Image showing a basic drill cage with an adapter labeled RB 356 HP 58 / RB 356 HPI 58, and two mounting base flat bearings, one labeled 90815140W and the other 90815140.

This drill cage has been designed for use with cutter of 7/8" to 1.1/2" dia.
Different mounting bases available.

        Detachable spindle adaptor Jacobs No 1 taper provides alternative methods for use:
        In combination with 3 jaw chuck using 10mm | 0.39" shank.

                Mounting direct onto machine spindle using Jacobs No 1 taper. 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.
            

    
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. This patented feature allows an easy loosening of the locknut without damage to the drill cage.
