This left-hand cutting head features a Size C4 system with a head connection size of C5, a head length projection of 70 mm (2.7559 inches), and a minimum hole diameter of 20 mm (0.7874 inches). It accepts CCMT 09T308 inserts held by a clamp and screw method, and includes through-coolant capability to support high-performance machining in deep-bore applications. The neck diameter is 40 mm (1.5748 inches), and the center-to-cutting-edge distance is 11 mm (0.4331 inches).\u003c\/p\u003e\n\u003cp\u003eThis profiling head is suited for internal finish and semi-finish turning in bore depths up to 70 mm (2.7559 inches). It is used in production and job-shop environments where modular tooling systems are employed for quick changeover and repeatable tool positioning. The left-hand cutting direction makes it appropriate for specific spindle rotation and bore-entry configurations on both horizontal and vertical turning machines. Machinists and CNC tooling technicians working in aerospace, automotive, and general precision machining will encounter this head in modular boring bar assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoroTurn 107 series modular system with Size C4 body and C5 head connection\u003c\/li\u003e\n  \u003cli\u003eLeft-hand internal cutting direction for bore profiling and turning\u003c\/li\u003e\n  \u003cli\u003eAccepts CCMT 09T308 inserts via clamp and screw holding method\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant enabled for chip evacuation and tool life in deep-bore cuts\u003c\/li\u003e\n  \u003cli\u003eHead length projection of 70 mm (2.7559 inches) with minimum hole diameter of 20 mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003eRadial rake angle of -8.3967 degrees and axial rake angle of 0 degrees for controlled chip formation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with CCMT 09T308 inserts.

Ensure the modular connection interface is clean and free of debris before seating the head to maintain accurate tool positioning. Torque the clamping mechanism according to the tooling system documentation for the C5 connection interface. Verify coolant passage alignment before engaging through-coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Size\u003c\/strong\u003e: C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Connection Size\u003c\/strong\u003e: C5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal or External\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: CCMT 09T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length Projection\u003c\/strong\u003e: 70 mm (2.7559 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 20 mm (0.7874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 70 mm (2.7559 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 40 mm (1.5748 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 11 mm (0.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAxial Rake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadial Rake Angle\u003c\/strong\u003e: -8.3967 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Dimensions (L x W x H)\u003c\/strong\u003e: 4.33 inches x 1.97 inches x 1.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5727878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755354390834,"sku":"5727878","price":657.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fda7b07277ed1734b1f4ffddc53849f.jpg?v=1788954066","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5727878-modular-turning-profiling-head-c4","provider":"Voomi Supply","version":"1.0","type":"link"}
