The reduced shank permits use in portable drills and chucks that don’t accept full-diameter shanks, expanding the effective size range of your tooling without sacrificing concentricity or ease of changeover.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the reduced shank help in a standard drill chuck?\u003c\/h3\u003e\n\u003cp\u003eThe reduced shank design narrows the gripping portion to 1\/2\", allowing this 16.50mm diameter bit to be held securely in common chucks.
