    Drill Chucks with NMTB Taper Integral Arbor

    Image of Product. Top orientation. Drill Chucks. Drill Chucks with NMTB Taper Integral Arbor.
    Limit runout and slippage under heavy cutting forces from manual mills and older CNC mills. These chucks have an integrated arbor for a one-piece design that makes them more accurate and compact than chucks with a separate arbor. Made of hardened steel, they resist wear from repeated use. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet ASME standards for compatibility across machines with NMTB spindles. They're also compatible with older Erickson quick change spindles. Internal threads in the shank connect to your machine's drawbar.
    Twist the sleeve by hand to swap bits out quickly. The grip on the bit tightens as torque increases.
    To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.

    NMTB Taper Collet Chucks

    Image of Product. Front orientation. Milling Machine Collet Chucks. NMTB Taper Collet Chucks.
    Hold collets tightly in older CNC machines with NMTB taper spindles for milling, drilling, and routing. The shank on these chucks is precision ground to the industry standard AT3 tolerance—or better—for a secure fit that minimizes runout in your machine spindle. Internal threads in the shank connect to your machine's drawbar.
    Insert your collet and tighten the nut to clamp your tool in place.
    To maximize grip and minimize runout, choose a chuck where your tool diameter falls in the middle of the bit shank size range.
    Collet Stop Screw—Chucks with a collet stop screw set the tool depth in the chuck for consistent, repeatable performance when you change tools.
