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. Chucks with keys allow for a much tighter grip than keyless chucks.
