This single-sided, square-profile insert features a helical cutting edge style and a positive rake geometry that reduces cutting forces and heat generation at the tool-workpiece interface. The AlTiN and TiN dual-layer PVD coating, branded as ISCAR Sumotec, delivers strong wear resistance and thermal stability. With four available cutting edges per insert and a chip breaker designation of ATR, this insert is suited for roughing and semi-finishing passes across a range of difficult materials including steel, stainless steel, superalloys, and titanium.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in milling applications on CNC machining centers and manual mills where consistent depth-of-cut control and long tool life are priorities. It fits into ISCAR HELIOCTO series cutter bodies, specifically confirmed compatible with the HOF-R06 and HOE-R06 cutter series. Primary workpiece material codes are P, M, and S, covering steel, stainless steel, and superalloys and titanium. The insert is held in place by screw mounting, which is standard for this insert style. Typical users are machinists and CNC operators in job shops, aerospace production, and general metalworking environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC830 grade solid carbide with AlTiN and TiN Sumotec PVD dual-layer coating for high wear resistance\u003c\/li\u003e\n\u003cli\u003eHelical cutting edge style with positive rake geometry to reduce cutting forces\u003c\/li\u003e\n\u003cli\u003eATR chip breaker configuration for effective chip control in steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert maximizes cost efficiency per insert\u003c\/li\u003e\n\u003cli\u003eScrew-mount insert holding method for secure, repeatable seating in the cutter body\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 standards for insert identification and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eConfirmed compatible with ISCAR HELIOCTO series cutter bodies HOF-R06 and HOE-R06.

Use the correct torx or hex key as specified by the cutter body manufacturer when seating the insert screw — do not overtighten, as this can fracture the carbide insert body. Inspect the insert pocket and seating surface for chips or debris before mounting. Replace all inserts in a cutter body at the same time when possible to maintain balanced cutting performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN and TiN (Sumotec PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELIOCTO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ATR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 140405\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.195 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5591 inches (14.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5394 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0197 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.217 inches (5.51 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5607691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51752016019762,"sku":"5607691","price":373.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ed8cf33667aff3dbe6d90449b28642e.jpg?v=1788925240","url":"https:\/\/voomisupply.com\/products\/iscar-5607691-semt-140405atr-ic830-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
