Built from cobalt and vanadium high speed steel, this bit handles cast iron, stainless steel, hard materials, and non-ferrous metals without sacrificing edge life. The 130-degree split point reduces walking and lowers thrust at entry, while the parabolic flute geometry improves chip evacuation and reduces heat buildup in deep cuts. At 2-29\/32 inches overall length with a 0.272-inch diameter (letter size I), it fits standard jobber chucks and screw machine setups common in production and maintenance machining environments. Licensed HVAC, plumbing, and mechanical contractors use this bit when drilling through structural steel, flanges, or heavy-gauge enclosures during system installation.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for screw machine and production drilling applications where shorter flute length and rigid geometry are needed for accuracy and cycle time. The straight-cylindrical shank seats in standard drill chucks without adapters. Its universal tool performance rating covers a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals, making it versatile for job-site and shop use. The web-thinned, tapered web configuration reduces cutting resistance and helps maintain hole quality when drilling into tough alloys. A maximum drilling depth of 0.900 inches suits most through-hole and moderate blind-hole tasks common in mechanical and trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt and vanadium high speed steel construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces thrust and prevents bit walking on curved or uneven surfaces\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with web-thinned, tapered web design improves chip flow and lowers heat in the cut zone\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides added rigidity and precision versus jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows visual wear monitoring during use\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS standards for dimensional accuracy and performance grade classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit screw machine drill bit for use with standard straight-cylindrical shank drill chucks; Series A1148 designation confirms compliance with DIN and ISO dimensional standards for 0.272-inch diameter screw machine length bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or licensed trade professional familiar with rotating cutting tools. Secure the shank fully in a properly sized drill chuck and confirm chuck runout is within tolerance before starting a cut. Always use appropriate cutting fluid or coolant when drilling stainless steel or hard materials, even though this bit does not have internal coolant-through capability. Follow applicable OSHA and shop safety standards for eye protection, workpiece clamping, and spindle speed selection based on material and diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.272 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-29\/32 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 Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0633 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\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\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\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\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 Materials\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\u003eTool Performance\u003c\/strong\u003e: Universal\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\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: 5153722\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51739975844146,"sku":"5153722","price":30.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_9d938397-9c96-49f2-a842-3afe9046ad5c.jpg?v=1788820949","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153722-screw-machine-drill-bit-0-272-in","provider":"Voomi Supply","version":"1.0","type":"link"}
