Built from high-speed steel with a bright, uncoated finish, this bit features a 135-degree split point that reduces walking and allows drilling to start without a center punch. The web-thinned, parallel-web construction lowers cutting resistance and helps clear chips efficiently. At 0.1730 inches in diameter with an overall length of 2.1875 inches, it is sized for tight-clearance drilling operations where a jobber-length bit would not fit. A straight-cylindrical shank provides secure retention in standard drill chucks and quick-change holders.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in screw machine shops, production drilling setups, and general metalworking environments. It is suited for drilling alloy steel and aluminum in applications that demand close-tolerance holes. The wire size 17 designation corresponds to a 0.1730-inch diameter, which falls within the 0.1500 to 0.2000 inch diameter range. Its short flute length and reduced overall length make it appropriate for CNC turret operations, drill presses, and hand-held power tools where rigidity and precision matter. Licensed tradespeople and machinists in manufacturing and maintenance roles are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces bit walking and lowers entry force on hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel-web design improves chip evacuation and reduces thrust load\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles alloy steel and aluminum at standard cutting speeds\u003c\/li\u003e\n\u003cli\u003eScrew machine length at 2.1875 inches overall provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and quick-change systems\u003c\/li\u003e\n\u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specifications for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production-use drill bit for standard drill chucks and quick-change holders accepting a 0.1730-inch straight-cylindrical shank across screw machine, CNC turret, and drill press setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by a qualified machinist or tradesperson familiar with metal cutting operations. Secure the shank fully in the chuck and verify runout before beginning a drilling cycle. Power down and de-energize any machine tool before changing or securing the bit. Follow the machine manufacturer recommended speeds and feeds for the target workpiece material to avoid premature bit wear or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1730 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1730 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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: 2330\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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\u003eWeight\u003c\/strong\u003e: 0.2 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C70321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700681474354,"sku":"C70321","price":50.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_3ca9c30f-d0ba-48e0-b181-5e7f130a38cb.jpg?v=1788393749","url":"https:\/\/voomisupply.com\/products\/cleveland-c70321-screw-machine-drill-bit-wire-17-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
