It is sized to wire gauge 50, equivalent to 0.0700 inches in diameter, with a 135-degree split-point geometry that reduces walking on contact and lowers thrust requirements. The 2-inch overall length and straight cylindrical shank make it compatible with standard drill chucks across a wide range of equipment. A two-flute, spiral regular configuration clears chips efficiently, and the oxide bronze finish adds a layer of surface protection during extended use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling through steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering workpiece material codes P, M, K, N, and S under NAS 907 classification. It is a general-purpose tool appropriate for precision production drilling, maintenance and repair operations, and fabrication work where small-diameter, tight-tolerance holes are required. The 7xD flute-to-diameter ratio supports maximum drilling depth of 0.5 inches. Machinists, millwrights, and maintenance technicians in industrial facilities are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge 50 diameter, 0.0700 inches, for tight-tolerance small-hole applications\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walk and lowers required drilling pressure\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eOxide bronze finish provides surface protection during use\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration for improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose jobber-length drill bit for use in standard straight-shank drill chucks across handheld, bench, and machine-mounted drilling equipment compatible with 0.0700-inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit should be installed by machinists or qualified maintenance technicians familiar with small-diameter tooling. Ensure the drill chuck is fully tightened and the shank is seated completely before operation to prevent slippage. At this diameter, bit breakage risk increases with excessive feed pressure or lateral loading, so controlled, steady feed rates are essential. Disconnect or de-energize all equipment 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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0700 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (Cobalt)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\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: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys, Titanium\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: R88CO-R89CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999977\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691444338994,"sku":"5999977","price":62.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e3d535a3d9bbc988b898b8040095a33_eb0b407f-139f-48d9-afe8-aceefaf6a4fa.jpg?v=1788285116","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999977-cobalt-jobber-drill-bit-50","provider":"Voomi Supply","version":"1.0","type":"link"}
