Built from vanadium high speed steel with a bright uncoated finish, this bit features a 130-degree split point and a parabolic flute geometry. The 5\/16 inch diameter and compact 3-1\/8 inch overall length make it well suited for stub-length applications where rigidity and hole accuracy are priorities. The web-thinned, tapered web construction reduces entry force and improves chip evacuation, making it a reliable choice for production drilling environments where consistency matters.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for right-hand cutting and is rated for use in aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. The straight-cylindrical shank fits standard drill chucks without adapters. It is appropriate for use in machine shop environments, maintenance and repair operations, and fabrication work where screw machine length drills are specified. The Series A1148 designation places it within a recognized high-performance product line conforming to BS and DIN specification standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch diameter with a tight tolerance range of -0.00087 to 0.000 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces walking and lowers thrust requirements at entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile accelerates chip removal and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves cutting efficiency across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003eVanadium high speed steel construction provides elevated hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3-1\/8 inch OAL) delivers added rigidity compared to jobber length bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for drilling aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel.

Ensure the workpiece is securely fixtured and the drill chuck is properly tightened before operation. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material. Inspect the cutting edges for wear or damage before each use and replace the bit if the split point or flute geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches decimal)\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\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3000 to 0.3500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: BS, DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 5057210\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51743371264306,"sku":"5057210","price":34.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c019f2bc6f00f5028fc55d7ebd96d7a.jpg?v=1788846310","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057210-screw-machine-drill-bit-5-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
