This allows higher feed rates (f) and higher impact resistance during medium cutting compared to a 0.4 mm radius.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cdiv class=\"faq-q\"\u003eQ: What size hole diameter and screw does a TCMT110208 insert require?\u003c\/div\u003e\n\u003cdiv class=\"faq-a\"\u003eA: The TCMT110208 insert has a 2.8 mm center hole (D1) and uses standard M2.5 screw clamping systems (e.g., M2.5 x 6 screws) on ISO 11-size holders.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cdiv class=\"faq-q\"\u003eQ: Why is AC820P coating superior for continuous steel turning?\u003c\/div\u003e\n\u003cdiv class=\"faq-a\"\u003eA: AC820P incorporates Absotech Platinum technology, combining ultra-dense TiCN and nano-structured Al2O3 layers. This significantly lowers thermal conductivity into the carbide core and resists high-temperature flank wear.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTroubleshooting Quick Reference\u003c\/h3\u003e\n\u003cdiv class=\"table-responsive\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eProblem Encountered\u003c\/th\u003e\n\u003cth\u003eProbable Cause\u003c\/th\u003e\n\u003cth\u003eRecommended Solution\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlank Wear Accelerating Rapidly\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCutting speed Vc exceeds optimal range or cooling is insufficient\u003c\/td\u003e\n\u003ctd\u003eLower cutting speed Vc by 10-15% or verify flood coolant pressure at the cutting zone.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTool Vibration \/ Chatter Marks\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFeed rate f is too high for the 0.8mm radius or boring bar overhang is excessive\u003c\/td\u003e\n\u003ctd\u003eReduce feed rate slightly or decrease depth of cut ap to lower radial pressure.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLong Ribbon Chips Wrapping Tool\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDepth of cut ap is too shallow to engage the SU chip breaker wall\u003c\/td\u003e\n\u003ctd\u003eIncrease depth of cut ap above 0.5 mm to allow active chip curling.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c!-- Grade Comparison \u0026 Authority Tip --\u003e\n\u003cdiv class=\"tip-box\"\u003e\n\u003cdiv class=\"tip-title\"\u003eGrade Comparison Tip \u0026amp; Certified Standards Reference\u003c\/div\u003e\n\u003cp\u003eUnder ISO 513:2012 classification standards, SUMITOMO AC820P Absotech Platinum CVD coated grade delivers top-tier performance for medium-to-high speed turning of ISO P05–P25 carbon steels and alloy steels.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sumitomo","offers":[{"title":"Default Title","offer_id":43396364173484,"sku":"TCMT110208N-SU AC820P","price":94.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/SUMITOMO_TCMT110208N-SU_AC820P_CVD_Coated_Carbide_Turning_Insert.jpg?v=1787473663","url":"https:\/\/cnchome-beyond.com\/products\/sumitomo-tcmt110208n-su-ac820p","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
