Built on the DC160 series platform with an X-treme Evo point geometry, this bit features a 140-degree drill point angle that reduces thrust and improves hole entry accuracy. The bit measures 3.11 inches overall length with a 0.25-inch (6.35 mm) cutting diameter, a straight-cylindrical shank diameter of 0.315 inches, and a flute length of 1.34 inches. The right-hand spiral flutes and Universal Advance performance classification make this a workhorse choice for production machining environments. It is installed and used by machinists and tool-and-die professionals working with CNC and manual drill setups.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine length drilling in cast iron and steel workpieces. The 3xD flute-by-diameter ratio and 24 mm maximum drilling depth (approximately 0.945 inches) make it appropriate for through-holes and shallow blind holes in production or maintenance machining contexts. The coated solid carbide construction supports consistent performance in both interrupted and continuous cut conditions on harder workpiece materials. Typical applications include component fabrication, fixture work, and production line drilling operations where tight diameter tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree X-treme Evo point geometry reduces drill thrust and improves entry precision\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.315 inches diameter for secure chuck or collet holding\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with 3xD ratio for efficient chip evacuation in short-depth holes\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN and ISO standards with m7 diameter tolerance for consistent fit\u003c\/li\u003e\n  \u003cli\u003eUniversal Advance performance rating suitable for cast iron and steel workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification screw machine length drill bit for use in standard drill chucks, collet holders, and CNC tool holders accepting a 0.315-inch straight-cylindrical shank.

Power down and de-energize the machine spindle completely before mounting or removing the bit from the chuck or collet. Solid carbide tooling is brittle compared to high-speed steel alternatives and should not be subjected to side loading or impact during setup. Verify spindle speed, feed rate, and workpiece clamping are appropriate for the material and drill diameter before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-treme Evo\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm (1.34 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 24 mm (0.945 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, 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: DC160\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Universal Advance\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: 0.038 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: 7377130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51754363453746,"sku":"7377130","price":182.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc29d20dd14dff40e8ee39f54234ed74_2e54d20d-b81a-4748-8766-861c938fd1a0.jpg?v=1788944733","url":"https:\/\/voomisupply.com\/products\/walter-titex-7377130-screw-machine-drill-bit-letter-e","provider":"Voomi Supply","version":"1.0","type":"link"}
