Piloted Aircraft Microstop Countersink Cutter 5/16” x 100 x 3/16” Description

Piloted aircraft stop countersink cutters (often called micro-stop cutters, or microstop countersinks) are used to make precision countersinks to accept flush-head fasteners. 5/16” body diameter, high speed steel, 100°, 1/4-28 thread. Typically used for countersinking holes for 1/8” (6-32) or smaller diameter fasteners. The head diameter of the flush fasteners must not exceed 5/16” to insure proper seating of the screw.

Omega Technologies countersink cutters are precision ground to exact tolerances to insure concentricity. Countersink cutters may be used in any micro-stop ”cage” that accepts 1/4 – 28 threaded shank cutters.
