Severance Tool Industries, Inc. (Saginaw, MI) manufactures countersinks with one, four and six flutes, carbide and high speed steel, countersinks with pilots and drill points, heavy-duty tools and specials. Sizes range from 1/8" to 3", and almost any centerline angle can be specified.
These standard tools will handle at least 99% of all countersinking applications, and the company can build specials to satisfy any other need.
Severance countersinks are designed with staggered cutting edges, which inhibit the occurrence of resonant, or harmonic vibration. Chatterless design can’t change the natural frequencies of the system, but it takes tool geometry out of the problem.
What makes the Severance line unique is the number of proprietary and special tools it can supply to fit some specific applications:
- 3N1 Drill Points offer some cost-cutting opportunities to the creative tool engineer.
- CNC-K Precision Countersinks are used in numerical control and other preset tooling systems.
- Stop Countersink Systems are in wide use in the aircraft industry, where they are used with hand-held power tools to countersink rivet holes.
- Special Tools which combine countersinks with drills, steps, pilots, radii and other custom shapes are readily available from Severance. Just send in a sketch or description for quotation.
