From the Manufacturer

Milwaukee Silver and Deming Black Oxide drill bits are designed for extreme durability and long life. A special flute geometry 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. The 3-Flat, 1/2-Inch Secure-Grip shank won’t slip in the drill chuck.
