Built from high speed steel (HSS) with a steam oxide coating, this bit handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It carries a standard 118-degree point angle with a web-thinned, tapered web configuration that reduces thrust and improves centering. The straight-cylindrical shank measures 0.1495 inches in diameter, matching the wire gauge size 25 drill diameter. Two spiral flutes in a regular spiral pattern clear chips efficiently during drilling. Overall length is 3 inches with a flute length of 1.875 inches.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in metal fabrication, mechanical contracting, and industrial service work. The R18A series designation places it within a proven jobber-length line built to ANSI standards and NAS 907 specification. With a 13xD flute-to-diameter ratio and a maximum drilling depth of 1.875 inches, it fits standard drill chucks used by machinists, pipefitters, electricians, and general tradespeople. Right-hand cut geometry is compatible with conventional drill presses, hand drills, and CNC equipment. No coolant-through capability; suitable for use with external cutting fluid where required by the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 25 — 0.1495 inch decimal diameter\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating provides mild lubricity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards and NAS 907 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks accepting a 0.1495-inch straight-cylindrical shank, for use on drill presses, hand drills, and compatible CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight-cylindrical shank fully in the chuck and verify zero runout before starting the cut. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to prevent work hardening and premature bit wear. Operate at a spindle speed appropriate for the workpiece material and drill diameter — higher speeds suit non-ferrous metals, lower speeds suit hardened steels. Inspect the cutting edges for wear before each use; a dull bit generates excess heat and reduces hole quality.\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: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1495 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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 13xD\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0083 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: 5999343\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692707414322,"sku":"5999343","price":49.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb0d3aa62b12a911c87b71fb6c8893a6_a1ece31e-6891-4e54-9afa-0d9a0c06fd83.jpg?v=1788301536","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999343-jobber-drill-bit-25-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
