Built from high speed steel with a coated finish, it features a 0.072-inch (1.83 mm) diameter, a 140-degree faceted drill point, and a web-thinned tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 3.00 mm in diameter and accepts standard chucks without modification. This bit suits production drilling environments where a shorter-than-jobber-length tool improves rigidity and precision. Typical installers and users include machinists, tool-and-die technicians, and maintenance professionals working on close-tolerance bore applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length profile provides greater stiffness than standard jobber-length bits, making it a practical choice for CNC drilling centers, turret lathes, and manual drill presses where short-reach rigidity matters. The 2-flute spiral design promotes consistent chip clearance throughout the cut. OSG Series 1100 bits in this diameter range are commonly selected for small-bore work in light manufacturing and precision repair applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.072-inch (1.83 mm) drill diameter with a tolerance of +0 to -0.014 mm for close-tolerance bore work\u003c\/li\u003e\n\u003cli\u003e140-degree faceted drill point reduces walking and improves centering on hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust force and extends tool life in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for improved surface hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eScrew machine length (overall length 43.00 mm) delivers added rigidity over standard jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute regular spiral design promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eOSG Series 1100 screw machine length drill bit rated for use in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces.

Secure the straight-cylindrical shank firmly in a compatible chuck before operation and verify runout is within acceptable limits for the application. Do not exceed the rated speed range for the workpiece material and bit diameter. Coolant-through is not supported on this bit; use appropriate external cutting fluid when drilling steel or stainless steel to manage heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.072 inches (1.83 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 43.00 mm (approximately 1.693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11.00 mm (approximately 0.433 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.014 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\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 8595183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754871587122,"sku":"8595183","price":41.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b29e666e1a3ea93eddc467d7cf1048fd.jpg?v=1788949412","url":"https:\/\/voomisupply.com\/products\/osg-8595183-screw-machine-drill-bit-0-072in-hss-140deg","provider":"Voomi Supply","version":"1.0","type":"link"}
