Grobet USA Swiss Pattern 4" Round Needle File – Cut 0 & 2
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 tight and detailed areas.
The circular cross-section allows the file to work evenly around the inside of holes, curved recesses, and rounded contours. Its tapered shape makes it especially useful for enlarging small openings, smoothing internal curves, and refining details that are difficult to reach with larger files.
Measuring 4" (100mm) overall, these compact needle files provide excellent control for jewelry making, watch and clock repair, model making, and other precision applications. Choose Cut 0 for coarser shaping and faster material removal or Cut 2 for finer, more controlled 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 Cut 0 and Cut 2?
Cut 0 provides a coarser cutting action for faster material removal and initial shaping. Cut 2 provides a finer cutting action for controlled refinement and a smoother finish.
Does the file taper toward the point?
Yes. The round profile gradually narrows toward the point, allowing access to smaller holes and tighter openings.
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.
How long are these files?
Each file measures 4" (100mm) overall, with a 1-3/4" (44mm) cutting portion.
What is the diameter of the file?
The maximum diameter is 3/32" (2.2mm). The file gradually becomes narrower toward the point.
Do these files require a separate handle?
No. They have integral round knurled handles designed to provide a secure grip and precise control during detailed hand filing.
Which cut should I choose for finer finishing?
Cut 2 is the finer option offered on this page and is best suited for controlled refinement and smoother finishing.
Are both cuts included with one purchase?
No. Cut 0 and Cut 2 are individually selectable variants. Choose the cut that best matches the amount of material removal and finish required.
