The chuck features an 8-inch projection from gauge line, providing extended reach for deep-cavity work without sacrificing rigidity. It accepts ER20 collets across a clamping range of 1\/16 inch to 1\/2 inch, making it compatible with a wide variety of cutting tool shank diameters. Overall length is 12 inches. Weighing 9 pounds, the 22295 is built for production environments where tool runout and repeatability are critical.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is suited for vertical and horizontal machining centers equipped with CAT50 spindle interfaces. The extended 8-inch projection makes it appropriate for workpieces that require tooling clearance beyond what a standard-length chuck can provide, such as deep mold cavities, fixture plates with tall risers, or multi-axis setups where reach is constrained by the workholding arrangement. It is installed and changed out by CNC machinists and toolroom technicians in job shop, production, and die-mold environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for direct mounting in CAT50-interface spindles\u003c\/li\u003e\n  \u003cli\u003eER20 collet system accepts shanks from 1\/16 inch to 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e8-inch projection for extended reach into deep-cavity workpieces\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length for clearance in tall-workpiece setups\u003c\/li\u003e\n  \u003cli\u003eNo through-coolant  -  suitable for flood or mist coolant delivery from the outside\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50 spindle-interface machining centers and standard ER20 collets.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout-tagout state before changing toolholders. Clean the taper shank and spindle bore thoroughly before seating to prevent runout caused by chips or contamination. Torque the collet nut to the collet manufacturer's specification using a calibrated wrench.\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: ER20\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: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 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\u003eMaximum Collet Capacity\u003c\/strong\u003e: 1\/2 inch\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: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112808\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: 22295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":51973281972530,"sku":"22295","price":343.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a72a1322d261b82fd7459a3f4256b54.jpg?v=1789972715","url":"https:\/\/voomisupply.com\/products\/techniks-22295-er20-collet-chuck-cat50-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
