Ford 20638600 Screw Machine Drill Bit 0.386 in","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD 20638600 is a solid carbide screw machine length drill bit with a 0.386 inch diameter and a 118-degree faceted drill point angle. Designed for short-length, high-rigidity drilling applications, it runs a 2-flute spiral flute configuration with a right-hand cut. The bright\/uncoated finish suits shops that prefer uncoated carbide for specific material compatibility. At 2-3\/4 inches overall length with a 1-1\/4 inch flute length, this bit is built for close-quarters drilling where a jobber-length bit would be impractical. Machinists, tool and die shops, and general metalworking operations will find this bit suited to precision hole-making in production environments.\u003c\/p\u003e\u003cp\u003eThe 20638600 is appropriate for drilling cast iron, non-ferrous metals, stainless steel, and steel. The web-thinned, parallel web construction reduces thrust requirements at the drill point, which is especially useful when working stainless steel or other materials that generate heat and work-harden quickly. The straight-cylindrical shank measures 0.386 inches in diameter with a 1-1\/2 inch shank length, fitting standard drill chucks and collet systems. The Series 206 designation places this bit in M.A. FORD's short-flute carbide line, with a flute-to-diameter ratio of 3xD.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in metalworking applications\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning to reduce entry thrust\u003c\/li\u003e\n\u003cli\u003eScrew machine (short) length at 2-3\/4 inches overall for close-tolerance setups\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with parallel web configuration\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and lubricants\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 0.386 inch straight-cylindrical shank.

Secure the shank firmly in a properly sized collet or drill chuck before operation. Always apply an appropriate cutting fluid for the workpiece material, particularly when drilling stainless steel. Inspect the cutting edges and web for wear or chipping before each use and replace if the point geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.386 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.386 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\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\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\u003eDrill Length Type\u003c\/strong\u003e: Short\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 20638600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51730601738546,"sku":"20638600","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01e7b23308cd60a4613f795d9f995e48_f71b7e74-46b0-4c93-93f2-778adf57f2c7.jpg?v=1788720173","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20638600-screw-machine-drill-bit-0-386-in","provider":"Voomi Supply","version":"1.0","type":"link"}
