Manufactured from high speed steel with a steam oxide coating, this bit handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It carries a wire size designation of 13, corresponding to a decimal diameter of 0.185 inches. The 118-degree standard point angle and web-thinned, tapered web construction promote clean entry and reduced thrust. Overall length is 3.5 inches with a 2.3125-inch flute length and a straight-cylindrical shank. Licensed HVAC techs, machinists, plumbers, and electricians alike reach for bits like this when drilling pilot, clearance, or tap-prep holes in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited for production and maintenance drilling in residential and commercial trade environments. The Series R18 designation places it within the R10-R15-R18 family, built to ANSI standards for consistent geometry and interchangeability. The two-spiral flutes in a regular helix promote chip evacuation during drilling, making the bit reliable for through-hole and blind-hole work in metal fabrication, HVAC equipment installation, electrical panel work, and plumbing rough-in tasks where precise hole sizing is required. Flute-by-diameter ratio is 13xD, offering good reach relative to bit diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 13 (0.185 inch decimal diameter) straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with steam oxide coating for corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes in regular helix pattern promote efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with 2.3125-inch maximum drilling depth\u003c\/li\u003e\n  \u003cli\u003eBuilt to ANSI standards; Series R10-R15-R18 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium.

Secure the workpiece before drilling to prevent rotation and ensure consistent hole geometry. Use cutting fluid or coolant on harder materials such as stainless steel and titanium to manage heat buildup, even though coolant-through is not available on this bit. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to maintain hole accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.185 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: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches (2-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches (1-3\/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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; Non-Ferrous Metal; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 13xD\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\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5998297\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702463660338,"sku":"5998297","price":55.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2bbd17554f8298fe95bb319a732ccea_419e226b-2f0e-498f-b166-42d974ba460a.jpg?v=1788411051","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998297-jobber-drill-bit-13-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
