Built from high speed steel with a coated finish, this bit features a 135-degree split point and web-thinned, tapered web construction that reduces walking and cutting resistance at entry. The straight-cylindrical shank measures 7\/64 inch (0.1094 inches) in diameter with an overall length of 1-13\/16 inches and a flute length of 13\/16 inches. The right-hand spiral flute design provides efficient chip evacuation during short-hole drilling operations. It meets ANSI and NAS 907 specifications and is rated heavy duty grade for demanding production environments.\u003c\/p\u003e\u003cp\u003eThis screw machine length bit is suited for drilling titanium and other hard materials in production machining, toolroom, and maintenance applications. The shorter-than-jobber flute-to-diameter ratio of 2.5xD provides added rigidity in screw machine and CNC lathe setups where stub-length tooling is required. Machinists, tool-and-die makers, and precision fabricators working in aerospace, manufacturing, and industrial maintenance will find this bit appropriate for close-tolerance hole work in tough stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/64 inch (0.1094 inches) diameter, screw machine length for increased rigidity\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and minimizes drill walking\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specifications, heavy duty grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement or production drill bit for use in standard drill chucks, collets, and screw machine spindles accepting a straight-cylindrical shank in the 0.1000 to 0.1500 inch diameter range.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully within the chuck or collet to the recommended grip depth to prevent runout. Follow applicable ANSI safety standards and machine manufacturer guidelines for speed and feed selection when drilling titanium or similarly hard workpiece materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/64 inch (0.1094 inches)\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\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R40C\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: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51711661375794,"sku":"5999450","price":41.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32908fc886be1bea000de19f7f9be531.jpg?v=1788478290","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999450-7-64-in-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
