The downward tilt of the insert provides proper side clearance, allowing you to use all six cutting edges—three per side—before needing a replacement. The 3\/8″ shank fits Sherline’s P\/N 7600 tool post (not included).\u003c\/h3\u003e\n\u003ch3 data-start=\"780\" data-end=\"812\"\u003eWhy Use Ceramic Inserts?\u003c\/h3\u003e\n\u003ch3 data-start=\"814\" data-end=\"1215\"\u003eCeramic cutting tools are a powerful addition to the modern machinist’s toolbox. Though more brittle than high-speed steel (HSS) or carbide, ceramic inserts excel at cutting hardened steels and other tough materials, especially at higher spindle speeds. This makes them ideal for jobs that would otherwise be extremely difficult or impossible—such as turning down the shank of an end mill.\u003c\/h3\u003e\n\u003ch3 data-start=\"1217\" data-end=\"1324\"\u003eThis insert’s large nose radius helps achieve an excellent surface finish, particularly when profiling.\u003c\/h3\u003e\n\u003cul data-start=\"1326\" data-end=\"1666\"\u003e\n\u003cli data-start=\"1326\" data-end=\"1505\"\u003e\n\u003ch3 data-start=\"1328\" data-end=\"1378\"\u003eEach insert offers six usable cutting edges:\u003c\/h3\u003e\n\u003cul data-start=\"1381\" data-end=\"1505\"\u003e\n\u003cli data-start=\"1381\" data-end=\"1436\"\u003e\n\u003ch3 data-start=\"1383\" data-end=\"1436\"\u003eRotate 120° to access a new edge (3 per side), then\u003c\/h3\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1439\" data-end=\"1505\"\u003e\n\u003ch3 data-start=\"1441\" data-end=\"1505\"\u003eFlip the insert for 3 more cutting points on the opposite face\u003c\/h3\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1506\" data-end=\"1666\"\u003e\n\u003ch3 data-start=\"1508\" data-end=\"1666\"\u003eIn comparison, traditional carbide inserts offer only 2–4 cutting edges, making ceramic inserts cost-effective over time, despite the higher upfront cost.\u003c\/h3\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"1982\" data-end=\"2244\"\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003c\/div\u003e","brand":"Sherline","offers":[{"title":"Default Title","offer_id":47044349132996,"sku":null,"price":125.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0565\/1778\/7844\/files\/Screenshot2026-10-16at9.57.08PM_41c6e80e-ef50-4241-8d60-296d3e6c87cf.png?v=1792265933","url":"https:\/\/cardontools.com\/products\/sherline-p-n-30880-1-4-20-x-5-drawbolt-draw-bar-with-machined-washer-copy","provider":"Cardon Tools","version":"1.0","type":"link"}
