{"title":"HTC Solid Carbide Boring Tools","description":"\u003cp\u003eSmall-bore boring is where indexable tooling runs out of room. Below about half an inch there is no space to seat an insert and a screw, so the bar has to be ground from one piece — and in a bore that small, the bar is thin enough that its stiffness decides the result more than anything else in the setup. Solid carbide is roughly three times as rigid as steel, which is why these exist.\u003c\/p\u003e\u003cp\u003eWhat that rigidity buys is a bore that stays round and on size down its full depth instead of belling out at the mouth, and a finish that does not carry the chatter pattern a deflecting bar leaves behind.\u003c\/p\u003e\u003ch3\u003eWhat is in this range\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum bore:\u003c\/strong\u003e .090\" through .360\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank diameters:\u003c\/strong\u003e 1\/8\", 3\/16\", 1\/4\", 5\/16\" and 3\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e solid carbide, ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e made in the USA by HTC Mfg.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTwo habits pay off with any small boring bar: keep the overhang to the shortest length that reaches the bottom of the bore, and take the finishing pass light, because a thin bar deflects under load and a light cut deflects less.\u003c\/p\u003e\u003cp\u003eLarger bores: \u003ca href=\"\/collections\/rmc-boring-bars\"\u003eRMC Boring Bars\u003c\/a\u003e, \u003ca href=\"\/collections\/canela-boring-bars\"\u003eCanela Boring Bars\u003c\/a\u003e and \u003ca href=\"\/collections\/canela-psc-boring-bars\"\u003eCanela PSC Boring Bars\u003c\/a\u003e.\u003c\/p\u003e\u003cp style=\"background:rgba(237,139,0,.08);border-left:4px solid #ED8B00;padding:16px 20px;margin:24px 0;border-radius:4px;\"\u003e\u003cstrong\u003eNot sure which size or geometry you need?\u003c\/strong\u003e \u003ca href=\"mailto:info@fmcarbide.com\"\u003eEmail our technical team\u003c\/a\u003e with the bore diameter and depth — FM Carbide helps you machine better!\u003c\/p\u003e","products":[{"product_id":"htc-r-b-0","title":"Solid Carbide Boring Tool -
