.0210"–.0260" / #75–#71 Carbide Drill Bit Set – 1/8" Shank – 10 Pc – S4

This S4 carbide drill bit set includes ten small solid carbide drill bits in five useful micro sizes, ranging from .0210" to .0260" / #75 to #71. The set includes two pieces of each size, making it a practical small-drill-bit assortment for precision work, PCB drilling, model work, carburetor jet work, and other delicate drilling applications.

Choose new, lightly used, or factory resharpened drill bits using the condition selector. These are solid carbide drill bits with 1/8" shanks and 1.50" overall length. Flute lengths are .220" minimum.

The two-pieces-per-size format gives you a backup drill bit in each size, which is helpful with very small carbide drill bits that can be fragile if pushed too hard, misaligned, or used in an unstable setup.
