Precision R8 Chuck for CNC Machining
The Jacobs 31411 JK 130-R8 is a keyless drill chuck designed for CNC machines with an R8 taper mount. It accepts drill bits up to 13 mm capacity and is built for high-torque applications requiring precise tool holding.
High-Torque Grip Under Continuous Load
The chuck maintains clamping force during sustained heavy drilling cycles thanks to its high-torque design and HAWA material construction. Keyless operation allows rapid bit changes without interrupting workflow on production equipment.
R8 Taper Limits Bit Capacity to 13 mm
The R8 mounting interface restricts maximum drill diameter to .5120 in, so larger tooling requires a different taper standard. Users needing capacity beyond 13 mm must select a chuck with a larger mount such as Morse taper.

Questions about this item
How much heat does the Jacobs 31411 chuck generate during continuous drilling?
The chuck is a mechanical component with no motor or electronics, so it produces no heat of its own; any warmth comes from the drill spindle and cutting action.
What spindle interface must my machine provide for the R8 mount on this 13 mm chuck?
The chuck requires a standard R8 taper socket on the machine spindle; no draw-bar or additional hardware is included with the chuck itself.
Will the .5120 in capacity of the 31411 chuck accept the same shank sizes as my older 1/2 in keyed chuck?
The maximum capacity is .5120 in (13 mm), which is marginally larger than 1/2 in, so it will hold every bit your old chuck accepted plus a few slightly larger shanks.
