It accepts ER32 collets with a clamping range of 0.078 to 0.787 inches and mounts via a CAT50 taper shank for a rigid, repeatable connection to the spindle. Projection measures 4 inches from the gauge line, and total indicator runout (TIR) is held to 0.0002 inches, making it suitable for finish milling, drilling, and reaming operations where concentricity matters. Through-coolant capability supports both through-spindle and DIN flange coolant delivery to keep the cutting zone clear and extend tool life. The collet nut diameter is 1.97 inches. The chuck is balanced to 25,000 RPM for high-speed spindle applications.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is used on CAT50-spindle VMCs and HMCs in production and job-shop environments. It is well suited for shops running high-speed finishing passes, deep-hole drilling with coolant-through tooling, or any operation requiring minimal runout at the cutting edge. Installation and tool changes are performed by machinists and CNC setup technicians as part of standard tool crib management. The 4-inch projection provides clearance for medium-depth workpieces and fixtures without requiring an extension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER32 collet system accepts tooling from 0.078 to 0.787 inches in diameter\u003c\/li\u003e\n  \u003cli\u003eCAT50 taper shank for direct mounting to CAT50 spindle machines\u003c\/li\u003e\n  \u003cli\u003e0.0002 inches TIR for high-concentricity tool holding\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant compatible via through-spindle and DIN flange delivery\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003e4-inch projection for workpiece clearance in standard setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50 spindle machining centers that support ER32 collets.

Power down and lock out the spindle before mounting or removing the chuck from the machine. Use a calibrated torque wrench and the appropriate ER32 collet nut spanner to seat the collet nut to the manufacturer specification for the collet size in use. Verify runout with a dial test indicator after tooling is loaded before running the spindle at speed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: ER32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle and DIN Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 775698\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728003006770,"sku":"775698","price":188.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8688de9bdca0511fa93b1014a64f9877.jpg?v=1788685906","url":"https:\/\/voomisupply.com\/products\/accupro-775698-er32-collet-chuck-cat50-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
