Built to a wire gauge size of 42, this bit measures 0.0935 inches in diameter with a 1.75 inch overall length and a 0.75 inch flute length. The 135-degree split point geometry reduces walking on entry and requires less feed pressure than a standard 118-degree point. The two-flute regular spiral design promotes efficient chip evacuation. Cobalt construction provides elevated heat resistance compared to standard HSS bits, making it well suited to stainless steel, hardened alloys, and other hard materials common in precision machining and fabrication work.\u003c\/p\u003e\u003cp\u003eThis bit is sized for light-duty, close-tolerance drilling applications where screw machine length — shorter than jobber length — provides added rigidity and reduced deflection. It is commonly used in drill presses, screw machines, CNC machining centers, and production environments where consistency across multiple holes is critical. The straight shank fits standard chucks without adapters. Machinists, tool-and-die makers, and metalworking fabricators are the primary users of this bit size and geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 42 (0.0935 inches) for precise, close-tolerance drilling\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces walking and decreases required feed pressure\u003c\/li\u003e\n\u003cli\u003eCobalt tool material resists heat buildup in hard and abrasive metals\u003c\/li\u003e\n\u003cli\u003eScrew machine length (1.75 inch OAL) provides extra rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral promotes clean chip removal\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, straight shank, no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production-use bit for standard straight-shank drill chucks accepting wire gauge tooling in the 0.0000 to 0.1000 inch decimal inch size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and metalworking professionals. Secure the straight shank fully in the chuck and verify runout before beginning a drilling cycle. Power down or de-energize the machine completely before changing bits. Do not exceed the recommended speed range for cobalt bits in the material being drilled, and ensure the workpiece is properly clamped to prevent movement during the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0935 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 01378421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711986008370,"sku":"01378421","price":41.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acde463a12edfe53f2e62b00e8e44a2d.jpg?v=1788482300","url":"https:\/\/voomisupply.com\/products\/value-collection-01378421-size-42-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
