The bit is machined from high speed steel and finished with a steam oxide coating that reduces friction and helps resist heat buildup during operation. It cuts in a right-hand direction with a standard 118-degree point angle, a regular spiral flute, and a web-thinned tip that reduces thrust at entry. Overall length is 1.125 inches with a straight-cylindrical shank diameter of 0.0250 inches. Licensed tradespeople and precision machinists reach for this size when drilling tight-tolerance holes in steel, cast iron, and non-ferrous alloys.\u003c\/p\u003e\u003cp\u003eThis bit fits applications where a 0.0250-inch diameter hole is required, including pilot holes, jig work, and fine metalwork in both shop and field environments. Its compact jobber length and 5\/16-inch flute length make it practical for benchtop drill presses, CNC equipment, and hand-held drill drivers when clearance is limited. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. The R18 series designation indicates this bit meets ANSI standards for dimensional consistency across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 72, decimal equivalent 0.0250 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with steam oxide coating for heat and friction resistance\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design with a 5\/16-inch maximum drilling depth\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; Series R10-R15-R18 designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber length replacement or production drill bit for use in any standard drill chuck or collet accepting a 0.0250-inch straight-cylindrical shank.

Secure the shank fully in the chuck before operation and confirm the cutting speed is appropriate for the workpiece material and bit diameter. At this small diameter, use light feed pressure to prevent bit deflection or breakage. Always wear appropriate eye protection and follow applicable shop safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 72\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0250 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\u003eDrill Bit Material\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.125 inches (1-1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.8125 inches (13\/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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5999178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698801541426,"sku":"5999178","price":54.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2bbd17554f8298fe95bb319a732ccea_b0ffb15f-a9bc-4870-b4ee-e985a97e0028.jpg?v=1788368152","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999178-wire-72-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
