The Micrometer Micro Stop-Countersink Units developed for the aircraft industry to allow precise
depth control countersinking and deburring. These units ensure perpendicular alignment with the
work piece and easy to adjust exact depth control in increments of .001".
They feature hardened and ground spindles supported by ball bearings, bronze sleeves, or needle bearings,
and thrust bearings, and a lock nut to maintain "preset" depth dimensions.
Overhang is at a minimum making it possible to work in close quarters widely used in Aircraft manufacturing and maintenance,
in sheet metal part production areas, and have found wide use in Transportation, electronic, medical, defense,
and telecommunications where precise depth control counter- sinking is required.
Used in hand drills, drill presses, mills, lathes, etc.
Bases can be modified for special applications or contours. See high speed roller bearing units RSC-24 & RSC-36
