Built from solid carbide with a bright\/uncoated finish, this bit delivers the hardness and edge retention needed when working through cast iron, stainless steel, carbon steel, and non-ferrous metals. At 0.157 inches in diameter (wire size 22), it features a 118-degree faceted point angle and a web-thinned parallel web for reduced thrust on entry. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. This bit is a Series 206 tool intended for machinists, tool-and-die professionals, and shop technicians running drill presses, CNC machining centers, or manual mills.\u003c\/p\u003e\u003cp\u003eThis drill bit suits precision metalworking applications where short overall length provides added rigidity and reduced deflection. The 2 inch overall length and 0.75 inch flute length make it well suited for shallow-hole operations in tight setups or fixture work. The right-hand spiral flute geometry evacuates chips efficiently during through-hole and blind-hole drilling in steel, stainless steel, cast iron, and non-ferrous alloys. It is sold as a single unit and is appropriate for professional machine shops, maintenance and repair operations, and production floor tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance in ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e118-degree faceted drill point for clean, accurate hole entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces axial thrust and improves penetration\u003c\/li\u003e\n\u003cli\u003eScrew machine (short) length provides added rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 3xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet toolholding systems\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and manual mills accepting a 0.157 inch straight-cylindrical shank.

Secure the shank fully in the chuck or collet holder and verify runout before operation. Always follow machine manufacturer speeds and feeds for solid carbide tooling in the target workpiece material. Ensure the spindle is fully stopped and the machine is powered down before changing or inspecting the bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Bit Diameter 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: 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: 20615700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51729686593842,"sku":"20615700","price":35.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01e7b23308cd60a4613f795d9f995e48_bf2d420a-d8cb-44e1-9355-c36b5525d48d.jpg?v=1788707788","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20615700-screw-machine-drill-bit-0-157-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
