    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.

    Adapt CNC machines with CAT 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. They meet ANSI/ASME standards for CAT spindles to ensure compatibility. Internal threads on the shank let you attach a retention knob, so you can connect them to your machine’s drawbar system.
    Slide your tool into these adapters and then press firmly to seat it. To separate them, use a Morse taper removal tool.
