It supports a tap capacity range from M3.5 to M36 (No. 6 to 1-5\/8 inches) for standard taps, and 1\/16 inch to 1-1\/4 inch for pipe taps. The chuck provides up to 0.56 inches of tension float and 0.00 to 0.25 inches of compression float, allowing the chuck to compensate for minor feed-rate discrepancies and protect tap tooling. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone. Projection measures 4.85 inches with a nose diameter of 2.31 inches.\u003c\/p\u003e\n\u003cp\u003eThis tapping chuck is suited for production environments where CNC machining centers perform high-volume tapping across a broad range of thread sizes. It is applicable in aerospace, automotive, and general metalworking operations. The CAT40 modular taper connection provides direct mounting to CAT40 spindles without requiring an intermediate adapter. Through-coolant support makes it well suited for deep-hole tapping or high-temperature materials where chip evacuation and thermal management are critical. It is installed by machinists and CNC setup technicians in shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct spindle connection on compatible machining centers\u003c\/li\u003e\n  \u003cli\u003eWide tap capacity range: M3.5 to M36 (No. 6 to 1-5\/8 inches) for standard taps; 1\/16 inch to 1-1\/4 inch for pipe taps\u003c\/li\u003e\n  \u003cli\u003eTension float of 0.56 inches and compression float of 0.00 to 0.25 inches to protect tap tooling during feed-rate variation\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for pressurized coolant delivery to the cutting zone\u003c\/li\u003e\n  \u003cli\u003e4.85 inch projection with 2.31 inch nose diameter for clearance in confined workpiece features\u003c\/li\u003e\n  \u003cli\u003eNo quick-change mechanism  -  direct collet-style tool holding for a secure, repeatable setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT40 taper spindle machining centers.

Power down and lock out the machining center spindle before mounting or removing the chuck. Ensure the CAT40 taper and spindle bore are clean and free of chips or coolant residue before seating the chuck. Follow the machine tool manufacturer torque specifications for the drawbar when securing the chuck in the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Style\u003c\/strong\u003e: Tension and Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Tap Capacity\u003c\/strong\u003e: M3.5 \/ No. 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Tap Capacity\u003c\/strong\u003e: M36 \/ 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Pipe Tap Capacity\u003c\/strong\u003e: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pipe Tap Capacity\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 4.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTension Float\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompression Float\u003c\/strong\u003e: 0.00 to 0.25 inches\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModular Side Connection Type\u003c\/strong\u003e: Taper\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: PARLEC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C40-77TA4C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52043762565426,"sku":"C40-77TA4C","price":790.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d3f4526ca78ae0d22028fcb0b1ebd8b.jpg?v=1790029346","url":"https:\/\/voomisupply.com\/products\/parlec-c40-77ta4c-tapping-chuck-cat40-tension-compression","provider":"Voomi Supply","version":"1.0","type":"link"}
