Microstop Cages

Apex offers Microstop drill cages in various sizes and configurations to suit specific application needs

Applications
Microstop drill cages are suitable for a wide range of applications in aerospace and other industries where accuracy is essential. When paired with a drill from the Dotco line of material removal tools and a cutter from the Recoules line of cutters, Microstop drill cages can be used for:
• Drilling — Microstop drill cages deliver high-precision drilling with perfect concentricity.
• Drilling and countersinking — Ball-type units are designed for perfect countersinking and spotfacing that is perpendicular to the bearing surface, in any hand position.
• Reaming and countersinking — An available tripod uses a pilot to position the cutter in the prehole, simplifying reaming and countersinking operations.

Features and Benefits
Microstop drill cages are precision-engineered to offer exceptional performance, long life and repeatability, even in difficult working conditions. These products incorporate advanced features that are not found on other drill cages, including:
• Microstop depth adjustment (1 scale division = .001”/.025mm ) with a patented seal-equipped locknut for safety locking — this prevents the locknut seizing allowing it to be easily loosened
• Hardened chrome-nickel steel construction with a self-lubricating bronze body and a ball thrust bearing - for extra durability
• Range of options for optimization to the application - anti mar on component surface; tripod bases for greater stability; integrated vacuum for reduce clean up; ball pivoting spindle to ensure perpendicularity
Select ball-type units also feature a removable adapter that can be used to fit directly onto the drill spindle without the use of a drill chuck. This later configuration minimizes the weight and length of the combined assembly, leading to reduced operator fatigue and greater productivity.
