Step drills combine two different drilling diameters into a single tool! Step drills are very versatile, and can eliminate the need for two tools for specific applications. Creating a hole with a chamfer, countersink, or just drilling two diameters are all possible when Cougar designs your tooling!
Two-diameter Cutting Solution
Easy to Resharpen Tooling
Available with Coolant-Thru
PVD Coating for Added Tool-Life
Step drills are more complicated than a single diameter twist drill, but they can reduce the amount of tools used in making multi-diameter holes. Making a step drill from scratch is different from simply modifying a standard size to your needs. Not only can we customize the holding and coolant options for your application, we are able to design a tool that will manufacture more parts per tool than a modified standard.
