The bit is ground from high speed steel and finished with a bronze coating to reduce friction and extend service life. A 135-degree split point starts on contact without a center punch and reduces thrust compared to a standard 118-degree point. Web thinning further lowers cutting resistance at the chisel edge. At 2.5 inches overall length with a 1.4375-inch flute length, this is a standard jobber proportion suited to hand-held drills, drill presses, and CNC lathes alike. Licensed machinists, tool-and-die techs, and maintenance mechanics are the typical users.\u003c\/p\u003e\u003cp\u003eThis bit belongs to the HX10-HX15-HX18 series and is rated for drilling into steel, stainless steel, cast iron, superalloys, and titanium — material codes P, M, K, and S in ISO classification. The straight-cylindrical shank at 0.1015 inches diameter seats in standard keyless or keyed chucks without adapters. Maximum drilling depth matches the flute length at 1.4375 inches. The 14xD flute-to-diameter ratio provides adequate chip clearance for these workpiece materials without requiring coolant-through capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 38 wire size, 0.1015 inches decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for self-starting entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bronze coating for reduced friction\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes, regular helix, tapered web configuration\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the HX10-HX15-HX18 series.

Secure the workpiece firmly before drilling to prevent walking at entry. Follow shop-specific speeds and feeds for the workpiece material being drilled. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 38\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4375 inches (1-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0625 inches (1-1\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.4375 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: Spiral, Regular Helix\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 14xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HX10-HX15-HX18\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: 0.01 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: 5995860\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51724039356722,"sku":"5995860","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81de5d15882edb9af16c3e5a7a8ee62a_1d0df959-a442-46e2-838f-bda9c3b80114.jpg?v=1788612043","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995860-no-38-hss-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
