Built from high speed steel with a bright uncoated finish, this bit features a standard 118-degree split point, a two-flute regular spiral design, and a web-thinned tapered web for reduced thrust during entry. The straight-cylindrical shank seats directly in standard drill chucks without adapters. At 1.5 inches overall length with a 5\/8-inch flute length, this bit is sized for precision small-hole work in tight or shallow applications. It is part of the R18P series and conforms to ANSI standards.\u003c\/p\u003e\u003cp\u003eThis bit is designed for general-purpose drilling in a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is well suited for light-duty production drilling, maintenance and repair, and prototype work where accurate small-diameter holes are required. The right-hand cut and spiral flute geometry support clean chip evacuation in both handheld and drill-press setups. Coolant-through capability is not available on this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 63 sizing at 0.0370 inches decimal diameter for precise small-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tapered web reduces entry thrust\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — suitable for general-purpose use without heat-treatment concerns\u003c\/li\u003e\n\u003cli\u003e5\/8-inch maximum drilling depth supports shallow-bore work in thin stock\u003c\/li\u003e\n\u003cli\u003eANSI-compliant jobber-length geometry for consistent fitment in standard chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard drill chucks accepting a 0.0370-inch straight-cylindrical shank.

Secure the straight-cylindrical shank fully in a properly sized drill chuck before operation to prevent runout or bit breakage. Small-diameter bits are susceptible to breakage under side loading or excessive feed pressure — use consistent, controlled feed rates. Follow applicable shop safety practices and wear appropriate eye protection during all drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 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\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\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 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\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\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\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 17xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\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\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: 5999145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51700131397938,"sku":"5999145","price":41.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a9595767adf1a1bebcf3507a2874d00_4699baa4-b2fe-4139-b649-d881c2439ec5.jpg?v=1788386445","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999145-jobber-drill-bit-no-63-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
