Sized at wire gauge 21 (0.1590 inches decimal), it features a 135-degree split point with web thinning for fast engagement and reduced walking on entry. The overall length of 2.125 inches and shortened flute length make it well suited for drill press and CNC screw machine work where rigidity matters. A bright, uncoated finish keeps the steel at its native hardness. This bit is installed and used by machinists, tool-and-die technicians, and skilled tradespeople working in production or maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThe C70325 is built for drilling into alloy steel and aluminum, two of the most common workpiece materials in light manufacturing and mechanical contracting. Its screw machine length profile — shorter than jobber length — reduces deflection when drilling at higher feed rates or in interrupted cuts. The straight-cylindrical shank seats securely in standard drill chucks and collet holders without modification. This bit is typically used in repetitive-hole applications such as tapping prep, clearance holes, and pilot drilling on structural or component assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 21 (0.1590 inches) with diameter tolerance of +0.0000 to -0.0007 inches for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust force and self-centers on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 2.125 inches overall provides added rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated heavy duty for alloy and aluminum workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect hole diameter tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral, 2 flutes — compatible with standard drill chucks and CNC tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement drill bit for use in standard drill press, CNC, and hand-held drill chuck setups accepting a 0.1590-inch straight-cylindrical shank.

Disconnect and lock out all power to the machine before changing bits. Apply cutting fluid appropriate for the workpiece material — particularly when drilling alloy steel — to extend tool life and maintain hole quality. Follow applicable OSHA machine guarding requirements and shop safety protocols for rotating cutting tools.\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: 21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0625 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: 0.1590 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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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 Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\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: C70325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51717945393458,"sku":"C70325","price":43.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_1ae63c77-8c50-4be6-83bb-d1114a71811f.jpg?v=1788547668","url":"https:\/\/voomisupply.com\/products\/cleveland-c70325-screw-machine-drill-bit-wire-21-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
