Built from vanadium high speed steel with a titanium nitride (TiN) coating, the bit delivers extended tool life and reduced friction during cutting. It measures 4.55 mm in diameter with a 91 mm overall length and a 47 mm flute length. The 120-degree split point geometry includes S-thinned web thinning for self-centering capability and reduced thrust force. A straight-cylindrical shank at 6.00 mm diameter fits standard drill chucks. Machinists, maintenance mechanics, and metal fabricators typically use this bit for production and repair drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling into steel, stainless steel, aluminum, aluminum alloys, and aluminum silicate. Typical applications include blind hole drilling, cross hole drilling, and self-centering operations in both manual and CNC setups. The regular spiral flute design promotes efficient chip evacuation in these materials. The 4.55 mm diameter falls within the 4.00 to 5.00 mm size range of the OSG Series 1600 jobber drill line, which targets high-performance general-purpose metal drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high speed steel construction for toughness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003eS-thinned 120-degree split point promotes self-centering and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration for consistent chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute geometry suited for standard drilling operations\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — compatible with dry or flood external coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance jobber-length drill bit for use in steel, stainless steel, aluminum, and aluminum alloy workpieces as part of the OSG Series 1600 product line.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists and metalworkers in standard drill chucks or CNC tool holders accepting a 6.00 mm straight-cylindrical shank. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Always wear appropriate eye protection and follow shop safety procedures when drilling metal. Do not exceed the recommended feed and speed range for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.55 mm (0.1791 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm (3.583 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm (1.85 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\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\u003eWeb Thinning\u003c\/strong\u003e: S-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eSeries\u003c\/strong\u003e: 1600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 8597455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731059638578,"sku":"8597455","price":64.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e423ce07c9d4a94e93058857fc46990_6acea6ec-70ff-42f3-b702-e9eb69053984.jpg?v=1788726396","url":"https:\/\/voomisupply.com\/products\/osg-8597455-jobber-drill-bit-4-55mm-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
