It accepts DA300-series collets with a clamping range of 0.0313 to 0.25 inches, making it suitable for a wide variety of small-diameter end mills, drills, and reamers. The chuck mounts on a BT40 taper shank and delivers a total indicator runout (TIR) of 0.0004 inches, supporting tight-tolerance machining requirements. Through-spindle coolant capability directs cutting fluid directly to the tool tip. This tool holder is installed and serviced by CNC machinists and tool crib technicians in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThe B40-30DC3 is suited for vertical and horizontal machining centers equipped with BT40 spindle interfaces. The 3-inch projection provides clearance for workpiece features and fixturing in typical milling setups. The DA300 collet series is a widely used double angle system, and this chuck is appropriate for operations requiring consistent runout performance and reliable coolant delivery at the cutting zone. It is commonly used in both production runs and prototype machining where tool reach and accuracy are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDA300 double angle collet system with 0.0313 to 0.25 inch clamping range\u003c\/li\u003e\n  \u003cli\u003eBT40 taper shank for compatibility with BT40 spindle machines\u003c\/li\u003e\n  \u003cli\u003e0.0004 inch TIR for high-accuracy, low-runout tool holding\u003c\/li\u003e\n  \u003cli\u003e3 inch projection for workpiece and fixture clearance\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery directs fluid to the cutting edge\u003c\/li\u003e\n  \u003cli\u003e5.575 inch overall length suits standard machining center setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with DA300-series double angle collets on CNC machining centers equipped with a BT40 spindle taper interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle and tool holder tapers are clean and free of chips or coolant residue before seating the chuck. Use the appropriate BT40 pull stud and torque the retention knob per the machine tool manufacturer specification. Inspect collet seating and verify TIR with a dial indicator after installation before beginning any cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet System\u003c\/strong\u003e: Double Angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollet Series\u003c\/strong\u003e: DA300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: BT40 Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Collet Capacity\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0004 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\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: B40-30DC3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52060476375346,"sku":"B40-30DC3","price":199.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14b35e3b625ef100b8ce466cf5fca3ee.jpg?v=1790041109","url":"https:\/\/voomisupply.com\/products\/parlec-b40-30dc3-da300-double-angle-collet-chuck-bt40","provider":"Voomi Supply","version":"1.0","type":"link"}
