Description
The Techniks 31376-E HSK40E ER16 collet chuck delivers precision clamping for HSK40E spindles in CNC machining centers. This HSK40E ER16 collet holder with a 65 mm projection provides a 65 mm gauge length for deep reach and controlled tool clearance. Constructed from 8620 steel with precision machining, the Techniks HSK40E tool holder steel resists wear and maintains concentricity. The ER16 CNC collet chuck supports a capacity range of 0.5–10.5 mm for common ER16 collets used in finishing and light roughing. Techniks balances the 31,376-E to 25,000 RPM at G2.5 for stable high-speed operation in demanding spindle environments. Overall length and body diameters are optimized for HSK40E interfaces to minimize runout between the taper and the collet pocket. A TIR specification of 0.0001” measured from taper to collet pocket ensures repeatable precision in tool holding. The Techniks HSK40E spindle collet chuck includes a high-clamping nut and features to improve collet retention under torque. The 31376-E ER16 collet chuck is single-ended and compatible with standard ER16 collet series for tooling flexibility. Its robust design supports both metric and inch tooling units across milling and drilling operations. Technical shops value the combination of low TIR and balanced construction for surface finish and tool life improvements. The ER16 CNC collet chuck HSK40E 65mm length provides a good compromise between reach and rigidity for many setups. Maintenance is straightforward: inspect the taper and collet surfaces for cleanliness and replace collets when wear increases runout. Techniks 31376-E is ideal for precision ER16 tooling and HSK40E setups requiring repeatable concentricity and high RPM capability. Select this Techniks HSK40E ER16 collet chuck when you need accurate, high-speed toolholding for compact CNC toolpacks.
