Set of 12 Round Smoothing Broaches-Size Range-0.68mm to 4.5mm

This set of 12 round smoothing broaches covers a size range of 0.68 mm – 4.5 mm, giving jewelers, watchmakers, and metalsmiths a comprehensive selection for cleaning and finishing holes in metalwork. Made of high-quality steel and uniformly tempered, these broaches are built for consistent performance and long service life.

These are English Pattern Broaches, sized according to the Stubs grading system — a measuring standard originating in England. The Stubs numbers correspond to markings from an English screw plate created by Peter Stubs of Warrington, Lancashire, a renowned maker of watch and clockmaking tools in the early 1800s. This system remains widely used in professional watchmaking and jewelry trades.

Please note: these broaches are sold as a set only and are not available for individual purchase.
