Shimomura Alec (職人堅気) Iron U Light Metal File 16mm - Grit #400 & Grit #1000 (K241)

Special model with CNC (computer numerical control) milling and craftsmanship!

The unique valley U-groove structure eliminates clogging.

Use it and feel it! Adopts "carburizing and nitriding" quenching method to obtain surface hardening layer!

Can cut: brass, copper and other light metals, polypate, solder, wood chips, acrylics, etc.

Single grit (#1000 or equivalent) can be used to file fine etched parts with minimal drag.

The double grain (equivalent to #400) has good cutting power, and the single grain finishes cleanly, resulting in much better work efficiency.
