This 4″ Pillar File is a precision hand tool designed for controlled material removal on firearm components, particularly grip modifications and magwell fitting for the Springfield SA-35 platform. The file solves the problem of accessing tight, narrow channels and corners without marring adjacent surfaces or compromising safety during cuts. Its single-cut #2 (fine) serrations deliver a smooth finish, making it suitable for both bulk removal and final detail work on polymer or metal parts.

FAQ
What does “safe edge” mean on this file?
The narrow faces are smooth and will not cut. This allows you to work into corners or against a reference surface without accidentally removing material from adjacent areas.
Is this file suitable for polymer grip frames?
Yes. The #2 fine cut works well on polymer, nylon, and similar materials for smoothing, deburring, or adjusting fit. Use light strokes to avoid gouging.
Can this file be used for metal trigger work?
While designed primarily for grip/magwell fitting, the #2 single-cut is appropriate for fine metal adjustment on small parts (e.g., trigger shoes, sear edges) where controlled removal is required.
