Our tempered edge-cut nut files produce round-bottom slots, to ensure that the strings seat properly in the nut without buzzing. Each chrome-alloy steel file has twin 4" cutting edges. Among our most popular tools, these professional files help you get the job done quickly and correctly.
Standard widths: .010" thru .056" Nut files for bass: .065" thru .105"
TIP: A nut file can be rocked back and forth while cutting, to form a slightly wider slot when necessary.
