The bit measures 15\/32 inch (0.4688 inch decimal) in diameter with a 5-3\/4 inch overall length and a 4-5\/16 inch flute length. The 135-degree split point reduces walking on entry and decreases thrust load, making it well suited for hand-held or machine-mounted drilling operations. An oxide and straw finish provides light lubricity and corrosion resistance during use. Web thinning at the tip further reduces cutting resistance. This is a heavy-duty, general-purpose bit built to NAS 907 and ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling into steel, stainless, cast iron, aluminum, nonferrous metals, and high-temperature alloys, covering primary workpiece material codes P, M, K, N, and S. It is a practical choice for HVAC fabricators, pipefitters, millwrights, and general metalworking shops requiring consistent performance in a 15\/32 inch size. The straight cylindrical shank fits standard drill chucks on drill presses, magnetic drills, and hand drills. The regular spiral flute geometry clears chips efficiently in through-hole and blind-hole applications across the R10CO-R15CO-R18CO series range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eOxide and straw finish adds surface lubricity and light corrosion protection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance at the tip\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 9xD flute-to-diameter ratio promotes reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ANSI standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the PRECISION TWIST DRILL R10CO-R15CO-R18CO series. Fits any standard drill chuck accepting a 15\/32 inch (0.4688 inch) straight cylindrical shank.

Secure the straight shank fully in the chuck and verify concentricity before operation. Coolant through is not supported on this bit; apply cutting fluid externally when drilling harder steels to manage heat buildup. Follow shop safety protocols and applicable ANSI machining guidelines when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/32 inch (0.4688 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt High Speed Steel\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches (5-3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.3125 inches (4-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.3125 inches (4-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4688 inch (15\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches (1-7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P, M, K, N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.083 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5998286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693065601330,"sku":"5998286","price":40.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48612cbca6d09eb9dfe2c82cf07b8e8a_0cc3b06c-5d3e-409c-89e9-7e4280b1c862.jpg?v=1788306862","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998286-cobalt-jobber-drill-15-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
