Grobet USA Swiss Pattern 6-1/4" Round Needle File – Cut 00-6
Designed for precise shaping, enlarging, and refining small holes, rounded openings, and curved surfaces, these Grobet USA Swiss Pattern round needle files feature a slender, tapered profile for accurate 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. The file gradually tapers toward the point, making it especially useful for working in smaller openings and areas that are difficult to reach with larger files.
Measuring 6-1/4" (160mm) overall, these files offer a comfortable balance of reach and control for jewelry making, watch and clock repair, model making, precision metalworking, and other detailed bench applications.
Available in cuts ranging from 00 through 6, these files provide options for everything from initial shaping and material removal to fine surface refinement.

Frequently Asked Questions
What is a round needle file used for?
A round needle file is designed for shaping, enlarging, and smoothing small holes, circular openings, curved recesses, and rounded contours.
What is the difference between the available cuts?
Lower cut numbers have coarser teeth for faster material removal, while higher cut numbers have finer teeth for greater control and smoother finishing.
Which cut should I choose for initial shaping?
Cut 00 is the coarsest option, making it useful for faster material removal. Cut 0 is also suitable for shaping and enlarging openings.
Which cut is best for general-purpose precision filing?
Cut 2 provides a useful balance between material removal and surface refinement.
Which cut should I choose for finer finishing?
Cut 4 is suited for fine refinement, while Cut 6 provides an even finer cutting action for detailed finishing.
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 these files be used to enlarge small holes?
Yes. Their tapered round shape makes them useful for gradually enlarging and refining small openings while maintaining a rounded profile.
How long are these files?
Each file measures 6-1/4" (160mm) overall.
What is the diameter of the file?
The maximum diameter is 9/64" (3.25mm). The file gradually becomes narrower toward the point.
Do these files require a separate handle?
No. They feature integral round knurled handles designed to provide a secure grip and precise control during detailed filing.
Are all cuts included with one purchase?
No. Each cut is an individually selectable option. Choose the cut that best matches the amount of material removal and finish required.
