It accepts ER32 collets with a capacity range of 0.078 to 0.787 inches, covering a wide variety of drill, end mill, and reamer shank sizes. The chuck features a 2.48-inch projection from gauge line and holds a total indicator runout (TIR) of 0.0002 inches, supporting tight-tolerance work. Balanced to 25,000 RPM, it is suited for high-speed spindle applications. Through-coolant capability routes coolant directly to the cutting edge for improved chip evacuation and tool life. A licensed machinist or CNC setup technician performs the installation.\u003c\/p\u003e\u003cp\u003eThis collet chuck is intended for use in CAT40-spindle vertical and horizontal machining centers where ER32 toolholding is specified. The 2.48-inch projection makes it well-suited for applications requiring moderate reach without sacrificing rigidity. The through-coolant design supports high-speed drilling, reaming, and milling operations where direct coolant delivery is required. The 50.00 mm nose diameter and 1.97-inch collet nut diameter are standard ER32 dimensions, allowing use with any ER32-series collet from any compatible supplier.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 collet system accepts shank diameters from 0.078 to 0.787 inches\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for direct mounting in CAT40 machining center spindles\u003c\/li\u003e\n\u003cli\u003e2.48-inch projection from gauge line for moderate reach applications\u003c\/li\u003e\n\u003cli\u003e0.0002-inch TIR for precision, tight-tolerance machining\u003c\/li\u003e\n\u003cli\u003eBalanced to 25,000 RPM supporting high-speed spindle operation\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design delivers coolant directly to the cutting zone\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CAT40-taper machining center spindles with ER32-series collets.

The spindle must be fully powered down and the machine placed in a safe lockout state before mounting or removing the chuck. Use the appropriate CAT40 pull-stud and torque the collet nut with a proper ER32 spanner wrench  -  do not use improvised tools that could damage the collet nut or chuck bore. Verify TIR with a dial test indicator after seating the collet and workpiece shank before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\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\u003eProjection\u003c\/strong\u003e: 2.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 25,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 25,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Nut Diameter\u003c\/strong\u003e: 50.00 mm (1.97 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.65 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARLEC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C40-32ERP248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52115123437874,"sku":"C40-32ERP248","price":296.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/117d4c90e71f3a5fa5798986e3a3fbbc.jpg?v=1790079574","url":"https:\/\/voomisupply.com\/products\/parlec-c40-32erp248-er32-collet-chuck-cat40-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
