It features a 118-degree split-point tip and a regular spiral flute geometry, producing clean, accurate entry holes with minimal walking on startup. The straight-cylindrical shank accepts standard drill chucks without adapters. With an overall length of 3.5 inches and a flute length of 2.3125 inches, this is a general-purpose bit suited for production and maintenance drilling tasks. It is rated as heavy-duty grade and meets NAS 907 Type A specification. Licensed machinists, maintenance technicians, and fabricators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling aluminum as its primary workpiece material, though the high-speed steel construction and standard jobber geometry also handle a range of soft to medium ferrous and non-ferrous materials in typical shop and field environments. The wire size 12 diameter falls within the 0.1500 to 0.2000 inch range common in precision fastener clearance, tapping pilot, and light structural applications. It is packaged as a single bit and sold in multiples of 12, making it suitable for shop restocking or toolcrib replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 12 with 0.1890 inch decimal diameter and tight tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree split point with web-thinned, tapered web for reduced thrust and self-centering starts\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated heavy-duty grade for extended tool life\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with cutting fluids and suitable for aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with right-hand cut for standard drill press, hand drill, and CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type A specification for consistent dimensional conformance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill bit conforming to NAS 907 Type A standards, suitable for use in any standard drill chuck accepting a 0.1890 inch straight-cylindrical shank across drill presses, hand drills, and CNC drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance technicians, or fabricators using a standard drill chuck sized for a straight-cylindrical shank. Ensure the workpiece is securely clamped and the machine is at a full stop before changing or seating the bit. Apply appropriate cutting fluid when drilling aluminum or other non-ferrous metals to extend tool life and improve hole finish. Inspect the split point for wear or chipping before each use, as a damaged tip will reduce positional accuracy and increase thrust load.\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: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 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: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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: 0.3 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: C73440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709053600050,"sku":"C73440","price":54.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f364efd6aec19afa2f91a820fcff892a_f84e1d81-77b5-4149-8d47-696b52e10d3e.jpg?v=1788450549","url":"https:\/\/voomisupply.com\/products\/cleveland-c73440-jobber-length-drill-bit-wire-12-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
