Milwaukee 1/4in x 4in HSS Pilot Bit for Long Arbor Hole Saws

This High Speed Steel Thunderbolt pilot bit is designed for extreme durability and long life. The Thunderbolt web features a thicker core than a standard pilot bit, which provides ultimate 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° split point tip starts on contact to keep the bit from walking for fast, accurate holes. Excellent for drilling on curved surfaces as it requires less effort to drill.
