It accepts an 18 mm bore diameter and delivers a projection of 102 mm, a nose diameter of 39.6 mm, and a clamping depth of 41 mm. Rated to 15,000 RPM and equipped with through-coolant capability, this chuck is built for high-speed, high-accuracy metal cutting applications. Machinists and tooling technicians install this chuck to achieve consistent radial runout and secure tool grip during milling, drilling, or boring operations.\u003c\/p\u003e\u003cp\u003eThis hydraulic chuck is suited for use in horizontal and vertical CNC machining centers that accept CAT40 spindle interfaces. The through-coolant feature supports directed coolant delivery to the cutting edge, which is critical in deep-pocket milling, long-reach drilling, and heat-sensitive materials. With an overall length of 170.25 mm and a clamping depth of 41 mm, this chuck accommodates a range of cylindrical shank tooling in production and job-shop environments. It is installed by machine tool operators and CNC tooling technicians in both shop-floor and precision manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on standard CAT40 machining centers\u003c\/li\u003e\n\u003cli\u003e18 mm bore diameter with 41 mm clamping depth for secure cylindrical shank grip\u003c\/li\u003e\n\u003cli\u003eHydraulic clamping mechanism provides high gripping force and low runout\u003c\/li\u003e\n\u003cli\u003eRated to 15,000 RPM for high-speed machining applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable for directed coolant flow to the cutting zone\u003c\/li\u003e\n\u003cli\u003e102 mm projection and 39.6 mm nose diameter for accessibility in confined workspaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hydraulic tool chuck for CNC machining centers equipped with a CAT40 spindle taper interface and compatible with cylindrical shank tooling at 18 mm bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC tooling technician or machinist familiar with CAT40 tooling systems. Before mounting or removing the chuck, de-energize the machine and follow all lockout\/tagout procedures per OSHA and facility safety standards. Use the appropriate CAT40 pull stud and torque the retention knob to the machining center manufacturer's specification — do not estimate or exceed the spindle's draw-bar force rating. Inspect the hydraulic chuck for contamination or damage to the bore before each use, as debris can affect clamping force and runout.\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: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 18 mm (0.7087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 39.6 mm (1.5591 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 102 mm (4.031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 41 mm (1.6142 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 170.25 mm (6.7028 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 15,000 RPM\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: 3.3951 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2079282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727254257970,"sku":"2079282","price":950.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ce1a4ab702b6ee0c185731543802b34.jpg?v=1788675475","url":"https:\/\/voomisupply.com\/products\/kennametal-2079282-hydraulic-chuck-cat40-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
