About this item

Milwaukee® Thunderbolt® Hole Saw Arbor Pilot Drill Bit, Tapered, 3-Flat Shank, 1/4 in Diameter Hole Saw, 4 in Overall Length, 1/4 in Cutting Depth, Parabolic Flute, 135 deg Point, Split Point, HSS Cutting Edge, HSS, Applicable Materials: Metal and Wood

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 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, 135º 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 recommended for use with portable drills.
