Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it carries a wire gauge size of No. 29, which corresponds to 0.1360 inches in decimal. The 135-degree split point reduces walking on entry and lowers the thrust required to initiate a cut. Overall length is 2-7\/8 inches with a flute length of 1-3\/4 inches. The straight-cylindrical shank measures 1.125 inches in diameter and seats securely in standard drill chucks. This is a heavy-duty grade bit rated to NAS 907 Type B standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use on cast iron, stainless steel, and carbon steel workpieces in fabrication, maintenance, and mechanical assembly environments. The right-hand spiral flute with regular helix evacuates chips efficiently in through-hole and blind-hole drilling. The TiN coating extends tool life by reducing friction and surface heat at the cutting edge. This bit is appropriate for machinists, pipefitters, ironworkers, millwrights, and maintenance technicians working with metal substrates in both shop and field settings. It is sold individually and is compatible with standard drill presses, hand drills, and drill-motor setups that accept a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 29 diameter — 0.1360 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes bit walking on hard metals\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and extends tool life\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for cast iron, stainless steel, and steel workpieces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design improves chip clearance and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B specification — heavy-duty grade for production and MRO use\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 accepting a straight-cylindrical shank.

Ensure the shank is fully seated and secured in the chuck before operation. Appropriate cutting fluid or coolant should be applied when drilling stainless steel or hardened steel to manage heat buildup at the cutting edge. Inspect the cutting edges and TiN coating for wear before each use and replace the bit if chipping or excessive dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150ASP-TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41699\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727194587442,"sku":"41699","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df9345e9378271d5c6fee69a041441bf.jpg?v=1788674568","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-41699-jobber-drill-bit-29-wire-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
