Designed for precision work on rings, curved surfaces, and other tight areas, this Grobet USA Swiss Pattern half-round ring file features a slimmer profile than a standard half-round file. Its narrow shape provides greater access and control when filing inside rings and other confined curved surfaces.

The file tapers in both width and thickness toward the point, allowing you to work progressively into smaller areas while maintaining precise control. Both sides are double cut for efficient material removal during shaping, sizing, refining, and general metalworking.

Cut 0 provides a coarse cutting action, making this file well suited for initial shaping and material removal before progressing to finer files or other finishing tools.

Features & Benefits

Frequently Asked Questions

How is a half-round ring file different from a standard half-round file?
A half-round ring file has a narrower profile, making it easier to work inside rings and other tight curved areas where a standard half-round file may be too wide.

What is Cut 0 used for?
Cut 0 provides a relatively coarse cutting action for efficient material removal, initial shaping, and refining before moving to finer finishing tools.

Can this file be used inside rings?
Yes. Its narrow half-round profile is specifically well suited for filing and shaping the inside surfaces of rings.

Are both sides of the file cut?
Yes. Both working surfaces are double cut for efficient material removal.

Does the file taper toward the tip?
Yes. It tapers in both width and thickness toward the point, providing improved access and control in smaller or confined areas.

Is the 6" measurement the total length including the tang?
No. Swiss Pattern file length is measured from where the teeth begin to the end of the file. The tang is not included in the stated file length.
