Grobet USA Swiss Pattern 5-1/2" Round Needle File – Cut 0, 2 & 4
Designed for precise shaping and refinement of small holes, rounded openings, and curved surfaces, these Grobet USA Swiss Pattern round needle files feature a slender, tapered profile for controlled filing in detailed and confined areas.
The circular cross-section allows the file to work along the inside of holes, rounded grooves, and curved recesses. Its gradually tapered shape makes it particularly useful for enlarging small openings, smoothing internal curves, and refining rounded details that are difficult to reach with larger files.
Measuring 5-1/2" (140mm) overall, these files offer an excellent balance of reach and control for jewelry making, watch and clock repair, model making, precision metalworking, and other detailed bench applications.
Choose Cut 0, Cut 2, or Cut 4 to match the amount of material removal and surface finish required.

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 Cut 0, Cut 2, and Cut 4?
Cut 0 provides a coarser cutting action for faster material removal and initial shaping. Cut 2 offers a medium cutting action for general refinement, while Cut 4 provides finer cutting for detailed finishing.
Which cut should I choose for initial shaping?
Cut 0 is the best choice when faster material removal or initial shaping is needed.
Which cut is best for general-purpose precision filing?
Cut 2 provides a useful balance between material removal and surface refinement, making it a versatile choice for general precision work.
Which cut should I choose for finer finishing?
Cut 4 is the finest option offered on this page and is best suited for controlled refinement and smoother 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 5-1/2" (140mm) overall, with a 2-1/2" (64mm) cutting portion.
What is the diameter of the file?
The maximum diameter is 1/8" (3.0mm). 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 three cuts included with one purchase?
No. Cut 0, Cut 2, and Cut 4 are individually selectable variants. Choose the cut that best matches the amount of material removal and finish required.
