It handles tap sizes from M3 to M12 (up to 9\/16 inch) and features a 3.445-inch projection from spindle face to nose, making it suitable for reaching into recessed features or deep-set bosses. Built for rigid tapping cycles, this chuck transfers torque and axial motion directly to the tap without a floating or tension-compression mechanism. Through-coolant capability delivers cutting fluid directly to the tap, extending tool life and improving chip evacuation in ferrous and non-ferrous materials. Machinists and CNC setup technicians install this chuck as part of a production tapping solution where synchronization between spindle feed and rotation is maintained by the machine control.\u003c\/p\u003e\u003cp\u003eThis tapping chuck is intended for use on CAT40-spindle vertical and horizontal machining centers performing rigid tapping operations. The Size 1 tap adapter interface accepts a range of collets or adapters to cover the M3 through M12 tap capacity. It fits production environments in job shops, aerospace, automotive, and general manufacturing where repeatable, accurate thread formation is required. The quick-change feature enables fast adapter swaps between tap sizes without removing the body from the spindle, reducing changeover time during multi-tap operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRigid tapping style — direct torque transfer with no axial float for use with synchronized CNC rigid tapping cycles\u003c\/li\u003e\n\u003cli\u003eCAT40 taper shank for secure spindle mounting on standard CAT40 machining centers\u003c\/li\u003e\n\u003cli\u003eM3 to M12 tap capacity (up to 9\/16 inch) covers common production threading range\u003c\/li\u003e\n\u003cli\u003e3.445-inch projection provides reach into recessed workpiece features\u003c\/li\u003e\n\u003cli\u003eThrough-coolant compatible — internal coolant passage delivers fluid to the cutting zone\u003c\/li\u003e\n\u003cli\u003eQuick-change design allows rapid tap adapter swaps at the machine\u003c\/li\u003e\n\u003cli\u003eSize 1 adapter interface with 1.2598-inch nose diameter for consistent toolholder registration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers with a CAT40 spindle taper interface.

Power down or e-stop the machine and verify spindle is fully stopped before inserting or removing the chuck from the spindle. Seat the CAT40 taper fully and torque the retention knob or drawbar to the machining center manufacturer specification before running. When using through-coolant, confirm the machine coolant system and spindle drawbar are configured for through-spindle coolant flow before enabling the feature.\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: M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Capacity (Metric)\u003c\/strong\u003e: M12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Capacity (Inch)\u003c\/strong\u003e: 9\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.445 inches (87.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.2598 inches (32.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Adapter Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 19.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.08 pounds\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-1 CAT-40\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730442125618,"sku":"QCK-1 CAT-40","price":304.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88b58f7a1153d8eea554116fe52c9932.jpg?v=1788717541","url":"https:\/\/voomisupply.com\/products\/accupro-qck-1-cat-40-rigid-tapping-chuck-cat40-m3-m12","provider":"Voomi Supply","version":"1.0","type":"link"}
