Manufactured in the ACK300 grade with a PVD coating process, this insert delivers wear resistance and cutting performance across a wide range of workpiece materials. It features a parallelogram shape with a 0.2953-inch inscribed circle, a thickness of 0.1378 inches, and a corner radius of 0.0236 inches. The G chipbreaker geometry promotes controlled chip evacuation during drilling operations. Cutting direction is right hand. This insert is used by machinists and tooling professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for indexable drilling applications across universal workpiece material categories, including cast iron, steel, non-ferrous metals, stainless, and high-temperature alloys, as indicated by material codes K, M, N, P, and S. It fits WDXT07-series insert seats in compatible indexable drill bodies. The insert size code is 07, with an insert size designation of 073506. Typical applications include through-hole and blind-hole drilling where consistent insert geometry and coating durability are required across medium to high production volumes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eACK300 grade solid carbide with PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eParallelogram insert shape with WDXT07G geometry for precise seating\u003c\/li\u003e\n\u003cli\u003eG chipbreaker for controlled chip formation and evacuation\u003c\/li\u003e\n\u003cli\u003e0.0236-inch corner radius reduces cutting-edge stress at entry and exit\u003c\/li\u003e\n\u003cli\u003eCompatible with universal workpiece material codes K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in indexable drill bodies that accept WDXT07-style insert seats.

Power down and lock out the machine spindle before seating or replacing inserts. Use the manufacturer-recommended torx or hex key to secure the clamping screw to the insert pocket — do not overtighten. Inspect the insert pocket for wear, chips, or debris before seating a new insert to ensure proper contact and accurate cutting geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WDXT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACK300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2953 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1378 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0236 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 073506\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 07\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1AHD021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51734645702962,"sku":"1AHD021","price":178.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a2804a234c0dfc53cffabf718e4f974_bb8009ed-2ae0-4c23-9bed-5b50a3fc5650.jpg?v=1788764343","url":"https:\/\/voomisupply.com\/products\/sumitomo-1ahd021-indexable-drill-insert-wdxt07g-ack300","provider":"Voomi Supply","version":"1.0","type":"link"}
