Ground from high-speed steel with a steam oxide finish, this bit features a 118-degree standard point angle and a right-hand spiral flute configuration. The 5\/16-inch diameter matches a straight-cylindrical shank of equal diameter, making it compatible with standard three-jaw chucks. The tapered web with web-thinning reduces thrust force at the cutting point and helps maintain center accuracy. A licensed HVAC tech, plumber, electrician, or general trade professional will find this bit at home on metal fabrication, equipment mounting, and service work alike.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The Series R10 jobber-length format provides a balance between reach and rigidity for common trade drilling tasks. With a flute-to-diameter ratio of 10xD and a maximum drilling depth of 3.1875 inches, it handles typical hole depths encountered in sheet metal, structural steel, and pipe work without excessive deflection. The single-piece construction and ANSI-standard geometry make it a straightforward drop-in for any job requiring a 5\/16-inch hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel construction with steam oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and accurate starting\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral, two-flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e5\/16-inch straight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eOverall length of 4.5 inches with a 3.1875-inch flute length for adequate reach\u003c\/li\u003e\n\u003cli\u003eANSI-standard geometry; compatible with steel, stainless steel, cast iron, non-ferrous metals, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in any standard three-jaw chuck or drill press accepting a 5\/16-inch straight shank.

Power down and de-energize any equipment being drilled into before beginning work, in accordance with applicable lockout\/tagout procedures. Use cutting fluid when drilling stainless steel, superalloys, or titanium to extend bit life and manage heat. Do not exceed the rated maximum drilling depth of 3.1875 inches in a single pass; retract frequently to clear chips and prevent binding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1875 inches (3-3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\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: 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 5998756\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51716331569458,"sku":"5998756","price":56.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8285143b76113f15c5f987c3a55f96e2_9396efe0-11d5-4c24-873c-4e1070ec6a16.jpg?v=1788524493","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998756-jobber-drill-bit-5-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
