It carries the KCK20 grade designation with a CVD-applied TiCN and Al2O3 coating for wear resistance and thermal stability at the cutting edge. The insert features a neutral hand orientation and a 6.05 mm cutting width with a maximum depth of cut of 4.90 mm. The B-style chip breaker promotes controlled chip formation during interrupted and continuous grooving passes. Machining professionals and CNC operators use this insert in production turning environments where dimensional consistency and tool life are critical.\u003c\/p\u003e\u003cp\u003eThis insert fits Series A4 toolholders and is suited for grooving operations in materials classified under C3 and C4 material grades, including cast irons and hardened steels where CVD coatings provide a performance advantage. The G0605M0B insert size fits standard A4-series grooving systems. It is a single-use insert sold individually, with a minimum order quantity of 10 units. This insert is appropriate for shops running medium to high production volumes on CNC turning equipment where repeatable groove geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCK20 solid carbide grade with CVD-applied TiCN and Al2O3 multilayer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e6.05 mm cutting width with a maximum depth of cut of 4.90 mm\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible toolholder mounting\u003c\/li\u003e\n\u003cli\u003eB-style chip breaker for controlled chip evacuation during grooving\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.40 mm for groove root geometry control\u003c\/li\u003e\n\u003cli\u003eSeries A4 compatibility for direct fitment into matching toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Series A4 grooving toolholders.

Use the appropriate torque wrench and insert-clamping hardware specified by the toolholder manufacturer  -  do not overtighten the clamp screw. Inspect the insert pocket for chips or debris before seating the insert. Confirm insert orientation matches the neutral-hand designation of the toolholder before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 6.05 mm (0.238 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.90 mm (0.1929 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 4.00 mm to 5.00 mm (0.150 to 0.200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.1811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0605M0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3066053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741407150386,"sku":"3066053","price":603.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eddba3e9cc82c6a6e3d3238b24ef2bda.jpg?v=1788831329","url":"https:\/\/voomisupply.com\/products\/kennametal-3066053-grooving-insert-kck20-carbide-neutral","provider":"Voomi Supply","version":"1.0","type":"link"}
