It accepts DA180-series collets with a capacity range of 0.0313 to 0.75 inches, covering a wide range of cutting tool shank sizes. The chuck mounts on a BT40 taper shank and delivers a total indicator reading (TIR) of 0.0004 inches, making it suitable for high-accuracy milling, drilling, and reaming operations. Through-spindle coolant is supported, directing coolant directly to the cutting zone. With a 3-inch projection and an overall length of 5.575 inches, this chuck is installed and serviced by CNC machine operators and toolroom machinists.\u003c\/p\u003e\n\u003cp\u003eThe B40-18DC3 is intended for use in BT40-spindle machining centers running DA180-series collets. The 3-inch projection provides clearance for workpiece features that require tool reach beyond the spindle face. Through-coolant capability suits materials and operations where chip evacuation and cutting-edge cooling are critical, such as deep-hole drilling or high-speed milling. This chuck is a standard toolholder choice for production and job-shop environments using BT40-compatible machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDA180 double angle collet system with 0.0313 to 0.75 inches clamping range\u003c\/li\u003e\n  \u003cli\u003eBT40 taper shank for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n  \u003cli\u003e0.0004 inches TIR for high-precision tool holding\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant delivery for improved chip evacuation and tool life\u003c\/li\u003e\n  \u003cli\u003e3-inch projection with 5.575 inches overall length for reach into deep features\u003c\/li\u003e\n  \u003cli\u003e1.44 inches nose diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for BT40-spindle machining centers using DA180-series double angle collets with shank diameters from 0.0313 to 0.75 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the toolholder. Use the correct BT40 pull stud and verify it is properly torqued per the machine tool manufacturer specification before use. Inspect the collet and chuck bore for chips or damage before assembly, as contamination directly affects TIR and tool life.\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: DA180\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: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Collet Capacity\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\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: 1.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\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: B40-18DC3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52042136289586,"sku":"B40-18DC3","price":200.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6f38fd73264453e09aab75ff1cd6903.jpg?v=1790028156","url":"https:\/\/voomisupply.com\/products\/parlec-b40-18dc3-collet-chuck-bt40-da180-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
