Value Collection 230-7212 NMTB40 Collet Chuck Set

Product Description

The VALUE COLLECTION 230-7212 is a full grip collet chuck set built on an NMTB40 taper shank, designed for use with 1-inch series collets. The full grip design provides secure clamping force across the collet body, reducing tool runout and improving concentricity during milling, drilling, and boring operations. Weighing 12.25 pounds, this set is suited for knee mills, CNC machining centers, and manual milling machines that accept NMTB40 tooling. Machinists, tool room technicians, and CNC operators are the primary installers and users of this type of tooling system.

This collet chuck set is intended for use in machine shop environments where NMTB40 taper tooling is the standard. It is appropriate for both production machining and general-purpose tool room work. The 1-inch collet series accommodates a range of cutting tool shank diameters within that series. Applications include face milling, end milling, and similar metal-removal operations on vertical milling machines equipped with an NMTB40 spindle taper.

Compatibility

Designed for use with milling machines and machining centers equipped with an NMTB40 spindle taper and compatible with 1-inch series full grip collets.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Always power down and lock out the machine spindle before mounting or removing tooling. Use the appropriate draw bar and spanner wrench for the NMTB40 taper to ensure proper seating and secure retention. Inspect the spindle taper and chuck taper surfaces for nicks or contamination before mounting.
