Low-friction files for fret ends. The Fret Beveling File is the fast, accurate way to put a uniform 35° bevel on fret ends after installing new frets. With a quick, smooth motion, this file angles the fret ends and makes them ready for fret dressing and polishing. This 1-1/2" x 1-3/4" block (filing length is 3-3/4") holds a removable fine-tooth flat file at the proper 35-degree angle to bevel all the fret ends along the edge of the fingerboard. The 3-3/4" model is for short fingerboards (mandolins, for example), and for spot-filing partial refrets. It's also useful for working on used instruments with necks that aren't straight. The block is made of low-friction material for smooth, easy filing. This product is made exclusively for Stewart-MacDonald by Brown's Guitar Factory. Works on stainless frets, too! 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. Instructions included.
