Part of the T-Max P series, this steel-bodied bar uses a wedge-style insert clamping system to secure DNMG 11 04 08 inserts with a negative rake geometry. The right-hand configuration, combined with a -3 degree lead angle and -6 degree rake angle, positions the cutting edge for reliable chip control on a wide range of bore profiles. Coolant-through capability allows cutting fluid delivery directly to the insert tip, supporting tool life and chip evacuation in deep-bore applications. Machinists and CNC programmers specify this bar for precision internal diameter work where insert repeatability and rigidity are critical.\u003c\/p\u003e\u003cp\u003eThis boring bar suits residential and commercial machine shop environments, job shops, and production facilities running internal turning on steel, cast iron, and similar workpiece materials. It is intended for use in 3\/4 inch diameter shank toolholders on CNC lathes, turning centers, or manual lathes with sufficient spindle bore clearance. The 1.2008 inch minimum bore diameter and 10 inch overall length make it appropriate for moderately deep bore applications where reach and clearance are primary setup considerations. The multi-use designation confirms suitability across varied internal turning scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWedge-style insert clamping secures DNMG 11 04 08 inserts for repeatable edge positioning\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone for improved chip evacuation and insert life\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry (-6 degrees rake, -3 degrees lead angle) supports stable cutting on ferrous and hard workpiece materials\u003c\/li\u003e\n\u003cli\u003eSteel toolholder body provides rigidity and dampening in standard boring applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration compatible with standard CNC lathe turret setups\u003c\/li\u003e\n\u003cli\u003eT-Max P series construction supports consistent insert indexing and clamping force\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DNMG 11 04 08 inserts.

Power down and lock out the machine spindle before mounting or removing the toolholder from the turret. Ensure the shank is fully seated and clamped to the tool block manufacturer's specified engagement depth. Inspect the insert seat and wedge clamp for chips or damage before indexing or replacing inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.2008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -6 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DNMG 11 04 08\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.16 inches L x 1.4 inches W x 1.4 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 5721706\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752490697010,"sku":"5721706","price":520.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4913ad47695a78c9762ac74cd29dbc7e_75cdb80a-e4f0-453e-b8ff-8f9d815b55ae.jpg?v=1788928553","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721706-indexable-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
