Sized at 0.4062 inches (13\/32 inch) in diameter, it features a 118-degree faceted point angle with web thinning for reduced thrust and cleaner entry. The two-flute spiral design in a straight-cylindrical shank configuration delivers consistent chip evacuation in short-reach drilling applications. Machinists and tool-room technicians working with production equipment, CNC machining centers, or drill presses rely on this bit where rigidity and dimensional accuracy are priorities.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for short-reach drilling operations in cast iron, non-ferrous metals, stainless steel, and steel. The stub length body reduces deflection compared to jobber-length bits, making it a practical choice for tight-tolerance work in production environments. The bright\/uncoated finish keeps the carbide substrate exposed for direct heat dissipation and easy wear inspection. It is sold individually and is appropriate for both manual and CNC-controlled spindle applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning reduces axial cutting force and improves hole entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body minimizes deflection in close-clearance setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute spiral geometry for consistent chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.4062 inches fits standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for precise fit applications\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup to affect diameter or edge sharpness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and manual or automated drilling equipment that accept a 0.4062-inch straight-cylindrical shank.

Secure the shank fully in a collet or drill chuck rated for the shank diameter before engaging the spindle. Solid carbide is brittle — avoid side-loading, interrupted cuts beyond the tool design intent, or re-chucking on a worn shank seat, as these can cause tool fracture. Always verify spindle runout is within tolerance before production use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 13\/32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4062 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Short (Screw Machine)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 206\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: 20640620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51738607747378,"sku":"20640620","price":116.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01e7b23308cd60a4613f795d9f995e48_770f7db6-4aab-481e-a3ad-e9c6d0344341.jpg?v=1788801707","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20640620-carbide-screw-machine-drill-bit-0-4062-in","provider":"Voomi Supply","version":"1.0","type":"link"}
