With a 4-inch blank diameter and an overall length of 11 inches, this holder provides the raw form needed for custom boring, turning, or specialty tooling setups. The CAT50 taper shank delivers positive engagement with the machine spindle, making it suited for heavy-duty milling and machining center applications. At 22 pounds, this is a substantial blank intended for shops that machine their own tooling or require non-standard configurations. Machinists and toolroom specialists are the primary end users.\u003c\/p\u003e\n\u003cp\u003eThis blank is used in horizontal and vertical machining centers equipped with CAT50 spindle tapers. It is well suited to production environments where standard off-the-shelf holders do not meet specific reach, diameter, or bore requirements. The 6.25-inch projection from flange to nose end and the 7-inch projection from gage line to nose end provide extended clearance for deep-cavity or large-diameter workpiece applications. Machine shops, toolrooms, and job shops performing custom tooling fabrication will find this blank applicable to a wide range of setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for secure spindle engagement on compatible machining centers\u003c\/li\u003e\n  \u003cli\u003e4-inch blank diameter provides ample stock for custom boring and machining\u003c\/li\u003e\n  \u003cli\u003e11-inch overall length suits deep-reach and extended-projection applications\u003c\/li\u003e\n  \u003cli\u003e6.25-inch flange-to-nose projection for clearance in large or deep workpiece setups\u003c\/li\u003e\n  \u003cli\u003e7-inch gage-line-to-nose projection for precise reach planning\u003c\/li\u003e\n  \u003cli\u003eSubstantial 22-pound construction indicates solid, high-mass blank stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50 spindle taper machining centers as an unfinished blank requiring secondary machining to final toolholder configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and finishing of this blank should be performed by qualified machinists familiar with CAT taper toolholder standards. Ensure the machine spindle is powered down and locked out before any holder installation or removal. Proper draw bar engagement and spindle taper cleanliness are critical for safe and accurate operation. Follow the machining center manufacturer guidelines for pull stud specifications and drawbar torque when mounting any CAT50 holder.\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: CAT50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlank Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection Gage Line to Nose End\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22 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: C50-40BB7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARLEC","offers":[{"title":"Default Title","offer_id":52083956351282,"sku":"C50-40BB7","price":369.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e3be3ceef674edc5220c1ffbbd4b2e4.jpg?v=1790057905","url":"https:\/\/voomisupply.com\/products\/parlec-c50-40bb7-rotary-tool-holder-blank-cat50-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
