Built from cobalt high speed steel with a coated finish, this bit resists heat and wear during demanding production drilling. It features a 130-degree drill point angle, a standard point type with R-thinned web, and a regular spiral flute geometry that promotes efficient chip evacuation. At 0.177 inches (wire size 16, 4.50 mm) in diameter with a 2-9\/16-inch overall length, this stub-length drill is suited for shop environments where rigidity and accuracy are priorities. It is installed and used by machinists, tool-and-die professionals, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC drilling, and general-purpose metalworking where shorter flute length provides added rigidity. Its cobalt high speed steel construction makes it well-suited for drilling steel, alloy steel, and other ferrous materials at elevated cutting speeds. The straight-cylindrical shank provides positive seating in standard drill chucks and collet holders. The screw machine length format fits applications where drill press clearance is limited or where a shorter tool length reduces deflection in precision work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for enhanced heat and wear resistance in ferrous metal drilling\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with R-thinned web for improved centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length format at 2-9\/16 inches overall for added rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral configuration promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for consistent, accurate hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for screw machine and general metalworking applications involving steel and alloy steel workpieces.

Ensure the drill press, lathe, or CNC machine is fully powered down and locked out before changing tooling. Secure the straight-cylindrical shank firmly in the chuck or collet to the manufacturer-specified seating depth before operation. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.177 inches (Wire Size 16, 4.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\u003eTool Material\u003c\/strong\u003e: Cobalt 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\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: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 10177005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730552521010,"sku":"10177005","price":42.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fb6351385c1247f184a3cca1efdd118.jpg?v=1788719470","url":"https:\/\/voomisupply.com\/products\/osg-10177005-screw-machine-drill-bit-0-177-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
