Measuring 0.144 inches in diameter (Wire Size 27), it features a 135-degree split point with web thinning to reduce thrust and improve centering without a center punch. The overall length of 2.0625 inches and the shortened flute geometry of screw machine length tooling make it well suited for rigid setups where rigidity and chip evacuation are priorities. Right-hand cut with a slow spiral, two-flute configuration, this bit is intended for machinists, tool-and-die tradespeople, and CNC operators running production work on precision components.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, and steel. The screw machine length format is commonly found in turret lathes, machining centers, and drill presses where stub-length tooling reduces deflection on close-tolerance work. The straight-cylindrical shank at 0.1440 inches diameter seats directly into standard collets or drill chucks without adapters. It is a single-margin design with no coolant-through capability, making it appropriate for conventional flood coolant or dry cutting setups in shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides hardness and wear resistance for production drilling in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and cutting thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.0625 inches overall improves rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eSlow spiral, two-flute design promotes controlled chip evacuation in deep holes relative to diameter\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish  -  no coating thickness to account for in tight-tolerance diameter applications\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches ensures consistent hole sizing for close-fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 205 screw machine length drill for use in cast iron, non-ferrous metal, stainless steel, and steel workpiece materials.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or chuck runout is within acceptable limits before use, as carbide tooling is sensitive to side-loading and vibration. Solid carbide bits are brittle relative to high-speed steel  -  avoid interrupted cuts or conditions that produce lateral shock without confirming the application is appropriate for carbide.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0625 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: 1.0625 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\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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: Slow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: M.A. FORD.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20514400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51744035078450,"sku":"20514400","price":44.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_207b19d9-01f4-40ad-999f-2cf143f9edd7.jpg?v=1788853321","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20514400-screw-machine-drill-bit-0-144in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
