Built to NAS 907 Type J specification, this heavy-duty bit features a 135-degree split point that reduces walking on contact and requires no center punch on most surfaces. At wire gauge size 40 (0.098 inches diameter), it suits precision work in close-tolerance applications. The 2-flute spiral design evacuates chips efficiently while the bright uncoated cobalt construction resists heat buildup during extended cutting cycles. Machinists, tool and die workers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is sized for wire gauge number 40 work, which appears frequently in sheet metal fabrication, aerospace maintenance, and general metalworking applications requiring small-diameter holes. The screw machine length body is shorter than a jobber bit, providing added rigidity and reduced deflection in drill press, CNC, and hand-held drill applications. The straight-cylindrical shank fits standard 3-jaw chucks without adapters. Right-hand cut with spiral fluting suits conventional drilling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for heat resistance in hard and stainless steel materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates walking without a center punch\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (1-13\/16 inches overall) provides extra rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J specification for dimensional and performance standards\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows direct visual inspection of cutting edge condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty screw machine length drill bit in the 0.0000 to 0.1000 inch (0.00 to 3.50 mm) size range, compatible with any standard drill press, CNC machine, or hand drill fitted with a 3-jaw chuck accepting straight-cylindrical shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians familiar with small-diameter drill bits. Secure the straight-cylindrical shank firmly in the chuck before operation to prevent slippage and bit breakage. At this diameter, feed rate and RPM selection are critical — consult published cutting speed tables for cobalt bits in the specific workpiece material. Ensure the workpiece is clamped securely before drilling to prevent movement that can snap small-diameter bits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.098 inches (2.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 40\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 (0.8125 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD32640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51738574225714,"sku":"CD32640","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54372cdd8d04e566e12f562cd92e481c_dd1c56b8-b8d3-4ed7-ae49-19f4ad8869b6.jpg?v=1788801185","url":"https:\/\/voomisupply.com\/products\/titan-usa-cd32640-screw-machine-drill-bit-wire-40-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
