RUKO Drill Chuck Arbor MT3 to B16 for 16mm Drill Chucks

This RUKO GMBH drill chuck arbor provides a rigid, self-holding connection between a Morse Taper MT3 machine spindle and a B16 taper-bore drill chuck. Its hardened and ground tool steel construction delivers the concentricity that professional workshops demand when mounting 16mm drill chucks.

Highlights

• Machine side: Morse Taper MT3 (MK3)
• Chuck side: B16 taper
• High-grade tool steel, hardened and ground
• Self-holding taper with tang drive for secure mounting
• Precision ground surface, lightly oiled for corrosion protection

In daily use

The arbor seats firmly in the spindle taper and the chuck taper, transmitting torque without slippage. The tang engages the spindle slot to prevent rotation during heavy drilling, while the drift slot allows easy removal with a standard drift key.
