The Cleco 10040720 RB 356 HPI 21 Microstop Cage, Mounting Base Flat Bearing Small Window features a cemented, hardened and ground chrome-nickel steel spindle mounted on 3 needle-bearings and a thrust bearing. Microstop depth adjustment (1 scale division = .001”). Microstop depth setting is held securely in place by locknut with seal.

Detachable spindle adaptor provides alternative methods for use:

• In combination with 3 jaw chuck.
• Mounting direct onto machine spindle using No. 1 Jacobs taper or 3/8”-24 Threaded Input Option: This method provides increased level of concentricity, while reducing the length and weight of the drill / tool assembly. This results in better performance, improved machining and less fatigue on the operator.
