At 9\/32 inches (0.2813 inches) in diameter, it features a 140-degree web-thinned point that reduces thrust force at entry and improves centering accuracy. The TiAlN coating adds heat resistance and extends tool life in demanding cut conditions. With an overall length of 3-7\/64 inches and a flute length of 1-39\/64 inches, this bit fits standard screw machine setups where compact, rigid tooling is preferred. It is suited for machinists, tool and die technicians, and CNC operators running production drilling cycles.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for general purpose drilling in a range of workpiece materials including steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The screw machine length format provides added rigidity compared to jobber length bits, making it well suited for close-tolerance drilling in production environments, manual drill presses, CNC machining centers, and turret lathes. The straight cylindrical shank at 0.3150 inches diameter seats securely in standard drill chucks and collet holders.\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 increases surface hardness and thermal resistance, extending tool life at higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree web-thinned point reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (3-7\/64 inches OAL) provides greater rigidity than jobber length alternatives\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry with 2 flutes promotes efficient chip evacuation in through-hole drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard spindle rotation; no coolant-through required\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 compatible with steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys; part of the WIDIA VDS201A series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit. Verify the drill chuck or collet is rated for the 0.3150-inch straight shank diameter and is properly torqued before starting a cut. Do not exceed the recommended maximum drilling depth of 1.14 inches without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/32 inches (0.2813 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/64 inches (3.11 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-39\/64 inches (1.61 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 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: 0.0470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0006 to 0.0000 inches\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: 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\/Finish\u003c\/strong\u003e: TiAlN\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\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 4143974\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67906058977586,"sku":"4143974","price":108.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b8d7cfc16ad8ad331c0792132caaf85_3f7ac904-d3ce-441c-8659-eaebc946d645.jpg?v=1791163756","url":"https:\/\/voomisupply.com\/products\/widia-4143974-screw-machine-drill-bit-9-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
