Welcome to the "Side Show”
Competitive Carbide is pleased to introduce the latest in form drilling technology. Our patent pending “Helmet Head” system gets from centerline out to the first diameter, while the rest of the tool addresses as many features of your part as possible.

With our patent pending Helmet Head System, we can provide the cut of a solid step or form drill with the interchangeability of an indexable tool. Whether for straight hole applications or for drill & countersink/counterbore application, the Helmet Head System offers an affordable option to solid carbide drills over Ø10mm.

In both Aluminum and Cast Iron, “Helmet Head” incorporates a dual margin drill tip. This allows you to hold accurate sizes, drill straighter holes, and burnish the diameter for a smoother finish.
