Built from high-speed steel with a bright\/uncoated finish, it measures 0.0890 inches in diameter and 1.75 inches overall length. The 135-degree split point reduces walking and cutting force at entry, making it well suited for production drilling on harder workpiece materials. The parallel web and web-thinned geometry help maintain chip clearance through the 0.75-inch flute length. Machinists, tool-and-die technicians, and precision fabricators typically reach for this bit in screw machine and CNC drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe C70347 is sized for small-diameter work in alloy steel and aluminum, which are its rated primary workpiece materials. The screw machine length body fits standard drill chucks and collet holders without modification. With a 1.0-inch straight-cylindrical shank at 0.0890 inches diameter and a right-hand spiral cut, it runs in conventional clockwise-rotating spindles. The short overall length provides added rigidity, reducing deflection in repetitive production runs or when drilling without a pilot hole. This bit conforms to ASME B94.11M and meets NAS 907 Type C specification requirements, making it appropriate for aerospace-adjacent and precision manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 43 wire gauge diameter: 0.0890 inches, tolerance +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and minimizes center walking on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 1.75 inches overall provides increased rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for alloy steel and aluminum workpieces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web design improves chip evacuation through the 0.75-inch flute\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C standards for precision and aerospace applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-supply bit for screw machine and CNC drilling operations requiring a No. 43 wire gauge, straight-cylindrical shank drill bit in the Cleveland Series 2330 product line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a standard drill chuck or collet rated for a 0.0890-inch straight shank and confirm secure seating before operation. Run at spindle speeds appropriate for the workpiece material and bit diameter per standard machining feeds-and-speeds references. Avoid side-loading or flexing the bit during retraction, as small-diameter HSS bits are susceptible to breakage under lateral stress. Inspect the split point for chipping before each use, particularly in high-cycle production environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, NAS 907 Type C\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: 0.1 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51689005449522,"sku":"C70347","price":41.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a.jpg?v=1788253661","url":"https:\/\/voomisupply.com\/products\/cleveland-c70347-no-43-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
