Each bit features a 135° split point for easier starts and a right-hand cut, spiral-fluted design that helps evacuate chips up and out of the cut to reduce clogging. The gold oxide finish is typically used to identify cobalt tools, with performance similar to uncoated tools.
With a round shank, these bits fit a wide variety of toolholding systems—handy if you switch between different drills or chucks in the shop.
