NMTB Taper to Morse Taper Shank Adapters
 |
 |
Adapt older CNC machines with NMTB taper spindles to mount tools with a Morse taper shank, including drill bits, drill chucks, and reamers. These adapters are made of hardened steel to resist wear. Their shank is precision ground to the industry standard AT3 tolerance for a secure fit that minimizes runout in your machine spindle. Internal threads in the shank connect to your machine's drawbar. These adapters meet ANSI standards for compatibility across machines with NMTB spindles. They're also compatible with older Erickson quick-change spindles.
Slide your tool into these adapters and then press firmly to seat it. To separate them, use a Morse taper removal tool.
