It measures 3\/8 inch (0.3750 inch) in diameter with a 5-inch overall length and a 3-5\/8-inch flute length. The bit is ground from high speed steel with a bright, uncoated finish and features a 135-degree split-point tip that reduces walking and requires no center punch on most workpieces. The right-hand spiral flute geometry clears chips efficiently during drilling. This bit is sized and built for heavy-duty use and meets NAS 907 Type B standards.\u003c\/p\u003e\u003cp\u003eThe C11621 is suited for drilling aluminum and similar non-ferrous metals, as well as general-purpose drilling in light steel and plastics. It fits standard drill chucks via its straight-cylindrical shank with a 3\/8-inch shank diameter. Machinists, maintenance technicians, pipefitters, and HVAC fabricators commonly use jobber-length bits in this size range for field and shop work. The regular spiral type provides balanced feed rates across a variety of drill press, hand drill, and mill applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces drill walking and improves hole accuracy without a center punch\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for heavy-duty drilling applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for aluminum and general-purpose materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral and 2-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and extends tool life\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any 3\/8-inch or larger keyed or keyless drill chuck.
