For our chucks with female jacobs tapers, we offer male and female chuck adaptors. Our adaptors have a male jacobs taper and provide a snug fit to maintain accuracy in drilling. Our chuck adaptors also have through-holes with clearance up to 6 mm. Our adaptors give you the flexibility to choose whichever chuck suits your electrodes, not your machine.

Chucks and Precision

A chuck’s ability to hold an electrode with stability forms the basis of an EDM drilling apparatus. A chuck lacking precision only compounds defects in its electrode and guide, and does not wear down uniformly, reducing its lifespan. Keyless chucks have a much faster setup time than keyed chucks, increasing efficiency.
