It holds taps up to 9\/16 inch capacity and provides a projection of 2.95 inches from the gauge line. The quick-change design speeds up tap swaps during production runs. This chuck is intended for use on CNC machining centers and tapping machines where consistent thread quality and rigid tap alignment are required. Licensed machinists and CNC operators install and configure this tooling in machine shops and production environments.\u003c\/p\u003e\u003cp\u003eThis chuck suits applications on BT40-spindle CNC machining centers performing rigid tapping cycles. The 9\/16 inch maximum tap capacity covers common inch-size taps used in ferrous and non-ferrous materials. The Size 1 tap adapter interface provides a standardized connection between the chuck body and the tap holder. It is appropriate for both job-shop and high-volume production tapping operations where rigid tapping mode is available on the machine control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRigid tapping style eliminates the need for tension-compression float, supporting synchronous tapping cycles\u003c\/li\u003e\n\u003cli\u003eBT40 taper shank for direct mounting in BT40-spindle machining centers\u003c\/li\u003e\n\u003cli\u003e9\/16 inch maximum tap capacity accommodates a wide range of common inch-size taps\u003c\/li\u003e\n\u003cli\u003e2.95 inch projection provides clearance for most standard workpiece setups\u003c\/li\u003e\n\u003cli\u003eQuick-change design reduces tap changeover time during production runs\u003c\/li\u003e\n\u003cli\u003eSize 1 tap adapter connection for standardized tap holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with BT40-spindle CNC machining centers equipped with rigid tapping capability.

Follow the machine tool manufacturer guidelines for BT40 tooling torque and drawbar retention procedures. Inspect the taper bore and chuck taper for nicks, chips, or contamination before seating the chuck in the spindle. Confirm that the machine control is set to rigid tapping mode before running a tapping cycle with this chuck.\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 Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: BT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tap Capacity\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Tap Capacity\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Adapter Size\u003c\/strong\u003e: 1\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: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 778620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732979810610,"sku":"778620","price":258.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d51b9909c8cc2709d8d6dd7b609b8461.jpg?v=1788749919","url":"https:\/\/voomisupply.com\/products\/accupro-778620-rigid-tapping-chuck-bt40-9-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
