It accepts shell mill cutters with a 1-1\/4 inch pilot diameter and supports cutting diameter ranges from 3 to 3-1\/2 inches. The holder features through-spindle and DIN flange coolant delivery, directing coolant directly to the cutting zone for improved chip evacuation and tool life. A 5\/8-18 lock screw thread secures the shell mill cutter. With a TIR of 0.0002 inches, this holder provides the runout accuracy required for consistent face milling operations. It is installed by machinists and CNC setup technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis holder is suited for face milling applications on ferrous and non-ferrous workpieces in both production and job-shop settings. The CAT40 interface is standard across a wide range of vertical machining centers and horizontal machining centers in North American manufacturing facilities. The through-spindle and DIN flange coolant capability makes it appropriate for applications where flood coolant alone is insufficient, including hard-material face milling and higher-feed operations where chip control is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for compatibility with standard CAT40 spindle interfaces\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch pilot diameter accommodates shell mill cutters in the 3 to 3-1\/2 inch cutting diameter range\u003c\/li\u003e\n\u003cli\u003eThrough-spindle and DIN flange dual coolant delivery directs coolant to the cutting edge\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches supports accurate, low-runout face milling\u003c\/li\u003e\n\u003cli\u003e5\/8-18 lock screw thread for secure cutter retention\u003c\/li\u003e\n\u003cli\u003eProjection from flange to nose end is 2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style shell mill holder for machining centers with CAT40 spindle tapers.

Use the appropriate CAT40 toolholder tightening fixture and torque wrench to seat the draw bar correctly — do not hand-tighten only. Verify TIR at setup with a dial test indicator before beginning a cut. Coolant line connections at the spindle and flange should be inspected for proper seating before enabling coolant flow.\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: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Mill Cutting Diameter Range\u003c\/strong\u003e: 3 to 3-1\/2 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\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle and DIN Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Screw Thread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 775432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728743661874,"sku":"775432","price":156.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b51196bd1138cb2e1074ea1969c85a3f.jpg?v=1788695722","url":"https:\/\/voomisupply.com\/products\/accupro-775432-shell-mill-holder-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
