The 135° split point is self-centering to reduce walk-off, which can make drilling more precise and faster—especially helpful when you’re starting holes in stainless steel or cast iron. A fully ground twist design helps clear chips efficiently, reducing friction and heat for cooler performance.
You get 13 common fractional sizes from 1/16″ up to 1/4″, stored in an orange plastic case with a size index so it’s easy to keep everything organized and grab the right bit quickly.
