Built to the A-SCLD-S toolholder style, it accepts CD.. 120605 inserts secured by a screw-clamp holding method, providing repeatable positioning and quick insert changes at the machine. The bar features a 0.204 inch minimum bore diameter and a 3\/8 inch shank diameter, with an overall length of 2.5 inches. A positive rake geometry with a 5-degree rake angle and a 95-degree lead angle reduces cutting forces and promotes clean chip evacuation in tight bore profiles. Coolant-through capability via a 0.040 inch coolant hole delivers fluid directly to the cutting zone for thermal control and chip flushing.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for small-diameter internal finishing and semi-finishing passes in steel, stainless, cast iron, and non-ferrous alloys. It fits applications where bore depth does not exceed 0.500 inches and where a right-hand cut orientation is required. Machinists and CNC turning specialists use this bar in production and job-shop environments where consistent tool life and insert indexability are priorities. The screw-clamp design supports fast insert swaps without removing the bar from the holder, reducing downtime between passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccepts CD.. 120605 inserts with screw-clamp holding for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e0.204 inch minimum bore diameter enables access to small internal features\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with 0.040 inch coolant hole for direct cutting-zone fluid delivery\u003c\/li\u003e\n  \u003cli\u003ePositive rake at 5 degrees with 95-degree lead angle reduces radial cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard CNC lathe setup\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter fits common boring bar holders and quick-change tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CD.. 120605 series inserts.

Ensure the machine spindle is fully stopped and the control is in E-stop or safe state before changing inserts or mounting the bar. Secure the shank in the boring bar holder to the torque specification listed in the tooling system documentation — do not over-torque the insert screw, as this can damage the screw or pocket seat. Verify runout and tool offset after mounting before taking the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-SCLD-S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.204 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.104 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 95 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CD.. 120605\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\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: 0.040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0882 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: 1937960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731062260018,"sku":"1937960","price":291.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8947440d52d29769693e2ab9031bef27_088f6174-7dd2-4854-8094-cafdc5ef9e00.jpg?v=1788726440","url":"https:\/\/voomisupply.com\/products\/kennametal-1937960-indexable-boring-bar-3-8-inch-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
