Built from cobalt vanadium high speed steel with a bright uncoated finish, it measures 0.248 inches in diameter with an overall length of 2.75 inches. The 130-degree split point and web-thinned, tapered web geometry reduce entry force and improve centering accuracy on tough workpieces. A parabolic flute design promotes efficient chip evacuation at a 3xD flute-to-diameter ratio. The straight cylindrical shank provides secure chuck engagement. This bit is intended for use by machinists, tool and die tradespeople, and industrial maintenance professionals working with precision drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for universal performance across a range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Its screw machine length profile makes it well suited for close-quarters drilling and use in drill presses, CNC machines, and manual lathes where a shorter flute length improves rigidity and reduces deflection. The Series A1148 designation reflects compliance with DIN, ISO, and BS standards, making it appropriate for precision manufacturing environments where dimensional tolerances are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt vanadium high speed steel construction for strength in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e130-degree split point with web thinning for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute at 3xD ratio for improved chip removal in deep-hole applications\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with or without cutting fluids\u003c\/li\u003e\n\u003cli\u003eMeets DIN, ISO, and BS standards for dimensional accuracy and performance grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement drill bit for use in standard straight-shank drill chucks across drill presses, CNC drilling centers, and manual machine tools requiring a 0.248-inch diameter bit in the Series A1148 configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance tradespeople familiar with machine tool operation. Secure the shank fully in the chuck and verify runout before drilling. Power down and de-energize all machine tools before changing bits. Do not exceed the rated maximum drilling depth of 0.800 inches per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.219 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.800 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: 0.058 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.00000 inches\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: 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\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: 5057216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728531259698,"sku":"5057216","price":163.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_f59f988a-7f7f-485d-8fcb-65bd897f8de5.jpg?v=1788692817","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057216-screw-machine-drill-bit-0-248-in","provider":"Voomi Supply","version":"1.0","type":"link"}
