Value Collection 230-7215 NMTB40 Collet Chuck Set

Product Description

The VALUE COLLECTION 230-7215 is a full grip collet chuck set built on an NMTB40 taper shank, designed for use in CNC machining centers and manual milling machines that accept the NMTB 40 taper interface. The set uses the 1-1/4 inch collet series and delivers a full grip collet design that provides uniform clamping force along the full length of the collet for consistent tool retention and reduced runout. At 21 pounds, this is a multi-piece set suited for machine shops running moderate to high production work where tool-holding consistency is critical. Installation is performed by qualified machinists or toolroom technicians.

Full grip collet chuck sets in the NMTB40 taper configuration are commonly used in vertical milling machines and machining centers found in both job shop and production environments. The NMTB40 taper shank seats directly into the machine spindle and is secured with a drawbar. This set is appropriate for operations requiring reliable tool holding across a range of cutting tool shanks compatible with the 1-1/4 inch collet series, including end mills, drills, and reamers used in ferrous and non-ferrous material cutting applications.

Key Features

• NMTB40 taper shank for direct spindle mounting on compatible milling machines and machining centers
• Full grip collet design provides uniform radial clamping force for reduced tool runout
• 1-1/4 inch collet series accommodates a range of cutting tool shank diameters
• Multi-piece set configuration supports toolroom setup and production changeovers
• Substantial 21-pound set weight indicates robust, production-grade construction

Compatibility

Designed for use with milling machines and machining centers equipped with an NMTB40 taper spindle and drawbar retention system that accept the 1-1/4 inch full grip collet series.

Installation Notes

Installation of collet chuck sets should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing any taper shank tooling. The NMTB40 taper and spindle bore must be clean and free of chips, oil, and debris before seating the shank to ensure proper contact and safe retention. Torque the drawbar according to the machine manufacturer specifications and verify tool runout with a dial indicator before beginning cutting operations.
