It provides a 3-inch projection from the spindle face and holds a total indicator reading (TIR) of 0.0002 inches, making it suitable for precision machining applications where runout directly affects tool life and surface finish. The chuck features through-spindle coolant delivery, allowing coolant to reach the cutting zone without external nozzles. It accepts collets ranging from 3\/64 inch to 3\/4 inch capacity and has a nose diameter of 2.1 inches. Machinists and CNC setup technicians are the primary installers of this toolholder.\u003c\/p\u003e\u003cp\u003eThis collet chuck is used in CNC machining centers equipped with CAT50 spindles, common in medium-to-heavy-duty production environments including job shops, aerospace, and general manufacturing. The 3-inch projection suits applications where reach past fixtures or part features is required. Through-coolant capability supports drilling, reaming, and milling operations where flood coolant alone is insufficient to clear chips or cool the cutting edge effectively. The TG and PG75 collet system is widely used where high clamping force and vibration damping are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 taper shank for compatibility with standard V-flange spindles\u003c\/li\u003e\n\u003cli\u003eTG and PG75 single angle collet system with 3\/64 inch to 3\/4 inch capacity range\u003c\/li\u003e\n\u003cli\u003e3-inch projection from spindle face for extended reach applications\u003c\/li\u003e\n\u003cli\u003e0.0002 inch TIR for precision runout control\u003c\/li\u003e\n\u003cli\u003eThrough-spindle coolant delivery for chip evacuation and tool cooling at the cutting zone\u003c\/li\u003e\n\u003cli\u003e2.1-inch nose diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with TG series and PG75 series single angle collets.

The spindle must be fully stopped and the machine in a safe, locked-out state before mounting or removing any toolholder. Ensure the taper and spindle bore are clean and free of chips or oil film before seating the chuck. Torque the retention knob or drawbar to the machine builder specification, not a generic value, as CAT50 retention requirements vary by spindle model.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: Single Angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: TG, PG75\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: CAT50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 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: PARLEC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C50BC-75SC300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51972468310322,"sku":"C50BC-75SC300","price":232.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7aab30b4480305bd494e7faff91e9e39_4a5fac1e-85f2-40d3-bfa6-984d4a49aabb.jpg?v=1789969480","url":"https:\/\/voomisupply.com\/products\/parlec-c50bc-75sc300-collet-chuck-cat50-tg-pg75","provider":"Voomi Supply","version":"1.0","type":"link"}
