Built from M35 cobalt steel and finished with an AlCrN coating, this bit resists heat and wear during extended cutting operations. It features a 130-degree drill point angle with UFL point geometry and a parabolic flute design that improves chip evacuation and reduces cutting resistance. The straight-cylindrical shank measures 3.9 mm in diameter. Overall length is 2.95 inches with a flute length of 1.69 inches. Intended for use by machinists and metalworking trades requiring consistent hole quality in ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole drilling and stack drilling applications across a range of workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals. Its parabolic flute geometry and web-thinned point make it effective in production environments where chip control and tool life are priorities. The A1249XPL series is built to DIN 338 and meets ANSI and ISO standards, making it appropriate for both domestic and international specification work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating extends tool life in abrasive and high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle with UFL point geometry for clean entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes efficient chip evacuation in deep and stack drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting force at the point\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 specification with ANSI and ISO compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling into steel, stainless steel, cast iron, and non-ferrous metals.

Secure the shank fully in the chuck before operation and verify runout is within acceptable limits. Do not exceed the maximum recommended drilling depth of 1.42 inches without retracting to clear chips. This bit does not support coolant-through delivery — use external coolant or cutting fluid as appropriate for 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: 3.9 mm (0.1535 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.95 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43 mm (1.69 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 32 mm (1.26 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 36 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.90 mm (0.036 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.9 mm (0.1535 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: 5xD\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\u003ePoint Type\u003c\/strong\u003e: UFL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\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, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1249XPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 5236543\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51738722435378,"sku":"5236543","price":43.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/746deaa6a0536707ca0648bd8d527896_d4768bc1-87cc-45dd-98a8-87d91ce87fd6.jpg?v=1788803435","url":"https:\/\/voomisupply.com\/products\/walter-titex-5236543-cobalt-jobber-drill-bit-3-9-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
