Manufactured from high speed steel with a bronze coating, it features a 135-degree split-point angle and a web-thinned, tapered-web construction that reduces walking on contact and lowers thrust requirements. The straight-cylindrical shank measures 0.1990 inches in diameter. With an overall length of 3.625 inches and a spiral flute length of 2.4375 inches, this bit suits standard drill chucks and right-angle drill setups common in production and maintenance environments. Licensed tradespeople and machinists select this bit for drilling through steel, stainless steel, cast iron, and superalloys including titanium.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for right-hand cutting with regular-spiral, two-flute geometry and a maximum drilling depth of 2.4375 inches. It fits applications across metalworking, fabrication, and maintenance where wire-size precision is required. The No. 8 wire-gauge designation corresponds to a decimal diameter of 0.1990 inches, making it a common choice when working to close-tolerance hole specifications in steel and stainless steel assemblies. The Series HX10-HX15-HX18 designation covers the Precision Twist Drill bronze-coated high speed steel jobber family, dimensioned to ANSI standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces bit walk and lowers feed pressure on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered-web geometry improves chip evacuation in deep holes\u003c\/li\u003e\n\u003cli\u003eBronze coating provides lubricity and surface hardness for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eNo. 8 wire size, 0.1990-inch decimal diameter for close-tolerance hole work\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting with regular two-flute spiral; compatible with standard straight-shank chucks\u003c\/li\u003e\n\u003cli\u003eDimensioned to ANSI specification; Series HX10-HX15-HX18\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for steel, stainless steel, cast iron, and superalloys including titanium.

Secure the shank fully in the chuck before operating. Coolant-through is not supported on this bit; use appropriate cutting fluid applied externally when drilling stainless steel, cast iron, or superalloys to manage heat buildup. Inspect the cutting edges for wear before each use and replace when point geometry is compromised to maintain hole-size accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1990 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches (3-5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4375 inches (2-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.4375 inches (2-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1990 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches (1-3\/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\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HX10-HX15-HX18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 5995584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722914464050,"sku":"5995584","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28291d695eb6c90708270d4dadfdae7d_9bd56e39-a578-443e-9025-0b1b6e5a66f4.jpg?v=1788597821","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995584-no-8-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
