Built to ASME B94.11M and NAS 907 Type C standards, it features a 135-degree split point that reduces walking and requires no center punch on most materials. The bright, uncoated finish suits general-purpose drilling where coating buildup is a concern. At 1-11\/16 inches overall length, this stubby format provides rigidity in screw machine, CNC, and drill press applications. Installation is handled by machinists and tool-room technicians working in production or job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling alloy steels and aluminum in tight-tolerance applications where a short, stiff drill body reduces deflection. The parallel web configuration and web-thinned geometry improve chip evacuation and reduce thrust load. Its straight cylindrical shank fits standard collets, chucks, and quick-change tooling commonly found in screw machines and machining centers. The heavy-duty grade construction supports repeat-cycle production use where consistent hole quality across large run quantities is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 52 with 0.0635-inch diameter and tight tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers thrust during entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web design improves chip flow and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (1-11\/16 inches OAL) provides maximum rigidity\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated for heavy-duty, high-cycle production use\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw machines, CNC machining centers, and drill presses with standard straight-cylindrical chuck or collet systems; primary workpiece materials include alloy steel and aluminum.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed by machinists and tool-room operators in machine tool setups. Ensure the spindle is fully stopped and de-energized before changing tooling. Secure the shank fully in the collet or chuck to the manufacturer-specified engagement depth to prevent pullout during operation. Verify workpiece fixturing and coolant setup before starting a production run; this bit is configured without coolant-through capability, so external coolant or cutting fluid application is recommended when drilling alloy steels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0635 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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Aluminum\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: 2330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907 Type C\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51973773132082,"sku":"C70356","price":42.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_7305dd4c-4eae-4605-b869-81216e0155f0.jpg?v=1789974520","url":"https:\/\/voomisupply.com\/products\/cleveland-c70356-screw-machine-drill-bit-52-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
