It measures 27\/64 inch (0.4219 inches) in diameter with a 118-degree standard point angle and a steam oxide coating that provides mild lubricity and corrosion resistance during storage and cutting. The 2-flute spiral design with a regular helix and tapered web configuration evacuates chips efficiently on through-hole and blind-hole operations. The straight cylindrical shank seats directly in standard drill chucks. This bit is part of the Series R10A-R15A-R18A product family and conforms to ANSI and NAS 907 standards.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field environments. The 5.375-inch overall length and 3.9375-inch flute length support drilling depths up to 3-15\/16 inches, making it appropriate for structural, fabrication, and maintenance drilling tasks. Licensed trades including HVAC, plumbing, and electrical contractors frequently use jobber-length HSS bits for metal panel, bracket, and conduit work. The 27\/64-inch diameter is commonly used as a tap-drill size and for clearance holes in light structural applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27\/64 inch diameter with matching 0.4219-inch straight cylindrical shank for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose metal drilling across multiple material types\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating for mild lubricity and in-storage corrosion protection\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral with tapered, web-thinned construction for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eFlute-to-diameter ratio of 9xD supports drilling to 3-15\/16 inches maximum depth\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and NAS 907 specifications for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces (workpiece material codes P, M, K, N, S).

Secure the workpiece before drilling and use cutting fluid when working with stainless steel or titanium to extend tool life. Inspect the cutting edges before each use and replace the bit if the point shows chipping or excessive wear. No special tools are required for chuck installation beyond the chuck key or tightening collar supplied with the drill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 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: 5.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.9375 inches (3-15\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4219 inches (27\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches (1-7\/16 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\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\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10A-R15A-R18A\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\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 5997552\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698296357170,"sku":"5997552","price":103.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bd2688cd1a12148f47280ccafeb14f2_c2a6d8a6-0c98-41b8-acb0-19ede76c825a.jpg?v=1788360706","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997552-jobber-drill-bit-27-64","provider":"Voomi Supply","version":"1.0","type":"link"}
