Engineered for Rigidity, Sealed Coolant Flow, and Micron-Level Accuracy—at a Decent, Reasonable Price!
Upgrade your CNC machining center with these premium spring collets, manufactured to strict DIN 6499-B / ISO 15488 standards. Whether you are boring, milling, drilling, tapping, grinding, or engraving, this collet delivers the performance stability and high accuracy your critical jobs demand. Constructed from high-grade 65Mn spring steel with a hardened surface up to HRC 55, it offers exceptional wear resistance, high elasticity, and a formidable grip.
🔍 PRECISION YOU CAN COUNT ON
Each collet is individually inspected on a high-tolerance bench-marked test rod at 4 distinct contact points, guaranteeing an ultra-precision test runout of 0.0002" (5μm) . In standard operational clamping, you can depend on a reliable working accuracy of 0.0003" – 0.0004" T.I.R. This ensures your workpiece remains accurately positioned and stable throughout the machining process.
💧 NEXT-GEN COOLANT-THRU DESIGN (NO PLUGS NEEDED!)
Say goodbye to loose sealed plugs and complicated coolant discs! Our unique, patented design integrates precision-machined coolant slots directly within the collet. This allows for seamless, high-pressure coolant delivery up to a maximum of 1500 PSI, effectively flushing chips away from the cutting zone while protecting your tool holder from contaminants.
⚙️ UNMATCHED RIGIDITY & BALANCE
Featuring special angled slots, this collet drastically increases overall rigidity. The superior design ensures a better-balanced tool holder assembly, reduces harmful vibration, and extends the life of both your cutting tools and your machine's spindle.
📐 IMPORTANT USAGE NOTE FOR OPTIMAL PERFORMANCE
To ensure zero leakage and maximum holding force, this collet is designed for use with on-size (nominal) shank diameters ONLY. While it can physically clamp non-nominal sizes, you may experience minor coolant seepage. For best results, always confirm your tool shank matches the collet range exactly.
