Features:

  • Ideal for use on jig borers, milling machines, lathes and radial drill presses.
  • Ball bearing construction maximizes gripping force and drilling accuracy.
  • Jaws are centerground for absolute straightness and alignment.

  • Tapered mount drill chucks have an internal Jacobs Taper (JT) that is press-fit onto a corresponding JT arbor (shank) or spindle.
  • Keyed chucks are engineered to either loosen or tighten the hold on a tool by using a key. Keyed chucks offer the advantage of applying additional torque on the bit when slippage is a concern during heavy-duty applications.
