Built from high speed steel (HSS) with a coated finish, this bit features a 0.5 inch (12.70 mm) diameter, a 120-degree faceted drill point, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 12.00 mm in diameter, and the overall length comes in at 108.00 mm (approximately 4.25 inches). Two spiral flutes with a regular spiral type handle chip removal efficiently during operation. Licensed machinists and metalworking professionals install this bit in screw machine and production drilling setups.\u003c\/p\u003e\u003cp\u003eThe OSG 61627 Series 1100 is suited for production and job-shop environments where shorter drill length improves rigidity and reduces deflection. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length profile makes it a standard choice for drill presses, CNC machining centers, and turret lathes where stub-length tooling is preferred for accuracy and stability. The 5xD flute-to-diameter ratio supports controlled chip flow across a range of feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 inch (12.70 mm) diameter with a diameter tolerance of +0 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e120-degree faceted drill point with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003e2 spiral flutes, regular spiral type, with 51.00 mm flute length\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, aluminum, and aluminum alloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw machine length drilling applications on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the straight-cylindrical shank firmly in a compatible chuck before operation, and verify that chuck and spindle capacities match the 0.5 inch shank diameter. Always power down and lock out the machine before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 108.00 mm (approximately 4.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 51.00 mm (approximately 2.0 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.027 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\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: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.165 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: 61627\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730712789298,"sku":"61627","price":216.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/135da11d122ae9bc9e1183a5562893b9.jpg?v=1788721668","url":"https:\/\/voomisupply.com\/products\/osg-61627-screw-machine-drill-bit-0-5-in-hss-120-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
