Built from high speed steel with a coated finish, this bit features a 135-degree split point that reduces walking and allows drilling to start without a center punch. The shortened screw machine length body provides added rigidity over jobber-length bits, making it well suited for drill press work, CNC setups, and production drilling where clearance is limited. The right-hand spiral flute with web thinning aids chip evacuation and reduces thrust in harder materials. Overall length is 1-13\/16 inches with a 13\/16-inch flute length.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in titanium and other hard-to-machine materials where a heavy-duty, high-performance cutting tool is required. The straight-cylindrical shank seats securely in standard drill chucks without slipping under load. Its screw machine length geometry makes it a common choice for production drilling, turret lathes, screw machines, and tight-clearance drill press fixtures in both shop and manufacturing settings. Sold individually; minimum order quantity is 12 units per order. This bit conforms to ANSI and NAS 907 specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers thrust on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction improves chip flow in hard materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for added wear resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length for increased rigidity in confined setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; rated for titanium as primary workpiece material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-grade option for standard straight-shank drill chucks accepting wire gauge size 38 (0.1015 inch diameter) bits in screw machine length configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this bit is performed by machinists, tool and die technicians, or maintenance mechanics using a standard keyed or keyless drill chuck. Ensure the machine is fully powered down and locked out before changing bits. Secure the straight-cylindrical shank firmly in the chuck to the full depth of the chuck jaws to prevent runout. Follow applicable shop safety protocols and applicable ANSI machining standards when selecting feeds and speeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 38\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 inches\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\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\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\u003ePoint Type\u003c\/strong\u003e: Split\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1000 to 0.1500 inches\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: R41C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5998577\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51708360818994,"sku":"5998577","price":40.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f248dbf4dc7a6591a9b892c51a62efa.jpg?v=1788445699","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998577-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
