If the chip bird-nests, increase the feed by 10%—the **GH730** grade has the toughness to handle it. **BEYOND CNC** - Industrial Strength Precision.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size: 10px; color: #888; text-align: center; margin-top: 10px;\"\u003e© Authored by Beyond Li - CNC Technical Director\u003c\/p\u003e","brand":"Tungaloy","offers":[{"title":"WGE40 GH730","offer_id":46127288123564,"sku":"WGE40R GH730","price":134.85,"currency_code":"USD","in_stock":true},{"title":"WGE40R GH730","offer_id":46127288156332,"sku":"WGE40R GH731","price":134.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/Tungaloy_WGE40_WGE40R_GH730_4mm_External_Grooving_and_Parting_Insert.jpg?v=1775828274","url":"https:\/\/cnchome-beyond.com\/products\/tungaloy-wge40-wge40r-gh730-4mm-grooving-insert","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
