Built to DIN 338 and ANSI standards, it features a 135-degree split point that reduces walking on entry and lowers the thrust needed to start a hole. The straw oxide finish provides a degree of lubricity and heat resistance during high-speed cutting operations. At 5.2344 inches overall length with a 3.4219-inch flute length, it handles jobber-depth holes in a standard drill chuck or drill press spindle. Intended for use by machinists, maintenance technicians, and metalworking trades.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose drilling in steel, cast iron, aluminum, and non-ferrous alloys, consistent with its P, M, K, N, and S workpiece material codes. The web-thinned, tapered web design reduces cutting resistance and improves chip evacuation on through-holes and blind holes alike. It fits standard drill presses, CNC machining centers, and hand-held drilling equipment that accept a straight cylindrical shank. The 8xD flute-to-diameter ratio supports moderate drilling depths without the need for peck-drilling cycles on most material types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for elevated heat resistance in steel and hard alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers required thrust\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish adds lubricity and mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces cutting load\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and ANSI dimensional standards for interchangeable fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill compatible with any drill press, benchtop machine, or hand drill accepting a 10.50 mm (0.4134 inch) straight cylindrical shank.

Power down and lock out the machine before changing bits. Use cutting fluid or a suitable metalworking lubricant when drilling steel to prolong bit life and improve hole finish. Inspect the cutting edges for chipping or wear before each use; a worn 135-degree point should be reground or replaced rather than run at reduced feed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 10.50 mm (0.4134 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.2344 inches (133.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4219 inches (87.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4134 inches (10.5 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8110 inches (46 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4252 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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eMaterial\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\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: 5999705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51718170345778,"sku":"5999705","price":36.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_297aa3b0-1f55-4497-afb5-490b08c59078.jpg?v=1788550584","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999705-cobalt-jobber-drill-10-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
