It accepts shell mill cutters with a 1.0000 inch pilot diameter and a 2.2500 inch nose diameter, with a projection from flange to nose end of 2.0000 inches. Through-spindle coolant delivery is supported, making it suitable for high-efficiency cutting applications where chip evacuation and tool-life management are priorities. Balanced to 30,000 RPM, this holder suits both standard and high-speed spindle configurations. A licensed machinist or tooling specialist installs and qualifies this holder as part of a precision tooling setup.\u003c\/p\u003e\n\u003cp\u003eThe B40-10SM2 is used in vertical and horizontal CNC machining centers equipped with BT40 spindle interfaces. It is suited for face milling, shoulder milling, and surface milling operations in production and job-shop environments. Shell mill cutter diameters ranging from 2.25 inches to 2.75 inches are compatible with this holder. Through-spindle coolant requires the separate Parlec 10LSC or 028-188C coolant-through adapter; the holder does not function as a standalone coolant-through assembly without one of those components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBT40 taper shank for direct mounting in BT40-interface machining center spindles\u003c\/li\u003e\n  \u003cli\u003e1.0000 inch pilot diameter with 2.2500 inch nose diameter for secure shell mill seating\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle coolant capability via compatible Parlec 10LSC or 028-188C adapter\u003c\/li\u003e\n  \u003cli\u003eTIR of 0.0002 inches for precision runout control during face milling\u003c\/li\u003e\n  \u003cli\u003eBalanced to 30,000 RPM for high-speed spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eLock screw thread size of 1\/2-20 for cutter retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with a BT40 spindle taper interface. Accepts shell mill cutters in the 2.25 inch to 2.75 inch cutting diameter range.

The spindle must be fully powered down and at a complete stop before mounting or removing the holder. Use a proper BT40 retention knob and torque the drawbar to the machining center manufacturer's specified value. Verify runout with a dial test indicator after seating the holder before initiating any cutting pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003ePilot Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShell Mill Cutting Diameter Range\u003c\/strong\u003e: 2.25 inches to 2.75 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\u003eLock Screw Thread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBalanced To RPM\u003c\/strong\u003e: 30,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 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: B40-10SM2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52018392596786,"sku":"B40-10SM2","price":206.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77309c6a99b7bfeac9d7f4669ed90030.jpg?v=1790010116","url":"https:\/\/voomisupply.com\/products\/parlec-b40-10sm2-shell-mill-holder-bt40-1-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
