It features an ER32 taper shank and a 0.2362-inch hole diameter, making it suitable for securing cutting tools with consistent radial accuracy. With a projection of 2.3622 inches and a nose diameter of 0.4331 inches, this adapter is built for setups where tool reach and rigidity are critical. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, supporting higher speeds and longer tool life in demanding operations. Machinists and tool crib technicians working in production or job-shop environments will find this adapter a reliable component in shrink-fit tooling systems.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for use in vertical and horizontal machining centers equipped with shrink-fit toolholding systems. The ER32 taper shank interfaces with compatible shrink-fit chucks and spindle configurations commonly found in precision metalworking environments. A clamping depth of 0.9449 inches provides secure tool engagement for milling, drilling, and boring operations across a range of materials. It is a direct fit for operations requiring through-coolant delivery at the spindle interface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eER32 taper shank for compatibility with standard shrink-fit toolholding systems\u003c\/li\u003e\n\u003cli\u003e0.2362-inch hole diameter for precise tool insertion and runout control\u003c\/li\u003e\n\u003cli\u003e2.3622-inch projection for extended reach in deep-cavity or confined-workpiece applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design delivers cutting fluid directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003e0.9449-inch clamping depth ensures secure and stable tool retention\u003c\/li\u003e\n\u003cli\u003e0.4331-inch nose diameter for clearance in tight-tolerance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style shrink-fit tool holder adapter for machining centers equipped with ER32 taper shank shrink-fit toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with shrink-fit toolholding procedures. Spindle power must be fully off and the machine in a safe, locked-out state before any toolholder change. Use an appropriate induction shrink-fit heater to expand the holder bore before inserting or removing the cutting tool — never force tools in or out without heating. Verify through-coolant port alignment and sealing per the machine tool manufacturer specifications before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: ER32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.3622 inches (60.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.4331 inches (11.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 0.9449 inches (24.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.467 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4509109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727514566962,"sku":"4509109","price":175.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a54af9ebd54399711a3a7e4905273e03.jpg?v=1788678761","url":"https:\/\/voomisupply.com\/products\/iscar-4509109-shrink-fit-tool-holder-adapter-er32","provider":"Voomi Supply","version":"1.0","type":"link"}
