This bevel diamond fret file (made from aluminum with durable diamonds) is an economical fret crowning tool that works on any fret size. Its beveled surface with diamonds will file the sides of frets and preserve the top, saving you from extra fret leveling work.
Available in 400 grit (S-T229-400) and 200 grit (S-T229-200):
The 400 grit is recommended if you are new to doing fret work because it doesn't remove as much material as quickly as the 200 grit. The 200 grit can mill off material more quickly and lasts longer.
