Main Product Description
The Leitz HSK63F Shrink Fit Chuck L37710 is developed for CNC machining centers requiring a rigid, concentric connection between the spindle and cutting tool. Inductive heating expands the 20 mm clamping bore for tool insertion; controlled cooling then creates uniform radial clamping around a compatible h6 cylindrical shank.
The toolholder combines a 75 mm gauge length with a 100 mm body length to provide useful reach while maintaining a slim external profile for machining clearance. Its monoblock premium hot-work-steel construction helps control vibration and supports stable retention during high-speed routing, profiling, nesting, and edge-machining operations.
The supplied specifications identify runout accuracy of less than or equal to 0.003 mm and fine balancing to G2.5 at 24,000 RPM parameters. When installed and maintained correctly, this configuration supports precise use of compatible 20 mm solid-carbide or PCD tooling shanks while helping protect cutting edges, spindle bearings, and finished-part quality.

Product Highlights
Low-Runout Toolholding
The monoblock HSK63F construction supports concentric tool retention and helps reduce vibration at high spindle speed.
Slimline Machining Access
The 75 mm gauge projection and streamlined body improve clearance for deeper profiles and complex CNC toolpaths.
Compatibility & Installation Notes
Use only with compatible HSK63F spindle receivers, approved 20 mm h6 cylindrical tool shanks, and a dedicated induction-heating system suitable for steel shrink-fit chucks. Operators must be trained in thermal clamping procedures. Keep the HSK contact faces and clamping bore clean, follow the specified heating and cooling cycle, and verify tool seating, balance, runout, and machine-speed limits before operation.
Strengthen the Spindle-to-Tool Interface
The Leitz HSK63F Shrink Fit Chuck L37710 provides a rigid thermal-clamping interface for precision CNC production. Its 20 mm bore, 75 mm gauge length, 100 mm body length, and HSK63F spindle connection support compatible solid-carbide and PCD tooling used in demanding routing and profiling applications.
Premium hot-work-steel construction, low-runout retention, and G2.5 balancing help improve cutting stability, surface quality, and tooling performance when the chuck is heated, installed, cooled, and maintained according to approved operating procedures.
