Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction in demanding production environments. It carries a wire gauge size of 21, which corresponds to 0.1591 inches (4.04 mm) in decimal form. The 120-degree split point with S-thinned web promotes self-centering entry and reduces thrust force, making it well suited for work on steel, stainless steel, aluminum, and aluminum alloys. A licensed machinist or tool-and-die technician would typically deploy this bit in CNC or manual drilling operations requiring tight-tolerance hole placement.\u003c\/p\u003e\u003cp\u003eThis bit fits production machining, fabrication, and maintenance applications where wire-gauge sizing is specified. It is appropriate for blind holes, cross holes, through-hole drilling, and self-centering operations. The Series 1600 designation places it in OSG's high-performance jobber-length line. The straight-cylindrical shank with a 6.00 mm shank diameter seats in standard drill chucks and collet holders used in both benchtop and CNC setups. Workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate, covering a broad range of shop and field machining tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 21 (0.1591 inch \/ 4.04 mm) with diameter tolerance of plus 0 to minus 0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eVanadium high speed steel construction rated for high-performance cutting in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends tool life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003e120-degree drill point with S-thinned web for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry with 2 flutes and 43.00 mm flute length promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length drill bit for use in standard drill chucks and collet holders accepting a 6.00 mm straight-cylindrical shank. Suitable for CNC machining centers, drill presses, and hand-held power drills where wire-gauge or decimal-inch sizing in the 0.1500 to 0.2000 inch range is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and powered down before inserting or removing the bit from the chuck or collet. Verify chuck or collet bore matches the 6.00 mm shank diameter to prevent runout. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling stainless steel or other work-hardening materials to manage heat buildup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1591 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.04 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 87.00 mm (approximately 3.43 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm (approximately 1.69 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 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\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: 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\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\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: 8597404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733108818226,"sku":"8597404","price":58.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f3d3ca60b00d63707f713aba940e093.jpg?v=1788751480","url":"https:\/\/voomisupply.com\/products\/osg-8597404-jobber-drill-bit-21-wire-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
