Built from vanadium high speed steel with a WD1 coating, this bit delivers improved wear resistance and cutting performance across a range of ferrous and non-ferrous materials. The 130-degree S-thinned point promotes self-centering and reduces thrust force at entry, making it well-suited for production drilling where accuracy and consistency matter. With an overall length of 75 mm and a flute length of 43 mm, this is a standard jobber-length tool sized for general-purpose use on manual and CNC drilling equipment.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use on steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The straight-cylindrical shank and 4 mm diameter make it compatible with standard drill chucks and collet holders used in both shop and field settings. Typical applications include blind hole drilling, cross hole drilling, and through-hole operations in light manufacturing, maintenance, and precision machining environments. The regular spiral flute geometry supports consistent chip evacuation without coolant-through capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction with WD1 coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with S-thinned web for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eSpiral flute with tapered web configuration promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, cross hole, and self-centering drilling applications\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, aluminum, aluminum alloy, and aluminum silicate.

Ensure the drill chuck or collet is fully secured and the workpiece is firmly clamped before beginning a cut. Verify spindle speed and feed rate are appropriate for the workpiece material before operation. Inspect the cutting edges for wear or damage before each use and replace the bit when signs of dulling are present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43 mm (1.693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: S-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 mm\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: 1650\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8655400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727609200946,"sku":"8655400","price":40.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b86cba55a58ae73f145fefc0bbdb8ce0.jpg?v=1788679930","url":"https:\/\/voomisupply.com\/products\/osg-8655400-jobber-drill-bit-4mm-hss-wd1-130-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
