Built from M35 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting through tough materials. The 8.4 mm diameter bit features a 130-degree conical point with web thinning for improved centering and reduced thrust at entry. Overall length is 3.11 inches with a flute length of 1.46 inches and a maximum drilling depth of 0.94 inches. The parabolic flute geometry promotes efficient chip evacuation. This bit is designed to be installed and operated by machinists, tool-and-die technicians, and maintenance professionals working with ferrous and non-ferrous metals.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production drilling in cast iron, non-ferrous metals, stainless steel, and general steel. The screw machine length format provides added rigidity compared to jobber-length bits, making it well suited for drill press, CNC machining center, and turret lathe applications where shorter flute length and reduced deflection are priorities. The straight-cylindrical shank accepts standard drill chucks and collet holders. Series A1149XPL is a universal performance offering conforming to DIN 1897 and ISO standards, covering the 8.00 to 9.50 mm diameter range grouping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt construction for heat resistance and edge retention in hard metals\u003c\/li\u003e\n\u003cli\u003e130-degree conical point with web thinning reduces thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast, reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity and reduced deflection versus jobber bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eMeets DIN 1897 and ISO standards with h8 diameter tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces.

Secure the shank fully in a properly sized chuck or collet before operation and verify runout is within acceptable limits. Always follow machine guarding requirements and wear appropriate eye protection per applicable shop safety standards. Do not exceed the rated speed for the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.4 mm (0.3307 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79 mm (3.11 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 37 mm (1.46 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 24 mm (0.94 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42 mm (1.65 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.96 mm (0.077 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.4 mm (0.3307 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\u003ePoint Type\u003c\/strong\u003e: Conical with U-grind\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, web-thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1149XPL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\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: 5236470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51738597916978,"sku":"5236470","price":68.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f3206ec46db75e905bdab5426ee5e69_fce74ada-51d6-4e30-beff-02ee3302ff1f.jpg?v=1788801539","url":"https:\/\/voomisupply.com\/products\/walter-titex-5236470-screw-machine-drill-bit-8-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
