Measuring 0.1495 inches in diameter with a 135-degree split point, this bit delivers accurate starts and reduced walking on entry. The web-thinned, tapered web construction lowers cutting resistance and extends tool life under heavy-duty use. At 2.0625 inches overall length with a 1-inch spiral flute, the compact screw machine geometry suits close-quarters drilling where standard-length bits cannot reach. A straight-cylindrical shank allows direct chucking in standard drill chucks and machine spindles.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for high-performance drilling in titanium as its primary workpiece material, making it well suited for aerospace, HVAC equipment fabrication, and mechanical trades where titanium fastener holes or component bores are required. The coated finish reduces friction and heat buildup during cuts. Right-hand spiral flutes evacuate chips efficiently, keeping the cut clean. It meets ANSI and NAS 907 standards and carries a heavy-duty grade designation within the R41C series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance on hard materials including titanium\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 2.0625 inches overall for use in tight clearance applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes at 2.5xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 specification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty screw machine length replacement bit in wire size number 25 (0.1495 inches decimal), compatible with standard straight-cylindrical shank drill chucks and machine spindles accepting that shank diameter.

Ensure the workpiece is clamped or fixtured to prevent movement during drilling. When drilling titanium or other hard materials, use appropriate cutting fluid or coolant to manage heat, and operate at speeds and feeds appropriate for the workpiece material and bit diameter. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: Number 25\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: 2.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eSpiral Type\u003c\/strong\u003e: Regular\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\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\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: 0.1 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: 5998694\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722219487538,"sku":"5998694","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ca7e49c3ddabf4786fce666fa5a859e.jpg?v=1788587605","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998694-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
