It is designed for general-purpose drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The two-flute spiral design with a tapered, web-thinned web promotes chip evacuation and reduces thrust during entry. The straight-cylindrical shank seats securely in standard drill chucks. This bit is manufactured to ANSI standards and belongs to the R10P-R15P-R18P series, making it a reliable option for machinists, maintenance technicians, pipefitters, and other trade professionals who require consistent, repeatable hole quality.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling operations in both shop and field environments where a standard jobber-length tool is appropriate. The 2.75-inch flute length accommodates drilling depths up to 2.75 inches, covering the majority of through-hole and blind-hole applications encountered in fabrication, mechanical maintenance, and general metalworking. Its general-purpose grade and uncoated finish make it compatible with both dry and lubricated cutting conditions on a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and superalloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter D size — 0.2460 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, and superalloys\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral flute promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to ANSI standards — general-purpose grade, right-hand cut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard keyed or keyless drill chucks accepting a 0.2460-inch straight-cylindrical shank.

Secure the straight-cylindrical shank firmly in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Apply cutting fluid or coolant as appropriate for the workpiece material to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2460 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: Bright\/Uncoated\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\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\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 11xD\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\u003eSeries\u003c\/strong\u003e: R10P-R15P-R18P\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, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 5998845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701849194802,"sku":"5998845","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a9595767adf1a1bebcf3507a2874d00_6c59c5d2-3b2b-44a3-a039-6a0742b524cc.jpg?v=1788405966","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998845-drill-bit-letter-d-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
