Built from cobalt and vanadium high speed steel, it delivers the heat and wear resistance required when working through stainless steel, cast iron, hard materials, and non-ferrous metals. The 0.25 inch (1\/4 inch, Letter E) diameter bit features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduces walking at entry. With an overall length of 2-3\/4 inches and a flute length of 1-7\/32 inches, this bit fits standard screw machine length applications where a compact, rigid setup is needed. Manufactured to DIN and ISO standards, it is suited for production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in metalworking applications across industrial maintenance, fabrication shops, and mechanical contracting work. The screw machine length format offers increased rigidity compared to jobber-length bits, making it a practical choice for drilling in drill presses, CNC machines, and turret lathes. Primary workpiece materials include stainless steel, steel, cast iron, hard materials, and non-ferrous metals. The Series A1148 designation places it in a universal-performance tool family engineered for a wide cross-section of production drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt and vanadium high speed steel construction for heat resistance in tough materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces thrust and eliminates the need for a center punch on most metals\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes fast chip evacuation and reduces chip packing\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency and reduces torque\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS specification designations for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks and collets on drill presses, CNC machining centers, and turret lathes.

Secure the shank fully in the chuck or collet before operation and verify runout before drilling production parts. Always apply an appropriate cutting fluid when drilling stainless steel or hard materials to manage heat buildup. Replace the bit when cutting edges show signs of dulling to avoid work hardening the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch, Letter E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-7\/32 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 Length\u003c\/strong\u003e: 0.0583 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 and 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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Universal\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\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: 5057122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51743379980594,"sku":"5057122","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_932911ad-8ddd-48c0-81a3-820fb68db83a.jpg?v=1788846377","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057122-screw-machine-drill-bit-0-25in","provider":"Voomi Supply","version":"1.0","type":"link"}
