Built to the A10SCLPL2 toolholder style in the A-series, it features a 5\/8-inch shank diameter and a 10-inch overall length, making it well suited for reaching into deep bores while maintaining rigidity. The bar is constructed from steel and accepts CP.. 21.51 series inserts secured by screw clamping. Through-coolant capability is supported via a 1\/8-27 NPT coolant hole, allowing direct coolant delivery to the cutting edge for improved chip evacuation and tool life in demanding materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for precision internal diameter work in production and job-shop turning environments. It handles a minimum bore diameter of 0.77 inches and a maximum bore depth of 1.875 inches, making it appropriate for short, tight-tolerance bores. The minimum bore diameter is reduced to 0.25 inches when used with a diamond insert cartridge configuration. It is installed and set up by machinists and CNC operators working to close bore tolerances on lathes equipped with tool turrets or block-style holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting orientation for applications requiring reverse-spindle or back-boring setups\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 1\/8-27 NPT coolant port for direct cutting-zone cooling and chip control\u003c\/li\u003e\n\u003cli\u003eAccepts CP.. 21.51 series inserts held by screw clamping for repeatable indexing\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability and vibration damping in standard boring applications\u003c\/li\u003e\n\u003cli\u003eBack of bar to cutting edge measures 0.406 inches, enabling precise tool offset setup\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter reduces to 0.25 inches with diamond insert cartridge configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CP.. 21.51 series indexable inserts in A10SCLPL2 toolholder-compatible setups.

Power down and lock out the machine spindle before changing inserts or setting tool offsets. Ensure the shank is fully seated and clamped to the specified overhang to minimize deflection. Connect the coolant port to the machine through-coolant supply using the 1\/8-27 NPT thread; verify coolant pressure and flow before running production parts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A10SCLPL2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.77 inches (19.56 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: 1.875 inches (47.63 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches (254 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CP.. 21.51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Size\u003c\/strong\u003e: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754358964530,"sku":"7000438","price":313.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e195ec9ee5a7ae94d154ff55dc8037e_151cfec7-633f-4a46-a7b2-f775534c864b.jpg?v=1788944676","url":"https:\/\/voomisupply.com\/products\/hertel-7000438-indexable-boring-bar-left-hand-through-coolant","provider":"Voomi Supply","version":"1.0","type":"link"}
