Super Tite-Lock Milling Chuck ( CT-S Type ) Finish and heavy milling ③ 2 Stage Tightening for finish and heavy milling Seal ⑤ Double seal Seal ・Prevent the cir-clip coming out during high-speed rotation. ・Perfect w sealing makes longer life. ① Deep groove slot ・High clamping torque Slim outer diameter same as CT-A type ④ Without groove ・Center thru coolant as well as jet coolant. ② T-slot groove ・Slippage and pull out of cutting tools.

Advantage 1 T slot + Deep groove slot heavy milling Deep groove slot ・ High clamping force T slot Deep groove slot High clamping force Reducing micro vibration which results in stable heavy cutting

Advantage 2 NT original patented T slot design minimizes slippage and pull out ! Axial direction slot Radial direction slot Axial direction slot Shank Tool shank Cutting tool Cutting tool Prevention of slippage Prevention of pulling out NT Original T slot prevents slippage and pull out of cutting tools, suitable for roughing applications !

Advantage 3 2 stage clamping for roughing and finishing! Black ring Clamping for High rigidity ・STAGE ONE! Finish milling : Tighten clamping ring till the black area is not visible. ・STAGE TWO! Heavy milling : Tighten clamping ring up to the maximum torque.

Advantage 4 Center thru coolant as well as jet coolant With NT specially designed MC-OH and MC-C collets, capable to make a thru coolant and jet coolant operations.

Advantage 5 Unique retaining ring allows speeds up to 20,000rpm. Prefect W sealing makes longer life. Cover for prevention centrifugal force. Resin seal Rubber seal Cir-clip To make cover ring on the cir-clip, this prevents cir-clip expansion comes from the centrifugal force. It’s capable to use up to 20,000rpm ! Normal milling chucks is not possible to use more than 12,000rpm.
