It accepts a 1-1\/4 inch bore diameter with a bore depth of 101.60 mm (approximately 4.00 inches) and connects to the spindle via a CAT40 taper interface. The body diameter measures 42.80 mm with a body length of 101.60 mm. Internal coolant delivery channels coolant directly to the cutting zone, improving chip evacuation and tool life during deep boring operations. This holder is installed by machining technicians and toolroom specialists working with modular boring systems.\u003c\/p\u003e\u003cp\u003eThis boring bar holder is suited for use on CAT40-equipped vertical and horizontal machining centers in production and job shop environments. The internal coolant feature makes it well suited for ferrous and non-ferrous boring applications where heat and chip buildup are concerns. Lock screw compatibility includes part numbers 5514 022-07, and the coolant screw compatibility is 3214 010-253. The manufacturer part number cross-reference for this holder is AA3B20-40 32 101.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch bore diameter for standard boring bar shank fitment\u003c\/li\u003e\n\u003cli\u003e101.60 mm bore depth for extended reach boring applications\u003c\/li\u003e\n\u003cli\u003eCAT40 taper connection for compatibility with standard machining center spindles\u003c\/li\u003e\n\u003cli\u003eInternal coolant delivery for improved chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003e42.80 mm body diameter with no-head style for clearance in tight bores\u003c\/li\u003e\n\u003cli\u003eLock screw compatibility: 5514 022-07\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible lock screws: 5514 022-07.

Ensure the machine spindle is fully powered down and the tool magazine is in a safe state before mounting or removing the holder. Verify bore diameter and taper seat are clean and free of chips or burrs before seating the holder. Torque all lock screws to the tooling manufacturer specifications using calibrated tooling — do not overtighten.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Depth\u003c\/strong\u003e: 101.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 42.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 101.60 mm (4.00 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Style\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: No Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Screw Size\u003c\/strong\u003e: 4.15 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: 5514 022-07\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Screw Compatibility\u003c\/strong\u003e: 3214 010-253\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.99 inches L x 2.8 inches W x 2.8 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.91 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5721450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744835273010,"sku":"5721450","price":208.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31dd7de17fc1773170c14ea07b5c20cb.jpg?v=1788861235","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721450-boring-bar-holder-cat40","provider":"Voomi Supply","version":"1.0","type":"link"}
