Milwaukee Thunderbolt pilot bits are designed for extreme durability and long life

The Thunderbolt web features a thicker core than a standard pilot bit, which provides strength and protects against side-load breakage

A specially designed parabolic flute form clears chips and debris fast to keep the bit cool

A precision start, 135 deg

split point tip starts on contact to keep the bit from walking for fast, accurate holes

Excellent for drilling on curved surfaces, requires less effort to drill, and is highly for use with portable drills
