Built to the L-MNE toolholder style with a 3\/8-inch shank diameter, it accepts N.1L inserts secured by a clamp-style holding method. The bar has an overall length of 6 inches and a minimum bore diameter of 0.48 inches, making it suitable for small-diameter finish boring work. The heavy metal construction increases mass and dampens vibration in deep or interrupted bore applications. Coolant-through capability is supported via a 0.1250-inch coolant hole diameter, helping clear chips and extend insert life at the cutting edge.\u003c\/p\u003e\n\u003cp\u003eThis boring bar fits standard lathe toolposts and turret stations that accept 3\/8-inch round shank toolholders. It is used in production and job-shop environments for right-hand internal boring passes on ferrous and non-ferrous workpieces. The Top Notch series designation indicates compatibility with the corresponding insert and seating system. Machinists and CNC setup technicians working on tight-tolerance bore diameters starting at 0.48 inches will find this bar appropriate for both roughing and semi-finish passes depending on insert selection. It is not a multi-use tool and is intended strictly for single-point boring operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMinimum bore diameter of 0.48 inches supports small-bore internal turning work\u003c\/li\u003e\n  \u003cli\u003eHeavy metal shank construction reduces vibration and chatter in deep bores\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding secures N.1L inserts for repeatable edge positioning\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with 0.1250-inch coolant hole improves chip evacuation and insert life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard lathe rotation\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides reach for typical production boring depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with N.1L series inserts using the Top Notch insert system.

Secure the shank fully in the toolholder bore and confirm the cutting edge is on center before taking a pass. Power down and lock out the machine spindle before changing inserts or adjusting the bar position. Do not exceed the minimum bore diameter rating, as doing so risks insert and workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.265 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: N.1L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: L-MNE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Heavy Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3331088\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738633699634,"sku":"3331088","price":474.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fdc14303d1bf373712adb55932b831c.jpg?v=1788802129","url":"https:\/\/voomisupply.com\/products\/kennametal-3331088-indexable-boring-bar-0-48-in-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
