Built from cobalt and vanadium high speed steel with a bright, uncoated finish, this bit delivers rigidity and heat resistance needed when working through hard materials. The 130-degree split point reduces walking and allows for clean entry without a center punch in many setups. At 0.252 inches in diameter with a straight-cylindrical shank, it is sized for use in standard chucks and screw machine setups. Licensed machinists, tool and die technicians, and industrial maintenance professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for universal tool performance across a broad range of workpiece materials including cast iron, stainless steel, carbon steel, hard materials, and non-ferrous metals. The parabolic flute geometry at a 3xD flute-to-diameter ratio promotes efficient chip evacuation, reducing heat buildup and extending tool life during repeated drilling cycles. The overall length of 2-3\/4 inches and a maximum drilling depth of 0.800 inches make it suited for short-reach, high-production drilling operations typical in machine shops and fabrication environments. It conforms to DIN, ISO, and BS standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt and vanadium high speed steel construction for elevated heat resistance in hard material drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces thrust force and prevents bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes rapid chip evacuation and reduces clogging\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard drill chucks and screw machine spindles\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank drill chucks and screw machine spindles.

Ensure the workpiece is firmly secured and the spindle is at a complete stop before bit changes. Confirm chuck and collet clearances are appropriate for the 0.252-inch shank diameter before use. Coolant-through is not supported on this bit, so adequate surface-applied cutting fluid is recommended when drilling stainless steel or other hard materials at sustained feed rates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.252 inches\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 Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0588 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\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\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 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\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: 5057217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728630939954,"sku":"5057217","price":25.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_4291ad00-12c1-4c91-a5de-4815a926fd8f.jpg?v=1788694193","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057217-screw-machine-drill-bit-0-252-in","provider":"Voomi Supply","version":"1.0","type":"link"}
