Built from high-speed steel with a bright\/uncoated finish, it features a 135-degree split point that reduces walking and lowers thrust at entry. The shortened screw machine length body — 2-1\/16 inches overall — provides added rigidity compared to jobber-length bits, making it well suited for drill press and CNC work where chatter and deflection are concerns. Two spiral flutes with a regular helix and parallel web configuration clear chips efficiently throughout the cut.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for production and job-shop environments where wire-gauge sizing is specified. At 0.1440 inches in diameter, it covers common tapping and clearance holes in ferrous and non-ferrous stock. The web-thinned split point is particularly useful when drilling alloy steel, aluminum, and similar materials where a standard chisel point would require pre-spotting. It is sold individually and is part of the CLEVELAND Series 2330 heavy-duty line, which is built to ASME B94.11M standards and meets NAS 907 Type C specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces entry thrust and eliminates the need for a center punch on most materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (2-1\/16 inches OAL) delivers superior rigidity over standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles alloy steel, aluminum, and general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1440 inches diameter fits standard drill chucks and collets without adapters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and NAS 907 Type C specifications for use in controlled production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill presses, CNC machining centers, and hand-held drill motors equipped with chucks or collets accepting a 0.1440-inch straight-cylindrical shank.

Ensure the workpiece is clamped securely — screw machine length bits are stiff but small-diameter drills remain susceptible to breakage if the part shifts during entry. Apply appropriate cutting fluid for the workpiece material to extend edge life and improve hole finish. Follow shop safety protocols and applicable OSHA machine-guarding requirements when operating drill presses or CNC equipment.\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. 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1440 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\u003eOverall Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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 -0.0007 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\u003eStandards\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: C70331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711694209330,"sku":"C70331","price":42.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65d59c5d84d088f5fd5069571a2a0a7a_919dc00d-e7c2-43ba-97de-08d542529fdc.jpg?v=1788478579","url":"https:\/\/voomisupply.com\/products\/cleveland-c70331-no-27-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
