Cutter Thread M6 X 1

Comparison image of various drill cages and adapters under 'Large Window' and 'Small Window' categories. Includes threaded bases, offset mounting bases, and vacuum options. Top features a basic drill cage adapter.

Different mounting bases available.
For composites mounting base with vacuum.
High precision microstop cage, body in heat treated chrome steel, fully ground throughout. This ball mounted microstop cage includes two needle bearings for best utilisation.
When using the RB 257, any misalignment of the microstop cage is corrected by the unique ball pivoting spindle. This assembly ensures perpendicularity throughout the operation at all time.
Centring-cone of the cutter (120°) for perfect concentricity.
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 lock-nut without damage to the drill cage.
