Grobet USA Swiss Pattern 4" Half-Round Needle File – Cut 0 & 2
Designed for precise shaping, filing, and refinement of both flat and curved surfaces, these Grobet USA Swiss Pattern half-round needle files combine a flat face with a rounded face for versatile precision work.
The half-round profile tapers in both width and thickness toward the point, allowing access to small openings, inside curves, concave surfaces, and confined areas. Both the flat and rounded faces are double cut for efficient, controlled material removal.
Choose Cut 0 for coarser shaping and faster material removal or Cut 2 for more controlled filing and smoother refinement. The compact 4" size provides excellent control when working on small components and detailed areas.

Frequently Asked Questions
What is a half-round needle file used for?
The combination of a flat face and rounded face makes it useful for both flat surfaces and inside curves, concave areas, rounded openings, and other detailed shapes.
What is the difference between Cut 0 and Cut 2?
Cut 0 removes material more aggressively and is better for initial shaping. Cut 2 provides a finer cutting action for more controlled refinement and a smoother finish.
Are both sides of the file usable?
Yes. Both the flat and rounded working surfaces are double cut.
Does the file taper?
Yes. The profile tapers in both width and thickness toward the point, making it easier to reach smaller and more confined areas.
How long are these files?
Each file measures 4" (100mm) overall.
Do these files require a separate handle?
No. They have integral round knurled handles for a secure grip and precise control.
Are both cuts included with one purchase?
No. Cut 0 and Cut 2 are individual selectable variants. Choose the cut that best matches the amount of material removal and finish required.
