The chuck accepts ER32 collets with a capacity range from 1\/16 inch up to 0.788 inches, accommodating a wide variety of cutting tool shanks. With a 4-inch projection and an overall length of 6.687 inches, this chuck positions the cutting tool at a fixed gauge length suited to general-purpose milling, drilling, and reaming operations. It weighs 3.4 pounds and does not include through-coolant capability.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is used in machine shops running CNC vertical or horizontal machining centers equipped with CAT40 spindle interfaces. It is a common choice for production environments where operators need consistent tool projection and repeatable runout performance across multiple tool changes. The ER32 collet system supports a broad range of shank diameters, making this chuck versatile for mixed-tooling setups in both job-shop and production-floor applications. Installation and tool changes are typically performed by machinists or CNC setup technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in CAT40-spindle machining centers\u003c\/li\u003e\n  \u003cli\u003eER32 collet system supports tool shanks from 1\/16 inch to 0.788 inches\u003c\/li\u003e\n  \u003cli\u003e4-inch projection with 6.687-inch overall length for consistent gauge-length setup\u003c\/li\u003e\n  \u003cli\u003eNut tightening torque rated at 100 ft-lb for secure collet clamping\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant port  -  suited for external or flood coolant delivery setups\u003c\/li\u003e\n  \u003cli\u003e3.4-pound chuck weight compatible with standard CAT40 tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT40-spindle CNC machining centers and compatible with the ER32 collet series.

Power down and lock out the machining center spindle before inserting or removing any tool holder. Use a calibrated torque wrench to tighten the ER32 collet nut to the specified 100 ft-lb value  -  under- or over-torquing the nut can affect runout and collet life. Inspect the CAT40 taper and spindle bore for chips or contamination before seating the chuck.\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\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.788 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1\/16 inch\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\u003eProjection\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Tightening Torque\u003c\/strong\u003e: 100 ft-lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.4 pounds\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: TECHNIKS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CAT40ER32-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52085906768178,"sku":"CAT40ER32-4","price":180.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7de28b04e42a6f12d21b7fb1579aafa_66969088-0151-483e-aa2b-b4bb19e6a7bb.jpg?v=1790059291","url":"https:\/\/voomisupply.com\/products\/techniks-cat40er32-4-er32-collet-chuck-cat40-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
