Microstop Cages Microstop Countersink Cages provide precise depth control by limiting the travel of the cutter being used, and aiding in the alignment of the cutter so that it is exactly perpendicular to the surface against which the cage rests. All microstop countersink cages units feature hardened and ground spindles. These are supported by bronze bushings (for general use), or needle bearings and ball bearings (for more demanding high-speed applications). Thrust bearings provide axial support while the micro-adjustment offers precise depth control. Microstop countersink cages may be ordered with a variety of foot-pieces and skirt styles. ATI Microstop Cages Recognized throughout the industry, ATI microstop cages are designed to provide precise depth control by limiting the travel of the cutter being used, and aiding in the alignment of the cutter.

Microstop Cages are specialized tools used in the aerospace industry to ensure precision and accuracy during the drilling of holes in aircraft components. They are designed to hold drill bits and ensure that the holes are drilled to the exact depth required for the specific fastener being used.

Microstop Cages consist of a small metal cage that is placed around the drill bit. The cage has an adjustable stop that limits the depth to which the drill bit can penetrate the material being drilled. This ensures that the holes are drilled to the exact depth required for the fastener being used, which is essential for maintaining the strength and integrity of the aircraft component.

The adjustable stop on the Microstop Cage can be set to any depth within the range of the cage. This allows for precise control over the depth of the hole being drilled, which is important when working with materials of different thicknesses or when drilling in tight or hard-to-reach spaces.

Microstop Cages may be used in a variety of applications, such as drilling holes for rivets, screws, or other fasteners in aircraft components like wings, fuselage panels, or engine components. They are designed to be used with a variety of different types of drills, including hand drills, pneumatic drills, and electric drills.

Microstop Cages are an essential tool for ensuring precision and accuracy in the drilling of holes in aircraft components. They help to ensure that holes are drilled to the exact depth required for the specific fastener being used, which is critical for maintaining the safety and integrity of the aircraft.
