It measures 0.016 inches in diameter, corresponding to wire gauge size 78, and features a 118-degree standard point angle suited for drilling into cast iron and steel. The bit is manufactured from high speed steel with an oxide finish that provides basic surface protection. The straight-cylindrical shank seats in standard drill chucks without modification. Machinists, maintenance technicians, and fabricators use this bit for small-diameter through-hole work on the bench or at the machine.\u003c\/p\u003e\u003cp\u003eThis bit belongs to the PRECISION TWIST DRILL Series R18, a general-purpose line built to ANSI standards. It is intended for drilling cast iron and steel in light production, maintenance, and repair environments. The 7\/8-inch overall length and 3\/16-inch flute length make it appropriate for shallow-hole applications where a compact tool is needed. Right-hand spiral flutes evacuate chips efficiently during drilling. Coolant-through is not supported on this bit, so conventional flood or mist cooling is applied externally when required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 78 diameter at 0.016 inches for precise small-diameter hole work\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for use in cast iron and steel\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish surface treatment\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces thrust and improves cut initiation\u003c\/li\u003e\n\u003cli\u003eBuilt to ANSI standards as part of the Series R18 general-purpose line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose jobber drill bit for use in standard drill chucks accepting straight-cylindrical shanks, suitable for bench drills, drill presses, and hand-held power drills used in metalworking and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or maintenance technician into a standard keyless or keyed drill chuck. Secure the straight-cylindrical shank fully in the chuck jaws before drilling. Always power down or de-energize the drill press or machine tool before changing bits. At 0.016 inches diameter, this bit is fragile -- use low feed pressure and appropriate spindle speed for the workpiece material to avoid breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 78\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0160 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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694294696242,"sku":"5999189","price":51.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdcfcb1fbe391974da2a4bcf16cedcb2.jpg?v=1788322741","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999189-jobber-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
