It measures 2.875 inches overall, with a 1.75-inch spiral flute length and a straight-cylindrical shank diameter of 0.136 inches. The 135-degree split point reduces walking on entry and cuts cleanly through steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Web thinning and a tapered web configuration reduce thrust requirements and improve chip evacuation. This is a general-purpose, heavy-duty bit suited for production and maintenance drilling operations performed by machinists, millwrights, and skilled tradespeople.\u003c\/p\u003e\n\u003cp\u003eThe 5999122 is designed for drilling operations in ferrous and non-ferrous workpiece materials across a broad range of shop and field applications. Its regular spiral and two-flute geometry make it effective in handheld drills, drill presses, and CNC setups where a standard jobber-length profile is required. The bit is rated for use in steel, stainless steel, cast iron, non-ferrous metal, superalloys, and titanium, conforming to NAS 907 specification and meeting ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 29 wire size, 0.1360-inch decimal diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree standard split point minimizes walking and reduces entry burr\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and helps resist corrosion during storage\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers cutting thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, two-flute design suits general-purpose drilling in a wide range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber length drill bit compatible with standard straight-shank drill chucks in handheld drills, drill presses, and CNC machines.

Apply cutting fluid appropriate to the workpiece material to extend tool life, particularly when drilling stainless steel, superalloys, or titanium. Do not exceed the manufacturer-rated maximum drilling depth of 1.75 inches per pass; retract periodically to clear chips. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear 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 Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 13xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51721724199218,"sku":"5999122","price":45.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_134ba028-5e7a-48df-a15b-04ff1eafec9a.jpg?v=1788579932","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999122-no-29-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
