Built from vanadium high speed steel with a titanium nitride (TiN) coating, the bit delivers extended wear resistance and reduced friction across demanding drilling applications. The 130-degree split point (S-thinned) geometry reduces thrust and enables self-centering entry without a center punch. At 75 mm overall length with a 43 mm flute length, this is a standard jobber-length geometry suited to general-purpose production and maintenance drilling. The straight-cylindrical shank seats directly in standard drill chucks. Installed by machinists, maintenance technicians, and fabricators working in metal.\u003c\/p\u003e\u003cp\u003eThe OSG 62540 is rated for blind hole, cross hole, through drilling, and self-centering applications in steel (P), stainless steel (M), aluminum, aluminum alloy, and aluminum silicate (N) workpiece materials. The 4 mm diameter and regular spiral flute configuration make it a practical choice for light structural fabrication, machine shop operations, and field maintenance work where a reliable general-purpose drill bit is needed in smaller metric sizes. No coolant-through capability is required for most standard use cases with this series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction for toughness in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating extends tool life and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003e130-degree S-thinned split point for self-centering and reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 4 mm and compatible drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eTapered web configuration supports rigidity throughout the flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks accepting a 4 mm straight-cylindrical shank.

Ensure the shank is fully seated and the chuck is tightened before operation. Apply cutting fluid or light oil when drilling stainless steel or harder steel grades to extend tool life. Inspect the cutting edge for wear or chipping before each use and replace the bit if the TiN coating is fully worn at the point.\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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: +0 to -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\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\u003eSeries\u003c\/strong\u003e: 1600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 62540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753085141298,"sku":"62540","price":41.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d63d8ec466dc211fbae0fceba4aa5c3.jpg?v=1788932658","url":"https:\/\/voomisupply.com\/products\/osg-62540-jobber-drill-bit-4mm-tin-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
