1/2'' x 100 Degree HSS Piloted Aircraft Microstop Countersink Cutters
1/2'' x 100° HSS Piloted Aircraft Microstop Countersink Cutters. 1/2'' body diameter, high speed steel, 100°, 1/4-28 thread are used to make precision countersinks to accept flush-head Fasteners and are used throughout the aviation industry.
Omega Technologies cutters are precision ground to exact tolerances to insure concentricity. Cutters may be used in any micro-stop ''cage'' that accepts 1/4 - 28 threaded shank cutters. Select the pilot diameter that matches the pre-drilled hole, and the body diameter according to the diameter of the fastener head. The head diameter of the flush fasteners must not exceed 1/2'' to insure proper seating of the screw.
Metric piloted aircraft microstop countersink cutters and other sizes not listed here, can be quoted on request.
