Manufactured from high speed steel with a coated finish, this bit features a 135-degree split point that reduces walking and lowers thrust on entry. The straight-cylindrical shank seats securely in standard chucks. At 0.323 inches in diameter and 2-15\/16 inches overall length, this is a stub-length bit built for rigidity and reduced deflection in short-reach drilling operations. Licensed machinists, tool and die technicians, and industrial maintenance trades are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling titanium and similarly tough workpiece materials where a standard twist drill would deflect or chatter. The screw machine length format keeps the cutting edge close to the chuck, maximizing stiffness. Series R42C denotes a heavy-duty, high-performance classification. The 1-11\/16-inch flute length and 2.5xD flute-to-diameter ratio are suited for shallow-to-moderate depth holes in production and MRO environments. The right-hand cut and regular spiral type are consistent with conventional drill press, CNC, and handheld power tool applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces center walking and decreases feed pressure on hard materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life on titanium and hard alloys\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length design maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without modification\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards for dimensional accuracy and material grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and handheld power tools accepting a straight-cylindrical shank. Rated for primary workpiece material titanium; also suitable for other hard metals within the Series R42C heavy-duty application range. Drill bit size falls within the 0.3000 to 0.3500 decimal inch range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck and confirm runout before drilling. When working titanium or hard alloys, use appropriate cutting fluid and avoid excessive feed pressure that can work-harden the material or overheat the cutting edge. Inspect the split point for chipping before each use; a damaged point will increase thrust and reduce hole quality. Follow shop-specific speeds and feeds for the workpiece material and bit diameter.\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: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R42C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: 5999408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51690081976626,"sku":"5999408","price":16.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9145d20a4e69233cfa8036765dba6cbd.jpg?v=1788266412","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999408-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
