Built from vanadium high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. The 4.1 mm diameter translates to 0.1614 decimal inches, making it a precise intermediate size within the 4.00 to 5.00 mm range. The 120-degree split point with S-thinned web reduces thrust force and enables self-centering entry without a center punch. Overall length is 87 mm with a 43 mm flute length. Machinists, tool and die workers, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for blind hole, cross hole, and through-hole drilling operations in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The straight-cylindrical shank at 6.0 mm diameter seats securely in standard drill chucks and quick-change holders. The tapered web configuration and regular spiral flute geometry support efficient chip evacuation in both CNC machining centers and handheld drill applications. The Series 1600 designation places this bit within the OSG high-performance jobber line, making it appropriate for production environments where consistent hole quality and dimensional accuracy are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction with TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eS-thinned split point at 120 degrees reduces thrust and self-centers on entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute geometry for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 6.0 mm diameter fits standard chucks and holders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eSuitable for blind holes, cross holes, and self-centering drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece materials coded P, M, and N, corresponding to steel, stainless steel, and aluminum and aluminum alloys.

Ensure the machine is fully stopped and de-energized before changing tooling. Verify chuck jaws are clean and concentric to maintain the rated diameter tolerance. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling stainless steel or hard alloy materials to manage heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.1 mm (0.1614 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 87 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.0 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: 120 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\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\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: 1600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 62541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727758033202,"sku":"62541","price":53.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53c94c0b74a3c43445f081adbd23944d.jpg?v=1788681819","url":"https:\/\/voomisupply.com\/products\/osg-62541-jobber-drill-bit-4-1mm-tin-hss-120-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
