Super Precision Short Keyless Drill Chucks with Integrated Shank
Compact construction
Drill chuck model SPX-13 with DIN-69871 ISO 40 shank is 67 mm longer than drill chuck NPU-13 with the same shank. Greater rigidity and precision.
Retension screw
Guarantees a perfect connection between the internal arbor taper and the external arbor taper.
Higher precision
The eccentricity is controlled by the single taper connection to the machine and no intermediate arbor is needed as with the standard drill chuck.
Maximum connection rigidity
The connection with a short Morse taper is the best due to its ridigity and precision.
Features
- Maximum total integrated run-out of 0,04 mm (.0016”).
- For use on CNC machining centres.
- Single taper connection between drill chuck and shank eliminates intermediate arbors to ensure high tool rigidity and drilling accuracy
- Furnished with milled wrench flats and spanner wrench to allow application of supplementary gripping torque
- Resistance to tool loosening on high-speed machines with instant spindle stop
