Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit is engineered for high-performance drilling in hard and abrasive materials. The web-thinned, tapered-web geometry reduces thrust and improves centering at start. Overall length is 1.5 inches with a flute length of 0.625 inches. Drill diameter tolerance is held to -0.0005 to 0.0000 inches, meeting the close-tolerance demands common in aerospace and precision metalworking applications.\u003c\/p\u003e\u003cp\u003eThis bit is rated for titanium as its primary workpiece material, making it well-suited to aerospace maintenance, precision machining, and manufacturing environments where conventional HSS bits fail prematurely. The straight-cylindrical shank fits standard drill chucks without modification. Its Series 550 designation indicates compliance with DIN 338 and NAS 907 Type J standards, which are commonly specified in aerospace and defense fabrication workflows. Installation is by a licensed machinist, tool-and-die professional, or qualified maintenance technician working with small-diameter precision drilling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for extended tool life in hard and abrasive materials including titanium\u003c\/li\u003e\n\u003cli\u003e135-degree split-point angle with web-thinned, tapered-web geometry for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eGold oxide coating reduces friction and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches for precision, close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for consistent chip clearing in deep holes\u003c\/li\u003e\n\u003cli\u003eMeets DIN 338 and NAS 907 Type J standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for No. 65 wire-gauge jobber-length drill bits in applications governed by NAS 907 Type J and DIN 338 specifications.

Secure the straight-cylindrical shank firmly in a calibrated drill chuck before operation and verify runout with a dial indicator when tolerance is critical. Avoid excessive feed pressure on wire-gauge diameter bits, as breakage risk increases significantly with lateral force. Always wear appropriate eye protection and follow applicable shop safety standards when drilling titanium or other hard alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular Helix)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 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: 550\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0009 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: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 46735\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749466439986,"sku":"46735","price":51.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_71982ffd-ae43-4ec7-9375-08f031580615.jpg?v=1788906453","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46735-cobalt-drill-bit-no-65-wire-size","provider":"Voomi Supply","version":"1.0","type":"link"}
