These custom-made files give you a handle on your fret work! These files work quickly to level frets or fingerboards, leaving a smooth finish. This file is 1" x 6" length and is for general use.The fret leveling file has single-cut teeth with a steeper angle to eliminate "chatter." They cut faster and smoother than most fret leveling files we've used, they work quickly, and they're great for dressing and beveling fret ends. Works on stainless frets, too!This tool is suitable for use on stainless-steel fretwire. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.
