Built from high speed steel with a titanium nitride (TiN) coating, it measures 0.1811 inches (4.60 mm) in diameter with an overall length of 2.677 inches (68.00 mm). The 120-degree faceted point and fast spiral flute geometry promote efficient chip evacuation and accurate entry. A web-thinned, parallel web construction reduces thrust force at the cutting edge. This bit is suited for production drilling environments where cycle times and tool life are critical concerns for machinists and tool crib personnel.\u003c\/p\u003e\u003cp\u003eThe OSG 61546 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length profile  -  shorter overall than jobber-length bits  -  provides added rigidity in turret lathes, CNC machining centers, screw machines, and other production drilling setups where chatter and deflection must be minimized. The straight-cylindrical shank fits standard drill chucks and collet systems sized for the 0.2362-inch (6.00 mm) shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e120-degree faceted point for accurate self-centering and clean entry\u003c\/li\u003e\n\u003cli\u003eFast spiral flute promotes aggressive chip evacuation in deeper holes\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces drilling thrust and cutting forces\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity over standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for use with conventional clockwise-rotating spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate.

Secure the shank fully in the chuck or collet before operating the spindle. Verify spindle speed and feed rate are appropriate for the workpiece material and hole diameter before beginning the cut. Do not exceed the bit's rated material applications, and inspect the cutting edges for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1811 inches (4.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.677 inches (68.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.945 inches (24.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 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\u003ePoint Type\u003c\/strong\u003e: Faceted\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: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 61546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743087493426,"sku":"61546","price":59.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73cffd66c1a5f88c5d3d1a65ecc35743.jpg?v=1788842508","url":"https:\/\/voomisupply.com\/products\/osg-61546-screw-machine-drill-bit-0-1811-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
