Irwin 81160 #60 High Speed Steel Wire Gauge Drill Bit, 1-5/8 In.

The Irwin 81160 #60 High Speed Steel Wire Gauge Drill Bit is a precision jobber-length drill bit designed for exact-size hole drilling in tapping applications. This #60 wire gauge bit (0.04 inch diameter) is engineered for use in automotive repair, maintenance and restoration (MRO), and production environments where non-fractional sized holes are required. Whether you're working with a portable drill or a stationary drill press, this bit delivers consistent, accurate results across a wide range of materials and applications.

Tapping requires precision-sized pilot holes, and this wire gauge bit is sized to produce the exact hole diameter needed for proper tap engagement. The high-speed M-2 steel construction provides exceptional heat resistance and wear resistance, allowing the bit to maintain its cutting edge through demanding drilling tasks without dulling or breaking prematurely. Its straight shank fits standard drill chucks for quick bit changes.
