Slim Hydraulic Chuck for Narrow Workpiece Applications

NT Tool’s hydraulic chucks in the slim-bodied PHC-S holder are especially useful for tight spaces.

NT Tool’s hydraulic chucks in the slim-bodied PHC-S holder are especially useful for tight spaces. These PHC-S holders combine the stability and precision of NT’s dual clamping-point system with the access into narrow workpieces previously only possible with shrink fit holders.

Like all NT hydraulic chucks, the PHC-S model provides 3-micron accuracy. The oil chamber around the chucking sleeve absorbs cutting vibrations in a way that the solid metal body of shrink fit holders cannot, which allows for consistently higher accuracy and a smoother work surface. An electro-magnetic rust-proof coating—standard for most NT holders—ensures that this accuracy is maintained throughout the life of the holder.

Setup is designed to be quick and easy, requiring nothing more than a one-handed hex wrench to clamp the cutting tool. This allows for minimal downtime and eliminates the risk of burn injuries associated with shrink fit chucking, making the PHC-S a compelling alternative for all tight-space applications, the company says.

The PHC-S is available in HSK, CAT (standard and two-face contact), BT (standard and two-face contact), and UTS shank styles. They are offered in both inch sizes (1/4” and 1” diameters) and metric sizes (6 mm – 25 mm diameters), and custom sizes are readily accommodated.
