The 135-degree split-point tip reduces walking and cutting force on entry, making it well suited for production and maintenance drilling in harder materials. A tapered web with web thinning further reduces thrust load. The straight-cylindrical shank fits standard three-jaw drill chucks without an adapter. This bit is intended for use by machinists, millwrights, maintenance technicians, and metal fabricators.\u003c\/p\u003e\n\u003cp\u003eThe 5996378 is engineered for drilling steel, stainless steel, cast iron, superalloys, and titanium. Its regular spiral flute geometry and 10xD flute-to-diameter ratio provide good chip evacuation in these materials. Overall length is 4.75 inches with a flute length of 3.4375 inches, giving adequate reach for most jobber-length applications on manual drill presses, CNC machining centers, and handheld power drills. It carries an ANSI specification designation and belongs to Precision Twist Drill Series HX10\/HX15\/HX18.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter Q size — 0.3320 inches decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split-point tip reduces walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction with bronze coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTapered web with web thinning reduces cutting resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks — no adapter needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for jobber-length drilling applications in steel, stainless steel, cast iron, superalloys, and titanium.

Secure the shank fully in the chuck and verify runout before beginning a cut. Follow the drill press or machine tool manufacturer guidelines for feed rate and speed selection based on workpiece material. Always use appropriate eye protection and ensure the workpiece is firmly clamped before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: Letter Q\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecimal Equivalent\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bronze (Purple\/Bronze)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard (Web-Thinned)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4375 inches (3-7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3320 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (1-5\/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: Regular Spiral\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\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: HX10\/HX15\/HX18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\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: 5996378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691403936050,"sku":"5996378","price":69.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/164a426c244a50dcd1df57227d075760_df3375f2-57d7-4240-8c08-08bf109caa4d.jpg?v=1788284597","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996378-drill-bit-letter-q-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
