Designed for the Cut-Grip series, this insert delivers a 4.00 mm (0.1575 inch) cutting width with a maximum depth of cut of 0.40 mm (0.0157 inch). The uncoated, bright-finish CBN substrate is engineered specifically for machining hard materials, making it appropriate for hardened steels, cast irons, and similar difficult-to-cut workpieces. The neutral hand orientation and positive rake geometry with a 7-degree rake angle reduce cutting forces and promote clean chip evacuation. A K-style chip breaker is integrated into the insert geometry. Installation is performed via clamp-style insert holding. Machinists and CNC turning specialists are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis grooving insert is intended for hard-material turning applications where tight groove dimensions and surface finish consistency are critical. The 0.20 mm (0.0080 inch) corner radius and 30-degree lead angle support precision external grooving and parting operations on hardened workpieces. The Cut-Grip series tooling system this insert belongs to is a dedicated grooving platform used on CNC lathes and turning centers in production and job-shop environments. The GITM insert style and 400K020 size code identify the correct toolholder pocket geometry required for proper seating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCBN (cubic boron nitride) uncoated substrate rated for hard-material (H-code) workpieces\u003c\/li\u003e\n  \u003cli\u003e4.00 mm cutting width with a maximum depth of cut up to 0.40 mm per pass\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with 7-degree rake angle reduces cutting forces on hardened materials\u003c\/li\u003e\n  \u003cli\u003eK-style chip breaker for controlled chip formation in tight-tolerance grooving\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius supports precise groove profiles\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding for secure, repeatable seating in compatible Cut-Grip toolholders\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 insert identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ISCAR Cut-Grip series toolholders that accept GITM-style inserts with the 400K020 size code.

Use the appropriate torx or hex key to release and reseat the clamp to the toolholder manufacturer torque specification. Inspect the insert pocket and clamp for debris or wear before seating the new insert. CBN inserts are brittle and should not be dropped or subjected to impact during handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GITM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IB20H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cubic Boron Nitride (CBN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0080 inches)\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: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cut-Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 400K020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.69 inches (L) x 1.61 inches (W) x 0.63 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6404168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738213843250,"sku":"6404168","price":211.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e8bd76e7bfad12e47f7ce83ba3cf619.jpg?v=1788796828","url":"https:\/\/voomisupply.com\/products\/iscar-6404168-grooving-insert-gitm400k020k-ib20h-cbn","provider":"Voomi Supply","version":"1.0","type":"link"}
