance applications where a Swiss-pattern half round needle file at Cut 2 is specified.

Installation Notes

Install a correctly sized handle onto the tang before use to prevent hand injury from the exposed tang point. Always stroke the file in one direction across the workpiece to preserve tooth geometry and avoid premature wear. Secure the workpiece in a vise or clamp before filing to maintain control and consistent cut angle. A file card or brush should be used regularly to clear filings from the teeth.
