#1 thru #80 High Speed Steel Drill Bits.
Number drill bits also known as wire gauge drill bits fill the gap between fractional sizes, making them essential for tap drill sizing, precision hole work, and metalworking applications.
High-performance Hi-Molybdenum (M2) HSS wire gauge drill bits built to outperform standard HSS in accuracy, wear resistance, and tool life.
Available in sizes #1 through #80, these drills are used anywhere accuracy matters—from larger diameters (#1–#50) down to extremely small precision sizes (#51–#80).
We carry number drill bit sets and individual sizes across the full #1–#80 range—from micro number drill bits (#51–#80) to larger jobber length drill bits (#1–#50) used for accurate hole sizing, tap drill sizing, and general metal drilling.
Precision wire gauge drill bit sets are available in #1–#60 and #61–#80 ranges, covering both standard and micro-size applications.
