Built from Vanadium High Speed Steel (VHSS) with a Titanium Nitride (TiN) coating, it delivers extended tool life and reduced friction in demanding production and maintenance environments. The 130-degree split point (S-thinned web) eliminates the need for a center punch on most metals, improving hole accuracy and reducing thrust. At 3.5 mm in diameter with a 71 mm overall length and a 39 mm flute length, it fits standard drill chucks and CNC toolholders with a 4 mm straight-cylindrical shank. Machinists, maintenance technicians, and fabricators use this bit for blind holes, cross holes, and self-centering applications.\u003c\/p\u003e\u003cp\u003eThe OSG 62535 is suited for drilling steel, stainless steel, aluminum, aluminum alloys, and aluminum silicate. It is commonly used in light manufacturing, metal fabrication shops, and field maintenance work. The regular spiral flute geometry handles general-purpose through-hole and blind-hole drilling efficiently. The two-flute design promotes chip evacuation in both ferrous and non-ferrous materials. This bit is part of OSG Series 1600, a high-performance jobber-length line intended for production use where dimensional accuracy and coating durability are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium High Speed Steel construction for heat resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eTitanium Nitride (TiN) coating reduces friction and extends tool life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003e130-degree S-thinned split point for self-centering and reduced thrust on steel and stainless\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web for consistent chip evacuation in blind and cross-hole drilling\u003c\/li\u003e\n\u003cli\u003e4 mm straight-cylindrical shank fits standard drill chucks and collet-style toolholders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.018 mm for close-tolerance hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Part of OSG Series 1600, sized within the 3.00 to 4.00 mm jobber drill range. Compatible with any standard drill chuck or collet accepting a 4 mm straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only with the drilling machine powered off and, for CNC applications, in a safe, locked-out state. Secure the shank fully in the chuck or collet to the recommended grip depth before operation. Inspect the cutting edges and TiN coating for wear or chipping before each use, as a damaged edge will affect hole tolerance and surface finish. Coolant-through is not supported on this bit; apply external cutting fluid as appropriate for the workpiece material and feed rate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.5 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 71 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 39 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm 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 split point\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\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: 0.025 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: 62535\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728405889330,"sku":"62535","price":36.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_9ca423d5-e0a2-46b9-8e91-490587cbebee.jpg?v=1788690904","url":"https:\/\/voomisupply.com\/products\/osg-62535-jobber-drill-bit-3-5-mm-tin-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
