Milwaukee Tool High Speed Steel Pilot Bits are designed for extreme durability and long life. Thunderbolt pilot bits have a thicker core than a standard pilot bit, which provides ultimate strength and protects against side-load breakage. The tapered web resists breaking and the parabolic flute clears chips faster for more efficient operation. The 135? split point provides a precision start for accurate hole placement and no walking.
