.0280"–.0330" / #70–#66 Carbide Drill Bit Set – 1/8" Shank – 10 Pc – S5

This S5 carbide drill bit set includes ten solid carbide drill bits in five useful small sizes, ranging from .0280" to .0330" / #70 to #66. The set includes two pieces of each size, making it a practical assortment for PCB drilling, electronics work, model making, carburetor jet work, and other precision 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 small carbide drill bits that can break if pushed too hard, run with poor alignment, or used in an unstable setup.
