Milwaukee 49-56-8000 High Speed Steel Pilot Bit 1/4" x 4"

Milwaukee Thunderbolt pilot bits are designed for extreme durability and long life. The Thunderbolt web has a thicker core than a standard pilot bit, delivering ultimate strength and protection against side-load breakage. A specially designed parabolic flute form clears chips and debris fast to keep the bit cool. The precision-start 135 split point tip starts on contact and keeps the bit from walking for fast, accurate holes. It excels at drilling on curved surfaces, takes less effort to drill, and is highly recommended for use with portable drills.
