Built on a BT40 taper shank, it accepts TG and PG75 series collets and covers a capacity range from 0.031 inches (0.79 mm) up to 0.750 inches. The chuck features through-spindle coolant delivery, directing cutting fluid directly to the tool tip for improved chip evacuation and tool life. Projection measures 2.75 inches with an overall length of 5.325 inches and a total indicator runout (TIR) of 0.0002 inches, making it suitable for tight-tolerance work. This toolholder is used and installed by CNC machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis collet chuck is suited for vertical and horizontal machining centers equipped with BT40 spindles. The TG and PG75 collet system is a widely adopted single angle collet standard, commonly found in production milling, drilling, and light reaming operations. Through-spindle coolant compatibility makes it a practical choice for high-speed operations where flood coolant alone is insufficient. The 2.75-inch projection provides clearance for workpiece features and fixtures in typical setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBT40 taper shank for compatibility with BT40-spindle machining centers\u003c\/li\u003e\n\u003cli\u003eAccepts TG and PG75 series single angle collets\u003c\/li\u003e\n\u003cli\u003eCollet capacity range: 0.031 inches to 0.750 inches\u003c\/li\u003e\n\u003cli\u003eThrough-spindle coolant delivery for direct tool-tip cooling\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches for high-precision runout control\u003c\/li\u003e\n\u003cli\u003e2.75-inch projection with 5.325-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with BT40-spindle CNC machining centers and accepts TG series and PG75 series single angle collets.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified CNC machinist or toolroom technician with the machine in an E-stop or powered-down state and spindle fully stopped. Use the appropriate BT40 pull stud and a calibrated torque wrench per the machine tool manufacturer specifications when securing the retention knob. Verify TIR after seating with a dial test indicator before committing to a production run. Confirm through-coolant fittings and spindle coolant passages are clear and properly sealed before enabling coolant flow.\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 and 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: BT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.031 inches (0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.325 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 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: 3 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: B40-75SC3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51980506530098,"sku":"B40-75SC3","price":203.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73dade7a7884f3a8f185fba3854986c4.jpg?v=1789981604","url":"https:\/\/voomisupply.com\/products\/parlec-b40-75sc3-collet-chuck-bt40-tg-pg75-single-angle","provider":"Voomi Supply","version":"1.0","type":"link"}
