It features a CAT40 taper shank connection and accepts tooling with a 1\/2 inch bore diameter. The hydraulic clamping mechanism delivers consistent radial runout performance with a TIR of 0.000010 inches, making it well suited for finishing passes and tight-tolerance work. Through-coolant capability supports extended tool life when machining ferrous and non-ferrous materials. Licensed machinists and CNC setup technicians are the primary installers of this holder in production shop environments.\u003c\/p\u003e\n\u003cp\u003eThis holder is intended for use in CAT40-spindle vertical and horizontal machining centers performing milling, drilling, and reaming operations that demand high rotational accuracy. With a balanced speed rating of 25,000 RPM, it is suitable for high-speed machining applications in both job shop and production settings. The clamping depth of 46.00 mm provides secure tool engagement, and the 64.00 mm projection suits standard reach requirements without excessive overhang. This part replaces the previously catalogued SKU 56509599.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct mounting in standard CAT40 spindles\u003c\/li\u003e\n  \u003cli\u003eHydraulic clamping mechanism achieves TIR of 0.000010 inches for high-precision runout control\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant compatible for improved chip evacuation and tool life\u003c\/li\u003e\n  \u003cli\u003eBalanced to 25,000 RPM for high-speed machining center use\u003c\/li\u003e\n  \u003cli\u003e46.00 mm clamping depth ensures positive tool retention under cutting loads\u003c\/li\u003e\n  \u003cli\u003eReplaces SKU 56509599 for direct service interchange\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CAT40-spindle machining centers.

Ensure the spindle is fully de-energized and the machine is in a safe lockout state before changing toolholders. Clean the CAT40 taper and spindle bore thoroughly before seating the holder to prevent seating errors that affect runout. Hydraulic holders require a dedicated hydraulic chuck key for actuation and should not be over-pressurized beyond the manufacturer's specified clamping range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: CAT40\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 27.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 64.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 46.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1.9291 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.000010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 25,000 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: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1527332\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743311135026,"sku":"1527332","price":367.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f65d14fa88f13e1f7bbcefbc2d0e585.jpg?v=1788845463","url":"https:\/\/voomisupply.com\/products\/accupro-1527332-hydraulic-chuck-cat40-1-2-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
