The solid carbide shank gives it much higher stiffness than an equivalent steel bar of the same diameter, letting it work closer to the chatter limit.\u003c\/p\u003e\u003ch3\u003eKey specs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Carbide shank (C-prefix, higher rigidity than steel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert material:\u003c\/strong\u003e Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank diameter:\u003c\/strong\u003e 12mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall length:\u003c\/strong\u003e 150mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMin bore diameter:\u003c\/strong\u003e 16mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax boring depth:\u003c\/strong\u003e 20mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility \/ fitment\u003c\/h3\u003e\u003cp\u003eFits standard lathe tool posts sized to the bar's shank dimension.\u003c\/p\u003e\u003ch3\u003eApplication \/ use case\u003c\/h3\u003e\u003cp\u003eBest suited to boring holes from 16mm upward where extra reach or a heavier finishing cut is needed but a slender steel bar would deflect or chatter; the carbide shank's rigidity lets it hold size and finish over the full 20mm boring depth without the speed\/feed compromises a steel bar of the same 12mm diameter would need.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":44848588849360,"sku":"C12QSDQCR07","price":279.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/1876\/3216\/files\/original_692f08e3-f7da-4734-b5c8-2f9372e6e9f4.png?v=1786955133","url":"https:\/\/forrestdaletools.com.au\/products\/internal-boring-bar-c12q-sdqcr07-tungsten-12mm","provider":"Forrestdale Tools","version":"1.0","type":"link"}
