Manufactured from high speed steel with a coated finish, this bit features a 135-degree split point and a web-thinned, tapered web configuration that reduces walking and improves penetration. At 0.147 inches in diameter with a straight-cylindrical shank, it is designed for use in standard drill chucks and CNC machines. The regular spiral flute with a 2.5xD flute-to-diameter ratio promotes efficient chip evacuation. Rated as a heavy duty bit, it meets ANSI and NAS 907 specifications.\u003c\/p\u003e\n\u003cp\u003eThis bit is optimized for drilling titanium as its primary workpiece material, making it well suited for aerospace, mechanical, and precision machining environments where titanium fastener holes and component bores are required. The screw machine length format — shorter than jobber length — provides greater rigidity and stability in tight clearance applications and machine tool setups. The overall length of 2-1\/16 inches and 1-inch flute length make it a practical choice for short-reach drilling operations on manual drill presses, lathes, and CNC machining centers. Each package contains one bit. Minimum order quantity is 12 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.147 inch diameter, wire size No. 26\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and minimizes bit walking on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web enhances penetration in hard materials including titanium\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine length design provides increased rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 specifications for precision and consistency\u003c\/li\u003e\n  \u003cli\u003eRight hand cut, regular spiral flute with 2.5xD flute-to-diameter ratio for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy duty OEM-style replacement or new-install drill bit for use in standard straight-shank drill chucks compatible with 0.147 inch diameter tooling.

Ensure the machine spindle is fully stopped and locked out before changing or securing bits in the chuck. Use appropriate cutting fluid or coolant when drilling titanium to manage heat buildup and extend tool life. Note that this bit does not support coolant-through application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.147 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: No. 26\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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: Split\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\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: 5998697\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51711418564914,"sku":"5998697","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec333d182fc06badb46a2293afb2fa00.jpg?v=1788476427","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998697-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
