At 0.70 mm in diameter (0.0276 inch), it is built for precision drilling in tight clearance applications where stub-length rigidity reduces deflection and runout. The 150-degree, 4-facet point geometry provides self-centering entry and reduces thrust load on entry, making it well suited for production and repair work in steel, stainless steel, aluminum, and other non-ferrous materials. Overall length is 38.00 mm (1.4961 inch) with a 4.50 mm flute length and a 3.00 mm straight shank (0.1181 inch).\u003c\/p\u003e\n\u003cp\u003eThis bit belongs to the OSG Series 1100 line, a high-performance screw machine length family designed for close-tolerance work in CNC machining centers, drill presses, and benchtop applications. The stub-length format and web-thinned, tapered-web construction make this bit a practical choice for machinists, tool-and-die shops, precision fabricators, and maintenance technicians drilling small-diameter holes in hard or abrasive workpiece materials. Primary workpiece materials include carbon steel, stainless steel, aluminum, and general non-ferrous alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVanadium high-speed steel construction for elevated hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e150-degree, 4-facet point geometry for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered-web design lowers cutting resistance at the chisel edge\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity and minimizes deflection at small diameters\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute promotes consistent chip evacuation in through-hole and blind-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks and collet systems accepting a 3.00 mm (0.1181 inch) shank. Suitable for drilling steel, stainless steel, aluminum, and non-ferrous alloys as an OEM-style production or replacement drill bit in Series 1100 applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight shank in a properly sized drill chuck or collet to minimize runout before use. At 0.70 mm diameter, low spindle runout and a rigid setup are critical to prevent breakage — verify chuck condition and concentricity before starting. Apply cutting fluid or mist coolant appropriate for the workpiece material to manage heat at this small diameter. Inspect the cutting edges for wear or chipping before each use, as TiN-coated bits at sub-1 mm diameters are sensitive to re-striking a hardened or work-hardened surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.70 mm (0.0276 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm (1.4961 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 4 Facet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.012 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749552783666,"sku":"61507","price":48.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2882ef1fe598206ec666eb082076d472_4503a04b-957f-42c8-92f5-8947fdfded8d.jpg?v=1788907516","url":"https:\/\/voomisupply.com\/products\/osg-61507-screw-machine-drill-bit-0-70-mm-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
