Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit features a parabolic flute design and a 130-degree split point for fast chip evacuation and accurate hole entry. The straight-cylindrical shank provides secure chuck retention in standard drill presses, CNC machines, and handheld power tools. Licensed machinists, pipefitters, and mechanical contractors rely on this type of tooling for precision-diameter holes in tough base materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use on cast iron, stainless steel, hardened steel, non-ferrous metals, and other hard materials. The screw machine length format  -  shorter than a jobber-length bit  -  delivers added rigidity and reduced deflection in close-clearance setups, making it a practical choice for machine shop work, fabrication bays, and field mechanical service. The Series A1148 designation places it within a standardized product family built to DIN and ISO specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.332 inch (Letter Q) diameter, tolerance -0.00087 to 0.000 inches for consistent bore size\u003c\/li\u003e\n\u003cli\u003eCobalt Vanadium High Speed Steel construction for heat resistance and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes rapid chip clearing and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003e130-degree split point with web thinning for self-centering entry and reduced thrust load\u003c\/li\u003e\n\u003cli\u003eScrew machine length for enhanced rigidity and minimal deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eCompliant with DIN, ISO, and BS specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks and compatible with a wide range of drilling applications across cast iron, stainless steel, hard material, non-ferrous metal, and general steel workpieces.

Secure the shank fully in the chuck and confirm concentricity before drilling. Use appropriate cutting fluid or coolant for stainless steel and hard material applications to preserve edge life. Always wear eye protection and ensure the workpiece is properly clamped before starting the spindle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Q\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.332 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0775 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 5153730\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51740533588274,"sku":"5153730","price":31.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_00d9ab5c-ad27-4505-894a-c1dbb64f60b1.jpg?v=1788825744","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153730-screw-machine-drill-bit-0-332-in","provider":"Voomi Supply","version":"1.0","type":"link"}
