Built from solid carbide and coated with TiAlN for heat and wear resistance, this bit delivers consistent results across a range of ferrous and non-ferrous materials. The 140-degree web-thinned point reduces entry thrust and improves centering on hard materials. At 3.5 inches overall length with a 1.85-inch flute length, this is a stub-length format suited for close-tolerance work in rigid setups. It is installed and used by machinists, tool-and-die technicians, and maintenance professionals working with drill presses, CNC machining centers, and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe 4143995 is rated for general-purpose drilling in steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys. The screw machine length format makes it well suited for drilling in fixtures, jigs, or tight-clearance setups where a jobber-length bit would extend too far. The straight cylindrical shank fits standard chucks and collets in both CNC and manual machine tool applications. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 1.38 inches, this bit is optimized for shallow-to-medium-depth holes requiring accuracy and surface finish.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves thermal resistance and extends tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree web-thinned point reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length format minimizes deflection in short-reach drilling setups\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral design promotes chip evacuation in a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with 0.3937-inch diameter fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit for use in steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys.

Ensure the machine spindle is fully stopped and the chuck is properly secured before inserting or removing the bit. Verify runout and chuck condition before use, as excessive runout will accelerate edge wear on solid carbide tooling. Follow the machine manufacturer and tooling manufacturer guidelines for feed rate and spindle speed for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inches (0.3438 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.85 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.058 inches\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\u003ePoint Type\u003c\/strong\u003e: Web-Thinned\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VDS201A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.156 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4143995\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67910578864434,"sku":"4143995","price":116.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b8d7cfc16ad8ad331c0792132caaf85_fca4b07f-51e4-43d3-bc0f-a78ad8f7a1ed.jpg?v=1791198894","url":"https:\/\/voomisupply.com\/products\/widia-4143995-screw-machine-drill-bit-11-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
