Description
This PCD through-coolant step drill suits multi-stage holes in aluminum housings, valve bodies, and other non-ferrous components. It helps when separate drills make feature location harder to hold from step to step.
Step positions, coolant layout, entry form, chamfer relation, and shank standard can follow the actual bore stack instead of a generic stepped drill pattern.
