Nicholson T37423 Swiss-pattern Round Needle File Cut 2

Product Description

The NICHOLSON T37423 is a Swiss-pattern round needle file designed for precise material removal in tight spaces and detailed finishing work. With an overall length of 5.5 inches and a cut length of 2.5 inches, this file delivers controlled stock removal on metal, plastic, and other hard materials. The round file shape allows work in circular openings, curved slots, and contoured surfaces where flat or half-round files cannot reach. It carries a Cut 2 rating, indicating a second-cut tooth pattern suited for moderate material removal with a reasonably smooth finish. A tang end is included for use with a compatible handle, which must be sourced separately. Machinists, toolmakers, and precision fabricators are the primary users of this file type.

This needle file is well suited for deburring, shaping, and finishing operations in tool and die work, precision machining, and general metalworking. Its compact 5.5-inch overall length makes it practical for bench work and detail filing in confined areas. The 0.11-inch width keeps the file profile narrow, which is appropriate for fine-detail work on small parts, ports, and orifices. It is also commonly used in maintenance and repair applications where precision fitting or surface cleanup is required on close-tolerance components.

Key Features

Compatibility

Designed as a needle-style Swiss-pattern file for use in precision metalworking, tool and die, and general fabrication applications requiring a round profile and Cut 2 tooth pattern.

Installation Notes

This file requires a separate handle fitted onto the tang before use to ensure safe operation and proper control. Secure the workpiece in a vise or fixture before filing to prevent movement and reduce the risk of injury. Apply consistent, moderate pressure on the forward stroke and lift or reduce pressure on the return stroke to extend file life. Inspect the file for cracks or damage before each use and do not use a file as a pry bar or hammer.
