It measures 10.20 mm (0.4016 inches) in diameter with an overall length of 5-15\/64 inches (133.00 mm) and a flute length of 3-27\/64 inches (87.00 mm). The 135-degree split point reduces walking on entry and lowers thrust requirements compared to a conventional 118-degree point. The straw oxide finish provides mild lubricity and corrosion resistance during storage and cutting. Web-thinned construction and a tapered web improve chip clearance in deeper holes. This bit is suited for licensed machinists, tool-and-die technicians, pipefitters, and mechanical contractors working with ferrous metals.\u003c\/p\u003e\u003cp\u003eThe 5999699 is rated for general-purpose and heavy-duty drilling in steel (P), stainless and heat-resistant alloys (M), cast iron (K), non-ferrous metals (N), and high-temperature alloys (S) under standard shop conditions. The straight cylindrical shank accommodates standard keyless and keyed drill chucks on bench drills, CNC machining centers, and portable magnetic-base drills. The regular spiral flute geometry and 9xD flute-to-diameter ratio make this bit a practical fit for through-hole and blind-hole work in structural steel, plate, pipe, and fabricated assemblies. No coolant-through capability is present, so flood or mist coolant is applied externally when required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt HSS construction for elevated heat resistance in ferrous and hard-alloy drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walk and cutting thrust\u003c\/li\u003e\n\u003cli\u003eStraw oxide finish adds surface lubricity and storage corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web improves chip evacuation in deeper holes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without an adapter\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 and ANSI standards for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute jobber drill for general-purpose drilling applications in steel and compatible materials per DIN 338 and ANSI specifications.

Secure the shank fully in a calibrated chuck and verify runout before drilling. Apply appropriate cutting fluid or external coolant to manage heat buildup when drilling steel, as this bit does not support coolant-through delivery. Inspect the cutting edges for chipping or wear before each use and regrind or replace when edge geometry degrades to avoid workpiece damage or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.20 mm (0.4016 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-15\/64 inches (133.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-27\/64 inches (87.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.20 mm (0.4016 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8110 inches (46 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4252 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\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless, Cast Iron, Non-Ferrous, High-Temp Alloys (P, M, K, N, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999699\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714164228402,"sku":"5999699","price":35.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_1e214735-f1f4-46c0-b117-7738676a021a.jpg?v=1788497059","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999699-jobber-drill-10-20mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
