Starbide Carbide Countersinks

For use in Kevlar, Fiberglass, Boron, Plastic, Carbon and Other Highly Abrasive Materials

These solid carbide countersinks are manufactured in two geometric styles. Each style has been designed for use in specific type materials.

When a countersinking operation is to be performed in Kevlar or Fiberglass, the tool requires a special flute design in order that a clean fuzz-free edge may be generated.  The other tool style available is designed to be used in materials such as aluminum, titanium and graphite composites.

The tools are manufactured with a standard thread design to be operated in a standard micro-stop cage unit.

Both styles of countersinks are manufactured standard with an integral pilot design; also available on customer request are countersinks with through holes to facilitate a removable pilot.

These solid carbide countersinks have superfinished cutting edges and retain their original sharpness longer than conventional countersinks.

Material: Solid Micrograin Carbide.   Specifications: Drill D.A. +.0000 -.0003.
