The 300 Grit Diamond Fret File, an essential tool for achieving precise fret dressing and improved clearance over the guitar body, especially on higher frets. This offset file has been meticulously designed to provide maximum comfort during use.
With its dual-edge configuration, this file caters to both narrow/medium and medium/wide fretwire. One side of the file is perfectly suited for narrower frets, while the opposite side is optimized for wider ones. This dual-width feature ensures versatility and enables you to work with different fret sizes effortlessly.
The full-length concave filing grooves on both sides of the file are uniformly coated with micro industrial-diamond particles. This innovative coating enhances the file’s longevity and sharpness, resulting in superior cutting performance. Unlike traditional fret files, which often produce unwanted chatter marks, the diamond particles on this file enable smooth, chatter-free operation. As a result, your frets will not only be accurately recrowned but also left noticeably smoother and more refined.
Measuring at 8-1/2″ in length, 1″ in width, and 5/32″ in thickness, this file offers optimal size and weight for precise control and maneuverability. Its ergonomic design ensures a comfortable grip, allowing you to work on frets with ease.
Utilizing the 300 grit file enables you to achieve properly crowned frets in a matter of strokes. The grit’s medium coarseness strikes the perfect balance between material removal and precision, making it an excellent choice for efficient fret dressing.
