About Micrometer Stop Units

Severance Precision Stop Countersink Units (the Micro-Stop system) hold a threaded SC stop-countersink cutter and set its depth of cut, adjustable without tools in 0.001" increments; the SC-25P, SC-25PR, SC-35P and SC-35PR units give 0.0005" per click. Units have a 1/4", 3/8" or 1/2" shank for hand power tools and drill presses, and every unit comes with a positive stop lock nut and a SecurLock safety screw to hold the preset depth. The base sets the cutter perpendicular to the work; oversize or modified bases and special override units are available by application, and non-marring nylon feet protect the work finish.

Cutters are sold separately: see the HSS and carbide stop-countersink cutter pages. U.S. Patent 3028774.
