Value Collection 210-3067 End Mill Holder NMTB30

Product Description

The VALUE COLLECTION 210-3067 is an end mill holder designed for milling machines equipped with an NMTB30 taper spindle. It accepts a 3/16 inch bore and provides 1.75 inches of projection, positioning the cutting tool at the correct standoff from the spindle face. The nose diameter measures 11/16 inch. With a total indicator runout (TIR) of 0.0004 inch, this holder maintains tight concentricity for accurate milling operations. A 1/2-13 drawbar thread secures the holder to the machine spindle. Machinists and CNC operators in job shops, maintenance departments, and production environments use this holder for standard end milling applications.

This end mill holder is suited for vertical milling machines, knee mills, and machining centers with an NMTB30 taper spindle. The 3/16 inch bore accommodates small-diameter end mills commonly used in detail work, slot milling, and contouring operations. The 1.75 inch projection gives adequate clearance for most standard milling setups. No through-coolant port is included, making this holder appropriate for dry cutting or flood coolant applications where coolant is directed externally.

Key Features

• NMTB30 taper shank for direct spindle mounting on compatible milling machines
• 3/16 inch bore diameter for small-diameter end mill shanks
• 1.75 inch projection for standard tool standoff clearance
• TIR of 0.0004 inch for consistent concentricity and surface finish
• 1/2-13 drawbar thread for secure spindle retention
• 11/16 inch nose diameter

Compatibility

Designed as an OEM-style replacement or standard tooling addition for milling machines equipped with an NMTB30 taper spindle interface.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine powered down and the spindle fully stopped. The drawbar must be tightened to the machine manufacturer's specified procedure before operation. Inspect the taper shank and spindle bore for debris or damage before seating the holder. Do not exceed the machine spindle's rated speed for the tool and holder combination in use.
