Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting hard and abrasive materials. The 135-degree split point reduces walking and requires no center punch on most surfaces. At 2.125 inches overall length, the short-flute screw machine geometry provides added rigidity, making it well suited for CNC machine tools, drill presses, and production drilling setups where deflection must be minimized.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in metalworking applications involving alloy steel and aluminum. The screw machine length format is common in production environments where short, rigid tooling improves hole accuracy and reduces chatter. Licensed machinists, tool-and-die technicians, and maintenance mechanics will find this bit appropriate for high-cycle drilling operations on ferrous and non-ferrous workpiece materials. The Series 2133 designation places it within a heavy-duty cobalt drill line built to ASME B94.11M and DIN 1897 standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction provides superior heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates center-punch requirements on most materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration improves chip evacuation and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.125 inches OAL) adds rigidity for precision, high-cycle drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute regular spiral geometry for general metalworking use\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use with 3-jaw drill chucks and straight-shank collet holders accepting a 0.1570-inch straight-cylindrical shank, suitable for drill presses, CNC machining centers, and hand-held drill motors used in alloy and aluminum machining.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians familiar with rotating cutting tools. Secure the straight-cylindrical shank fully in a compatible chuck or collet before operation and verify runout with a dial indicator when precision is critical. Always power down and lock out the machine spindle before changing tooling. Do not exceed the recommended speed and feed range for the workpiece material and drill diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1570 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: 0.1570 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: Cobalt M42\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2133\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B94.11M, ANSI, DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: C14591\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693687243058,"sku":"C14591","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f44119298e96f37633fd1b319eae812b.jpg?v=1788316092","url":"https:\/\/voomisupply.com\/products\/cleveland-c14591-cobalt-drill-bit-no-22-0-1570-in","provider":"Voomi Supply","version":"1.0","type":"link"}
