Product Description
Milwaukee® THUNDERBOLT® black oxide jobber length drill bits are designed for extreme durability and long life. The THUNDERBOLT® web features a thicker core than a standard drill 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, requires less effort to drill and is highly recommended for use with portable drills.

- Jobber Style Drill Bit: The most common type of drill bit available. Jobber means "something that does a job" and mostly refers now to the length of the bit. Jobber drill bits are 9 to 14 times longer than the diameter of the bit. They can come in a variety of metal types and are good for drilling wood, iron and different types of steel.
