Built from cobalt vanadium high speed steel, it delivers the hardness and heat resistance required when cutting through stainless steel, cast iron, hard materials, and non-ferrous metals. The bit measures 0.4252 inches in diameter with an overall length of 3.75 inches and a flute length of 1.84 inches. A 130-degree split point reduces walking and lowers entry force, while the parabolic flute geometry improves chip evacuation at depth. Licensed machinists, tool-and-die professionals, and industrial maintenance technicians are the primary installers of this type of bit.\u003c\/p\u003e\n\u003cp\u003eThe 5057127 is suited for screw machine operations and general-purpose drilling where a compact stub-length bit is preferred over jobber or taper length. The 3xD flute-to-diameter ratio and web-thinned, tapered web design allow efficient drilling to a maximum depth of 1.100 inches. It performs across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals, making it a reliable choice for production environments and maintenance shops alike. The straight cylindrical shank seats in standard drill chucks without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt vanadium high speed steel construction for heat resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces drill walk and cutting entry force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry improves chip evacuation at depth\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements and extends tool life\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS standards for dimensional accuracy and tool performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use across primary workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals.

Secure the shank fully in the chuck and verify runout before beginning a cut. De-energize and lock out all rotating equipment before changing tooling per applicable machine safety standards. Do not exceed the manufacturer-rated maximum drilling depth of 1.100 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0991 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00106 to 0.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5057127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51748436050226,"sku":"5057127","price":78.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_3f29a382-7364-418d-a6ee-72038eda7972.jpg?v=1788893782","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057127-screw-machine-drill-bit-0-4252-in","provider":"Voomi Supply","version":"1.0","type":"link"}
