Albrecht Replacement Jaw Set for Keyless Chuck An Albrecht replacement jaw set for Albrecht keyless drill chucks — the hardened, precision-ground jaws that grip the drill shank and determine the chuck's gripping accuracy and tool retention performance. Jaw sets wear over time in production use; replacing the jaw set restores grip accuracy, reduces runout, and extends the service life of the chuck body without the cost of a complete chuck replacement. Albrecht jaws are ground to close tolerances and case-hardened for long service life. The self-tightening jaw geometry — the core of Albrecht's keyless design since 1932 — increases clamping force under cutting load, reducing tool pullout risk compared to standard three-jaw chuck designs. Made in Germany. Confirm compatibility with your chuck model before ordering.
