It carries a Titanium Nitride (TiN) coating that increases surface hardness and extends tool life in demanding production environments. The bit measures 4-5\/16 inches overall length with a 2-1\/2 inch flute length, a 130-degree split point, and a straight-cylindrical shank with a 1\/4 inch shank diameter. The 130-degree point geometry promotes self-centering and reduces the need for a center punch on most steel workpieces. This bit is part of OSG Series 1500 and is used by machinists, maintenance technicians, and metalworking professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in steel and alloy steel applications and is suited for blind hole drilling, cross hole drilling, through drilling, and self-centering operations. The No. 4 wire gauge size corresponds to 0.2090 inch (5.31 mm) diameter. The regular spiral flute configuration supports efficient chip evacuation in standard drilling setups. Coolant-through capability is not available on this model. It is sold individually as a single-piece unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for increased heat and wear resistance in ferrous metals\u003c\/li\u003e\n  \u003cli\u003eTitanium Nitride (TiN) coating extends tool life and reduces friction\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point promotes self-centering and reduces walking on steel surfaces\u003c\/li\u003e\n  \u003cli\u003eR-thinned web with tapered web configuration reduces thrust force at entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber length drill bit for use in standard drill chucks and drill press setups accepting a 1\/4 inch straight-cylindrical shank.
