Designed for high-precision drilling in short, rigid setups, this bit features a 135-degree split point that self-centers on entry and reduces walking without a center punch. The bright, uncoated finish is suitable for general-purpose drilling in a wide range of materials. At 1.5 inches overall length with a 0.4375-inch flute length, this is a stub-length geometry built for rigidity and accuracy. Installation is performed by machinists and tool-and-die professionals using CNC or manual drill presses and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited for precision drilling in metal fabrication, light manufacturing, and machine shop environments. The screw machine length format keeps the bit short and stiff, reducing deflection in close-tolerance work. It is appropriate for use in ferrous and non-ferrous materials where a small-diameter, carbide-grade cutting tool is required. The straight cylindrical shank fits standard collets and drill chucks sized for this diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and wear resistance in demanding drilling applications\u003c\/li\u003e\n  \u003cli\u003e135-degree split point promotes self-centering and reduces thrust on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length geometry minimizes deflection for tighter tolerances\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a broad range of work materials and cutting fluids\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral fluting for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide drill bit for applications requiring a wire gauge No. 51 diameter in screw machine length format with a straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists and precision drilling professionals in CNC machining centers, drill presses, or manual mills with appropriate collet or chuck tooling. Ensure the machine spindle and chuck are clean and free of runout before seating the straight shank. Carbide tooling is brittle and should not be subjected to side-loading or interrupted cuts without confirming the setup is rigid and square. Always power down and lock out the machine before changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 1.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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: Regular Spiral\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC20251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51750154535218,"sku":"TC20251","price":25.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edf2575ef597bb8f9d8401683cfc1a0a_f3d29899-6e4b-4e89-9d87-15c268c904c4.jpg?v=1788913889","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc20251-screw-machine-drill-bit-size-51-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
