It measures 0.0370 inches in diameter and carries a 135-degree split-point geometry with web thinning to reduce walking and lower thrust at entry. The straw oxide finish provides mild lubricity and heat resistance during operation. At 1.5 inches overall length with a 0.625-inch flute length, this is a compact, short-reach bit suited for tight-clearance drilling in production or maintenance applications. It is rated heavy duty and meets ANSI and NAS 907 specifications.\u003c\/p\u003e\u003cp\u003eThis bit is built for general-purpose drilling in steel and a broad range of workpiece materials including cast iron, non-ferrous metals, and high-temp alloys, corresponding to material codes P, M, K, N, and S. It fits standard drill chucks accepting a 0.0370-inch straight cylindrical shank. Typical users include machinists, maintenance technicians, and fabricators working with precision wire-gauge hole requirements. The bit is sold individually but requires a minimum order of 12 units per the manufacturer packaging structure. It belongs to the R10CO-R15CO-R18CO series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e135-degree standard point with web thinning reduces thrust and self-centers on entry\u003c\/li\u003e\n\u003cli\u003eStraw oxide coating provides surface lubricity and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web configuration promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard keyed and keyless drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 standards for heavy-duty jobber drill applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose replacement or production drill bit for applications requiring a wire gauge size 63 (0.0370-inch diameter) hole.

Secure the shank fully in the chuck and verify runout before drilling. Ensure the workpiece is clamped firmly to prevent movement during operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not have a coolant-through design.\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: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 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\u003eShank Diameter\u003c\/strong\u003e: 0.0370 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 17xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Material Codes P, M, K, N, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 5997783\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51715856597298,"sku":"5997783","price":75.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_50d19f52-cbc1-4e81-9c06-fcd550601030.jpg?v=1788519088","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997783-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
