Built from high-speed steel (HSS) with a bright uncoated finish, this bit features a 135-degree split point and a parabolic spiral flute for efficient chip evacuation and reduced walking on entry. The straight-cylindrical shank measures 5\/16 inch in diameter and is compatible with standard drill chucks. Overall length is 4.5 inches with a flute length of 3.1875 inches, giving adequate reach for most production and maintenance drilling tasks. This is a heavy-duty, web-thinned bit conforming to ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It fits standard shop and field drilling applications where a jobber-length bit is appropriate. The QC21P series is positioned as a heavy-duty general-purpose option for machinists, maintenance technicians, pipefitters, and fabricators working on structural and mechanical assemblies. It is sold individually and is well-suited for both production environments and service truck use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch (0.3125 inch) diameter with matching straight-cylindrical shank\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walk and cutting pressure on entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright uncoated finish\u003c\/li\u003e\n  \u003cli\u003eParabolic spiral flute with tapered web for improved chip clearing\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design reduces thrust load when drilling harder materials\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry; QC21P heavy-duty series\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 any standard 3\/8-inch or larger keyed or keyless drill chuck accepting a 5\/16-inch straight-cylindrical shank.

Wear appropriate eye protection and secure the workpiece to prevent rotation. Use cutting fluid or coolant on harder materials such as stainless steel or superalloys to extend tool life, as this bit does not have a through-coolant channel. Inspect the cutting edges for wear before each use and replace when chipping or dulling is evident to maintain hole quality and operator safety.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\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\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.1875 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5996792\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693684621618,"sku":"5996792","price":22.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_700a0064-127c-4b18-8cd4-3015470313fc.jpg?v=1788316047","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996792-jobber-drill-bit-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
