Extend the reach of solid carbide and HSS cutting tools into deep, narrow cavities using high-precision Shrink-Fit Chuck Extensions. Engineered specifically for deep-pocket die & mold manufacturing, 5-axis contouring, and restricted-access CNC milling, these straight-shank extension rods feature a slim, tapered thermo-shrink clamping nose. Held within standard collet chucks, hydraulic chucks, or base shrink holders, they utilize thermal contraction to grip tool shanks with $360^\circ$ uniform radial force, maintaining sub-micron runout accuracy and superior dynamic balance at high spindle RPMs.
