It is manufactured from high speed steel (HSS) with a bright uncoated finish and features a standard 118-degree split-point angle with web thinning for improved centering and reduced feed pressure. The straight-cylindrical shank and regular spiral flute geometry make this bit compatible with standard drill chucks. At 1.5 inches overall length with a 0.625-inch flute length, this compact bit is suited for precision drilling in tight clearance applications. It is typically installed by machinists, toolroom technicians, and mechanical contractors working on close-tolerance assemblies.\u003c\/p\u003e\u003cp\u003eThis bit is designed for drilling in steel, cast iron, non-ferrous metals, superalloys, and titanium. It is well suited for light-duty production drilling, maintenance and repair operations, and prototype fabrication where small-diameter precision holes are required. The 17xD flute-to-diameter ratio supports chip evacuation in deeper passes relative to the bit diameter. The tapered web configuration and web-thinned point reduce walking and improve bite at entry, which is particularly useful when drilling harder ferrous materials without a center punch.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 63 with 0.0370-inch diameter for precision small-hole drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for use in steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e118-degree standard drill point angle with web-thinned, tapered web for improved centering\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; no coolant-through requirement for general-purpose use\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; Series R10H-R18H general purpose designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks and drill presses handling wire-gauge tooling.

Secure the straight-cylindrical shank fully in a properly sized drill chuck before operation, and verify chuck runout is within tolerance for small-diameter tooling of this size. Reduce spindle speed and increase feed rate gradually when transitioning to harder workpiece materials such as superalloys or titanium. Inspect the cutting edges for wear before each use, as small-diameter HSS bits are susceptible to breakage if run at excessive speed or with side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 63\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0370 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\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\u003eFlute Length\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0370 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 17xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\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: R10H-R18H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 5998075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701059420466,"sku":"5998075","price":56.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4691d72f892b92915254364cb4aea851_2bb1d5da-06a7-4c0b-a2ad-fcaf9fe4af55.jpg?v=1788397610","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998075-wire-63-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
