It accepts shell mills through a 0.75 inch pilot diameter and provides a 1.5 inch projection from flange to nose end. The nose diameter measures 1.75 inches. With a TIR of 0.0002 inches and a balance rating of 30,000 RPM, this holder is built for stable, high-speed face milling operations. A 3\/8-24 lock screw thread secures the shell mill to the holder. Licensed machinists and CNC setup technicians working in job shops, tool rooms, and production environments will install and operate this toolholder.\u003c\/p\u003e\u003cp\u003eThe C40-75SM2 is suited for face milling applications in vertical and horizontal machining centers that accept CAT40 tooling. It is appropriate for cutting diameters ranging from 1.75 to 2 inches. The holder does not include through-coolant capability, making it best suited for flood or external coolant delivery setups. Its high RPM balance rating supports both roughing and finishing passes in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting in CAT40 machining centers\u003c\/li\u003e\n\u003cli\u003e0.75 inch pilot diameter with 1.75 inch nose diameter for shell mill fitment\u003c\/li\u003e\n\u003cli\u003e1.5 inch flange-to-nose projection for standard reach applications\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches for precise, low-runout performance\u003c\/li\u003e\n\u003cli\u003eBalanced to 30,000 RPM for high-speed machining compatibility\u003c\/li\u003e\n\u003cli\u003e3\/8-24 lock screw thread with included lock screw 75LS\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with shell mills in the 1.75 to 2 inch cutting diameter range.

Power down and lock out the machining center spindle before mounting or removing the holder. Use a CAT40-rated toolholder tightening fixture and the appropriate pull stud for the target spindle when assembling. Verify runout with a dial indicator after mounting to confirm TIR is within acceptable limits for the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Mill Cutting Diameter Range\u003c\/strong\u003e: 1.75 to 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Screw Thread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Screw\u003c\/strong\u003e: 75LS\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\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 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: C40-75SM2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":51971483140402,"sku":"C40-75SM2","price":215.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5f65ac47b8db58114b2a8d3a260e504.jpg?v=1789957785","url":"https:\/\/voomisupply.com\/products\/parlec-c40-75sm2-shell-mill-holder-cat40-0-75-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
