Built from high speed steel with a coated finish, this bit features a 120-degree faceted point and a web-thinned, tapered web construction that reduces entry force and improves centering. At 0.4134 inches (10.50 mm) in diameter, it runs a right-hand spiral flute pattern with a 2-flute configuration. The shorter screw machine length body provides added rigidity compared to jobber-length bits, making it well suited for drilling in tight spaces and on production machines where runout and deflection must be minimized.\u003c\/p\u003e\n\u003cp\u003eThe OSG 61605 is intended for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. It is a practical choice for machinists, tool-and-die technicians, and maintenance mechanics running drill presses, CNC machining centers, turret lathes, or manual production equipment. The screw machine length format fits standard drill chucks and collet holders accepting a 12.00 mm (approximately 0.4724 inches) straight cylindrical shank. It is rated as a high-performance grade bit, appropriate for production drilling cycles where tool life and dimensional consistency matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance and heat management\u003c\/li\u003e\n  \u003cli\u003e120-degree faceted drill point for accurate self-centering on flat and curved metal surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust force and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral design with spiral flute geometry optimized for Series 1100 performance standards\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (100.00 mm overall, approximately 3.937 inches) provides greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0 to minus 0.027 mm ensures consistent hole sizing within tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, CNC machining centers, turret lathes, and other equipment accepting a straight cylindrical shank. Suitable for workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate.

Secure the straight cylindrical shank fully in the chuck or collet before operation and verify runout with a dial indicator if tight tolerances are required. Do not exceed the spindle speed and feed rate recommendations appropriate for the workpiece material and bit diameter. Inspect the cutting edges and coating condition before each use and replace the bit if chipping, excessive wear, or dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4134 inches (10.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100.00 mm (approximately 3.937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm (approximately 1.693 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm (approximately 0.4724 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\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-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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: Plus 0 to minus 0.027 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 61605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727466168626,"sku":"61605","price":121.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09a024802abebc8d139ef1d964a60b60.jpg?v=1788678233","url":"https:\/\/voomisupply.com\/products\/osg-61605-screw-machine-drill-bit-0-4134-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
