It delivers a 3.543-inch projection from spindle face and supports a tap capacity range of M8 to M20 (up to 7\/8 inch), making it suitable for a broad range of threading applications in production environments. The quick-change interface allows fast adapter swaps without removing the chuck body from the spindle, reducing cycle time during multi-tap operations. Through-coolant capability keeps the tap and workpiece cool during deep-hole tapping, extending tool life and improving chip evacuation.\u003c\/p\u003e\u003cp\u003eThis tapping chuck is intended for use on CNC vertical and horizontal machining centers equipped with CAT40 spindle tooling. It is well-suited for production shops, job shops, and toolrooms running rigid tapping cycles in ferrous and non-ferrous materials. The Size 2 adapter interface is a standard modular connection used across a range of tap holder adapters. Machinists and CNC setup technicians are the primary installers and users of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRigid tapping style for synchronized spindle tapping without a floating mechanism\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for compatibility with standard CAT40 spindle tooling systems\u003c\/li\u003e\n\u003cli\u003eQuick-change design allows rapid tap adapter swaps at the machine\u003c\/li\u003e\n\u003cli\u003eThrough-coolant support for improved chip evacuation and tool life in deep-hole tapping\u003c\/li\u003e\n\u003cli\u003eM8 to M20 tap capacity (up to 7\/8 inch) covers a wide range of threading tasks\u003c\/li\u003e\n\u003cli\u003eSize 2 modular adapter interface for broad tap holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT40 spindle tooling systems. Accepts Size 2 tap adapters. Tap capacity ranges from M8 to M20 (7\/8 inch maximum). Specific machine and adapter compatibility should be verified against the machine spindle specification and the adapter manufacturer's sizing chart.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom technician familiar with CAT40 tooling assembly procedures. Power down and lock out the machining center before mounting or removing the chuck from the spindle. Use a torque-rated pull stud and ensure the taper interface is clean and free of chips or burrs before seating. Verify through-coolant port alignment with the machine spindle coolant supply before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Style\u003c\/strong\u003e: Rigid\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: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Tap Capacity\u003c\/strong\u003e: M8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Capacity\u003c\/strong\u003e: M20 (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.543 inches (90.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Adapter Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 31.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change\u003c\/strong\u003e: Yes\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: 3.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: QCK-2 CAT-40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729588683058,"sku":"QCK-2 CAT-40","price":356.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/249f951bc64a5465742dad74d26225ee.jpg?v=1788706461","url":"https:\/\/voomisupply.com\/products\/accupro-qck-2-cat-40-tapping-chuck-cat40-m8-to-m20","provider":"Voomi Supply","version":"1.0","type":"link"}
