Built with a CAT50 taper connection and a Size 3 adapter, this chuck accepts taps ranging from 13\/16 inch minimum up to 1-3\/8 inch maximum capacity. The 5.11-inch projection provides the clearance needed for deeper bores and fixture-heavy setups. Quick-change functionality is included, reducing tool changeover time on the floor. Weighing 1 pound, it is straightforward to handle during setup. Licensed machinists and CNC operators are the primary users of this toolholder.\u003c\/p\u003e\n\u003cp\u003eThis tapping chuck is suited for rigid tapping cycles on vertical and horizontal machining centers equipped with a CAT50 spindle interface. It supports pipe tap applications starting at 13\/16 inch minimum capacity. Typical install scenarios include production shops running high-volume threading operations where through-coolant is not required. The quick-change design makes it practical for shops that rotate multiple tap sizes on a single setup without full toolholder swaps.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for secure spindle engagement on compatible machining centers\u003c\/li\u003e\n  \u003cli\u003eRigid tapping style for synchronous tapping cycles requiring no floating compensation\u003c\/li\u003e\n  \u003cli\u003eTap capacity range from 13\/16 inch to 1-3\/8 inch, covering a broad range of thread sizes\u003c\/li\u003e\n  \u003cli\u003e5.11-inch projection for clearance in deep-bore and complex-fixture applications\u003c\/li\u003e\n  \u003cli\u003eQuick-change interface reduces tap swap time during production runs\u003c\/li\u003e\n  \u003cli\u003eSize 3 adapter for compatibility with corresponding tap holders and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50 spindle machines requiring a rigid tapping chuck with a Size 3 tap adapter.

Ensure the spindle is fully powered down and the machine is placed in a safe state before mounting or removing the toolholder. Follow the machine manufacturer's draw bar torque and retention knob specifications for CAT50 toolholders. Verify tap adapter seating and confirm rigid tapping parameters in the CNC control before running the first cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Tap Capacity\u003c\/strong\u003e: 13\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Tap Capacity\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 5.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Adapter Size\u003c\/strong\u003e: 3\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Pipe Tap Capacity\u003c\/strong\u003e: 13\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 778594\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739127841074,"sku":"778594","price":396.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f9ba0c659fc02a7354af1c923c7eb1d.jpg?v=1788809912","url":"https:\/\/voomisupply.com\/products\/accupro-778594-rigid-tapping-chuck-cat50-1-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
