Built from cobalt high speed steel and coated with titanium nitride (TiN), this bit delivers increased wear resistance and heat tolerance compared to standard HSS tooling. It features a 130-degree point angle with X-thinned web geometry, which reduces thrust force on entry and improves hole accuracy. The straight-cylindrical shank measures 0.1875 inches in diameter, and the overall length is 2-7\/16 inches, making it compact enough for tight-clearance drilling setups. Machinists, tool-and-die shops, and production drilling operations are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized to wire gauge number 23, corresponding to 0.1540 inches (3.91 mm) in decimal and metric equivalents. The screw machine length format — shorter than jobber length — reduces deflection and improves rigidity during high-cycle production drilling. With a 3xD flute-to-diameter ratio and a 1-inch flute length, this bit is suited for shallow-to-moderate depth holes in ferrous materials. It is part of OSG Series 1000 and is classified as a high-performance grade drill. Applications include CNC machining centers, drill presses, and manual turret lathes working with mild steel, alloy steel, and similar ferrous stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with X-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine length body minimizes deflection in production drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral and straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement or production drill for applications requiring wire size 23 (0.1540 inches) hole diameters in steel and alloy steel workpieces. Compatible with standard straight-shank drill chucks accepting a 0.1875-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed by machinists and tool operators into a compatible drill chuck or collet on a CNC machining center, drill press, or lathe turret. Secure the shank fully in the chuck and verify runout before beginning production runs. Always set appropriate spindle speed and feed rate for the workpiece material and bit diameter to avoid premature wear or breakage. Coolant or cutting oil is recommended for extended-run drilling in steel, even though this bit does not feature through-coolant capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1540 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 3.91 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches (61.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch (25.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, X-Thinned\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\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -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: 10154005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738747765042,"sku":"10154005","price":42.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/529a02c582e209cb7c5c63bbeebbad14_618ca869-8592-4b7d-b5b3-b69a32aa9826.jpg?v=1788803799","url":"https:\/\/voomisupply.com\/products\/osg-10154005-screw-machine-drill-bit-wire-23-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
