Constructed from solid carbide, the bar provides rigidity and vibration resistance at small bore diameters. It accepts CP-style inserts secured by a screw-clamp holding method and features through-coolant capability via a 0.125-inch coolant hole, supporting chip evacuation and tool life at the cutting edge. With a minimum bore diameter of 0.48 inches and a maximum bore depth of 2.25 inches, it is suited for tight-tolerance bores in production and job-shop environments. The toolholder follows the E06SCLPL2 style designation within the Series E line.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use on CNC lathes and turning centers where left-hand cutting orientation is required. It is well suited to finish boring operations on steel, cast iron, and similar workpiece materials in both high-volume production and low-volume precision work. The through-coolant feature makes it particularly appropriate for deeper bores where flood coolant alone is insufficient to clear chips from the cutting zone. Machinists and tooling specialists working in precision turning applications will find this bar compatible with standard E-series boring head setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and vibration damping in small-bore applications\u003c\/li\u003e\n\u003cli\u003eLeft-hand cut orientation — E06SCLPL2 toolholder style\u003c\/li\u003e\n\u003cli\u003eThrough-coolant delivery via 0.125-inch coolant hole for chip evacuation and thermal control\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eAccepts CP-style inserts for broad insert selection flexibility\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter using diamond insert cartridge: 0.25 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CP.. series inserts as specified by the E06SCLPL2 toolholder style designation.

Ensure the machine spindle is fully stopped and all energy is locked out before mounting or removing the boring bar. Verify shank clamping torque per the machine tool manufacturer's boring head specifications — do not exceed rated clamp force. Confirm coolant line connection and pressure compatibility before enabling through-coolant flow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.48 inches (12.19 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter with Diamond Insert Cartridge\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 2.25 inches (57.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.25 inches\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\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: E06SCLPL2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CP..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.112 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51745697661234,"sku":"7000504","price":1756.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44e298776be2dbfc969c6016ee0834af.jpg?v=1788864801","url":"https:\/\/voomisupply.com\/products\/hertel-7000504-indexable-boring-bar-left-hand-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
