It carries a 118-degree standard point angle and a right-hand spiral flute with a regular helix, making it a general-purpose drilling tool suited for production and maintenance environments. The bit measures 0.75 inches overall length with a 0.125-inch flute length and a straight-cylindrical shank diameter of 0.0145 inches. The web is thinned and tapered, reducing entry resistance in harder stock. Machinists, tool-and-die techs, and maintenance technicians reach for this bit when precision micro-drilling is required.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits applications where a wire gauge number 79 hole diameter of 0.0145 inches is specified, including instrument work, electronics chassis, jig fixtures, and precision mechanical assemblies. The ANSI-standard geometry and R18P series designation place it in a well-established size family used across general manufacturing and maintenance shops. Coolant-through capability is not included, so external flood or mist cooling is recommended when drilling heat-sensitive materials or running extended cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 79 with 0.0145-inch decimal diameter for precision micro-hole applications\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes consistent chip evacuation in shallow holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without special adapters\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant geometry in the R10P-R15P-R18P series for predictable, repeatable performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style jobber drill bit in wire gauge size 79, compatible with any standard drill chuck or collet sized to accept a 0.0145-inch straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits, as small-diameter bits are sensitive to misalignment and deflection. Power down and de-energize the spindle completely before changing tooling. Avoid side-loading or prying with the bit, as the small shank diameter is susceptible to breakage under lateral force.\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: 79\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0145 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: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0145 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.625 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: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\u003eStandard\u003c\/strong\u003e: ANSI\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: 5999223\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692361842994,"sku":"5999223","price":66.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a9595767adf1a1bebcf3507a2874d00_020b8c4e-57b6-4932-85aa-c88d355bd185.jpg?v=1788296773","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999223-wire-79-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
