Value Collection 230-7211 NMTB30 Full Grip Collet Chuck Set

Product Description

The VALUE COLLECTION 230-7211 is a full grip collet chuck set built on an NMTB30 taper shank, designed for use with 1 inch series collets in machining centers and milling applications. The NMTB30 taper provides a secure, repeatable connection to the machine spindle, while the full grip collet design maximizes radial contact on the tool shank for improved concentricity and reduced runout. At 11 pounds, this is a substantial tooling set suited for production environments where rigidity and consistent clamping force are required. Installation and setup are typically handled by machinists and toolroom technicians working with vertical or horizontal machining centers.

This collet chuck set is intended for use in machine tool setups requiring an NMTB30 taper interface. The 1 inch series collet system accommodates a range of tool shank diameters within that series, making it a versatile choice for shops running multiple cutting tool sizes on NMTB30-equipped spindles. Typical applications include milling, drilling, and reaming operations in job shop and production machining environments. The full grip collet format is preferred in applications where standard ER-style collets do not provide sufficient clamping rigidity.

Compatibility

Designed for machining centers and milling machines equipped with an NMTB30 taper spindle and configured for use with 1 inch series full grip collets.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the collet chuck. Inspect the taper shank and spindle bore for contamination or damage before seating the chuck, as debris will affect concentricity and tool life. Follow the machine tool manufacturer guidelines for drawbar torque and collet nut tightening procedures.
