It accepts ER20-series collets with a clamping range of 1 mm to 13 mm (0.0394 inches to 0.5118 inches), covering a broad range of small-diameter cutting tools and drill shanks. The chuck features a straight shank measuring 22 mm (0.8661 inches) in diameter and an overall length of 119 mm (4.6850 inches), with a projection of 39 mm (1.5354 inches). Through-spindle coolant capability delivers cutting fluid directly to the tool tip for improved chip evacuation and tool life. This chuck is installed by machinists and CNC setup technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis collet chuck is suited for use in vertical and horizontal machining centers, CNC milling machines, and drilling stations where ER20 tooling is the standard interface. The straight shank configuration is compatible with straight-bore spindles and tool holders. Through-coolant capability makes it well suited for deep-hole drilling, high-speed milling, and applications where heat management is critical. The 22 mm shank diameter and compact nose diameter of 28 mm (1.1024 inches) allow access in tighter workpiece geometries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet system with 1 mm to 13 mm clamping capacity\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant support for direct tool-tip fluid delivery\u003c\/li\u003e\n  \u003cli\u003eStraight shank design at 22 mm (0.8661 inches) diameter\u003c\/li\u003e\n  \u003cli\u003e119 mm (4.6850 inches) overall length with 39 mm (1.5354 inches) projection\u003c\/li\u003e\n  \u003cli\u003eNose diameter of 28 mm (1.1024 inches) for access in confined setups\u003c\/li\u003e\n  \u003cli\u003eAccepts standard ER20-series collets for broad tooling compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER20-series collets in straight-bore spindle interfaces on CNC machining centers and milling machines requiring a 22 mm straight shank tool holder with through-coolant capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Power down and de-energize the machine spindle before mounting or removing the chuck. Ensure the spindle bore and shank surfaces are clean and free of chips or burrs before seating the chuck. Verify coolant line connections are secure and check for leaks before returning the machine to full operation.\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\u003eMinimum Collet Capacity\u003c\/strong\u003e: 1 mm (0.0394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 13 mm (0.5118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 22 mm (0.8661 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 119 mm (4.6850 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 39 mm (1.5354 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 28 mm (1.1024 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4501993\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":67950281425202,"sku":"4501993","price":257.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/103e39d0c70e2c5479457d17ddc55131_2534ed0d-d2b8-4b59-86ce-698c8c6286e5.jpg?v=1791712099","url":"https:\/\/voomisupply.com\/products\/iscar-4501993-er20-collet-chuck-22mm-straight-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
