Built from solid carbide with a bright\/uncoated finish, this bit measures 0.375 inches in diameter with an overall length of 3.125 inches and a flute length of 1.8125 inches. The 135-degree split point reduces walking on entry and lowers thrust force, making it well-suited for production drilling where accuracy and tool life matter. Right-hand cut with a slow spiral, parallel web, and web-thinned geometry, this bit is used by machinists and tool-and-die professionals working with tight tolerances.\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 — shorter than a jobber bit — provides added rigidity and reduced deflection, which is particularly useful when drilling in CNC machining centers, turret lathes, or screw machines where stub-length tooling is preferred. The straight-cylindrical shank fits standard drill chucks and collet holders. The 3xD flute-to-diameter ratio and slow spiral geometry promote chip evacuation in interrupted cuts and gummy materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute promotes chip clearance in stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web geometry improves cutting efficiency and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains dimensional accuracy for close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches ensures consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces.

Carbide is brittle — avoid side loading, interrupted feeds, or over-tightening in the chuck, as these can cause chipping or breakage. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Coolant-through is not supported by this bit; use flood or mist coolant at the entry point when drilling stainless steel or cast iron to manage heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 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\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, 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: 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\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: 20537500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51733074936114,"sku":"20537500","price":155.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_d60a15f6-c10a-4df1-bafc-5582a7e3164c.jpg?v=1788751133","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20537500-screw-machine-drill-bit-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
