Milwaukee THUNDERBOLT Black Oxide Drill Bit Set 29PC

The 29 Piece Thunderbolt? Black Oxide Set offers incredible durability and longer working life by means of the rust-resistant oxide coating and the thick Thunderbolt web core. A parabolic fluting pattern allows the black oxide drill bits to drive chips and other debris away to vastly reduce friction and heat for protection and to maintain the bits’ shapes. The 135-degree split-point bit tip starts a hole as soon as it hits the drilling surface to prevent walking and damage to your workpiece. These black oxide kits come with bits that range from 1/16-inch to 1/2-inch in 1/64-inch increments to drill virtually any hole that your project requires. A 3-flat shank with secure grip design stays put for straighter holes and damage-free operation. The bits fit 3/8-inch chucks.
