Value Collection 230-7203 Collet Chuck 1 in Full Grip NMTB40

Product Description

The VALUE COLLECTION 230-7203 is a full grip collet chuck designed for precision machining operations on milling machines and machining centers. It accepts collets up to 1 inch capacity and mounts via an NMTB40 taper shank for secure, repeatable tool holding. The chuck delivers a total indicator runout (TIR) of 0.0006 inches, supporting close-tolerance work where concentricity matters. Weighing 2.96 pounds, it is built for shop environments where reliable grip and accurate tool positioning are required on every setup. Machinists, tool-and-die workers, and CNC operators are the primary installers and users of this chuck.

This collet chuck is suited for use on NMTB40-spindle vertical and horizontal milling machines in both job shop and production environments. It works with full grip collet systems to distribute clamping force evenly around the tool shank, reducing tool pullout risk during heavy cuts. Typical applications include end milling, drilling, and reaming operations where a secure, low-runout connection between the spindle and cutting tool is critical to part quality.

Key Features

• 1 inch maximum collet capacity accommodates a wide range of standard tool shanks
• Full grip collet system distributes clamping load evenly around the tool for reduced pullout
• NMTB40 taper shank for direct mounting to compatible machine spindles
• 0.0006 inch TIR supports close-tolerance and finish machining operations
• Compact at 2.96 pounds for straightforward tool change handling

Compatibility

Designed as an OEM-style replacement or direct-fit accessory for milling machines and machining centers equipped with an NMTB40 taper spindle and compatible with full grip collet systems up to 1 inch capacity.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the chuck. Inspect the taper bore and chuck taper for chips, nicks, or contamination before seating — any debris will affect runout and can damage the spindle. Torque the drawbar to the machine manufacturer's specification and verify TIR with a dial indicator after installation before beginning cuts.
