Manufactured from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit features a parabolic flute geometry and a 130-degree split point that reduces walking and promotes clean entry. At 0.3281 inches (21\/64 inch) in diameter with an overall length of 3-1\/8 inches and a flute length of 1-7\/16 inches, it is built for short-reach, high-precision applications where rigidity and chip evacuation matter. A web-thinned, tapered web configuration reduces thrust and improves hole quality across a wide range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machining and fabrication environments where consistent, accurate holes are required in cast iron, stainless steel, carbon steel, hard materials, and non-ferrous metals. Its screw machine length profile makes it a practical choice for drill press work, CNC operations, and hand-held power tool use where reduced overhang and greater stability are priorities. The parabolic flute design promotes efficient chip removal at higher feed rates, making it effective in production drilling scenarios handled by machinists and metalworking professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt Vanadium High Speed Steel construction for heat resistance and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003e130-degree split point reduces center punch requirement and minimizes drill walking\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes rapid chip evacuation at aggressive feed rates\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and improves hole finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight-cylindrical shank for compatibility with standard chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN, ISO, BS, and DIN specification standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks; suitable for drilling cast iron, hard materials, non-ferrous metals, stainless steel, and carbon steel as specified by the manufacturer for Series A1148.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit should be performed by qualified machinists or metalworking tradespeople familiar with proper chuck mounting procedures. Ensure the drill press, CNC spindle, or power tool is fully powered down and secured before inserting or removing the bit. Use appropriate cutting fluid or coolant for the workpiece material when drilling stainless steel or hard alloys to extend tool life. Always verify chuck capacity and shank seating before beginning a drilling operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 21\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.3281 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0765 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\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\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.00000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5057170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51742162026802,"sku":"5057170","price":42.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_899efdef-6482-4a71-888b-95e5a26d75ce.jpg?v=1788835685","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057170-screw-machine-drill-bit-21-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
