At 0.0120 inches in diameter and 0.75 inches overall length, it is engineered for precision drilling in tight tolerances where small-diameter holes are required. The 118-degree standard point angle and web-thinned, tapered web construction reduce thrust and improve chip evacuation. Two regular spiral flutes clear material efficiently over a flute length of 0.0938 inches. This bit is a general-purpose tool used by machinists, tool-and-die workers, and field technicians who need reliable small-hole performance across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe 5999247 is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. Its straight-cylindrical shank at 0.0120 inches diameter fits standard collets and chucks accepting small-diameter tooling. The 8xD flute-to-diameter ratio and maximum drilling depth of 0.0938 inches make it appropriate for shallow, precise holes in production machining, repair work, and fabrication environments where wire-gauge sizing is specified. The Series R10P-R15P-R18P designation identifies it within PRECISION TWIST DRILL jobber-length product families designed to ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 83 (0.0120 inches) for precision small-diameter drilling applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose use without coolant-through requirement\u003c\/li\u003e\n  \u003cli\u003eTwo regular spiral flutes with right-hand cutting direction for conventional drill press and CNC use\u003c\/li\u003e\n  \u003cli\u003eManufactured to ANSI standards within Series R10P-R15P-R18P\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 fitting any standard small-diameter collet or drill chuck that accepts a 0.0120-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists and maintenance technicians should secure the straight-cylindrical shank firmly in a calibrated collet or Jacobs-style chuck before operation. Confirm spindle speed is appropriate for the workpiece material and bit diameter per standard speeds-and-feeds references, as small-diameter bits are susceptible to breakage from excessive feed pressure. No coolant-through capability is present; apply cutting fluid externally when drilling harder alloys or stainless steel. Inspect the cutting edges before each use and discard bent or chipped bits to prevent workpiece damage or injury.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 83\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.6562 inches (21\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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: R10P-R15P-R18P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5999247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51703393452338,"sku":"5999247","price":128.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a9595767adf1a1bebcf3507a2874d00_b707b800-965c-41c8-a667-3186d0f4074a.jpg?v=1788416432","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999247-jobber-drill-bit-83-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
