This 230mm \"Tri-Grind\" Forstner Bit Extension gives you serious drilling depth, with a clever shank that grips beautifully no matter how you mount it. It's a genuine best-of-both-worlds design, engineered to hold securely in a chuck, a collet, or a grub screw mount.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"text-md leading-[24px] font-regular pt-[9px] pb-0.5\"\u003e\u003cspan\u003eThe secret is in the \"Tri-Grind\" shank itself. Three flat facets deliver superb non-slip, torquey grip in a standard 3-jaw drill chuck. The three rounded faces between them self-centre beautifully in a collet-style chuck, while in a 10mm bore grub screw mount, the flat face gives the grub screws something solid to bite, and the opposing rounded face sits flush against the bore for true-centre every time.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"font-semibold pdf-heading-class-replace pb-0.5 text-lg leading-[30px]
