Measuring 0.0935 inches in diameter (Wire Size 42), it features a 135-degree split point with web thinning for reduced thrust and accurate self-centering on entry. The two-flute slow spiral design with a straight-cylindrical shank suits high-speed drilling operations where hole quality and tool life are priorities. Machinists, tool and die makers, and production drilling technicians working with tight tolerances will find this bit a reliable choice for short-hole applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use on cast iron, non-ferrous metals, stainless steel, and steel. The screw machine length format provides added rigidity compared to jobber-length bits, making it well matched to drill press, CNC machining center, and manual lathe operations where stub-length reach is sufficient. The bright uncoated finish is appropriate for applications where coating interaction with workpiece material is a concern, and the solid carbide construction supports higher cutting speeds than high-speed steel alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life on hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e135-degree drill point angle with web thinning reduces walking and entry thrust\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry suited to cast iron, stainless steel, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eScrew machine length provides greater rigidity than jobber-length bits in short-reach setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on cast iron, non-ferrous metal, stainless steel, and steel workpieces.

Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the spindle speed being used. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper feed rate adjustment, and dropping the tool. Follow machine manufacturer guidelines for spindle speed and feed rate when drilling the listed workpiece materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0935 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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\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\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\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: 0.0935 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inches\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 20509350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51751479869746,"sku":"20509350","price":33.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_5aab4967-557e-419b-be32-c158c819daf9.jpg?v=1788923570","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20509350-carbide-screw-machine-drill-bit-42","provider":"Voomi Supply","version":"1.0","type":"link"}
