Grobet USA Swiss Pattern 7-3/4" Round Needle File – Cut 0

Designed for precise shaping, enlarging, and refining small holes, rounded openings, and curved surfaces, this Grobet USA Swiss Pattern round needle file features a slender, tapered profile for controlled filing in detailed and confined areas.

The circular cross-section provides a consistent working surface for filing inside holes, rounded grooves, curved recesses, and concave contours. Its gradually tapered shape allows access to smaller openings while helping maintain smooth, rounded profiles.

Measuring 7-3/4" (200mm) overall, this longer needle file provides additional reach and a larger working surface while maintaining the control needed for detailed bench work. Cut 0 offers a coarse cutting action for efficient material removal and initial shaping.

Does the file taper toward the point?

Yes. The round profile gradually narrows toward the point, allowing access to smaller holes, tighter openings, and confined areas.

Can this file be used to enlarge small holes?

Yes. Its tapered round shape makes it useful for gradually enlarging and refining small openings while maintaining a rounded profile.

What is the diameter of the file?

The maximum diameter is 5/32" (3.75mm). The file gradually becomes narrower toward the point.

What is the advantage of the longer 200mm size?

The longer profile provides additional reach and a larger working area, making it useful for filing deeper openings and detailed components.

Does this file require a separate handle?

No. It features an integral round knurled handle designed to provide a secure grip and precise control during detailed filing.
