Nicholson T37786 Swiss-pattern Needle File Round Cut 2

Product Description

The NICHOLSON T37786 is a Swiss-pattern needle file in a round shape with a Cut 2 (second-cut) tooth pattern, designed for precision filing work on metals, plastics, and other materials where fine control and accurate stock removal are required. At 6.25 inches overall length with a 3-inch length of cut and a diameter of 0.11 inches, this slim round profile reaches narrow slots, small bores, and contoured surfaces that standard files cannot access. It terminates in a tang for use with a separate handle. Machinists, toolmakers, die makers, and maintenance technicians rely on Swiss-pattern needle files for detail work and deburring in close-tolerance applications.

The T37786 is suited for bench work in machine shops, tool-and-die operations, manufacturing maintenance, and general metalworking. The round cross-section makes it particularly effective for enlarging or refining round holes, filing internal radii, and working curved or cylindrical surfaces. Its needle-class precision level targets fine finishing passes rather than aggressive material removal. No handle is included; a compatible needle-file handle is required before use.

Key Features

• Round file shape accesses bores, slots, and internal curved surfaces
• Cut 2 (second-cut) tooth pattern balances material removal speed with a smooth finish
• Swiss-pattern grading provides consistent, fine tooth geometry for precision work
• Needle-class precision level suited for detail filing and deburring
• Tang end accepts standard needle-file handles for a secure grip
• 0.11-inch diameter fits tight spaces inaccessible to larger files

Compatibility

Designed as an OEM-style Swiss-pattern needle file for general precision metalworking applications; compatible with standard tang-style needle-file handles sold separately.

Installation Notes

A correctly sized tang handle must be seated firmly before use to prevent hand injury from the exposed tang. Secure the workpiece in a vise or fixture before filing to maintain control and accuracy. Apply forward stroke pressure only; lifting on the return stroke extends tooth life. Needle files are not designed for use on hardened tool steel harder than the file itself, as this will damage the teeth.
