Built to ANSI standards, this Series 2601 bit features a 130-degree point angle and a parabolic flute geometry that promotes efficient chip evacuation. The submicron carbide substrate provides the hardness and wear resistance required for consistent performance in high-volume drilling operations. At 3.75 inches overall length with a 2.5-inch flute, it delivers the reach needed for standard jobber applications. The bright uncoated finish suits applications where coating-induced dimensional changes are a concern. Licensed machinists and precision toolroom technicians are the primary installers of this bit type.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for drilling aluminum as its primary workpiece material, with material codes K, N, and P indicating suitability across non-ferrous metals and certain plastic and composite materials. The No. 4 wire gauge size corresponds to 0.2091 inches in decimal inch. Straight-cylindrical shank diameter matches the bit diameter at 0.2091 inches, making it compatible with standard drill chucks and collet systems. The 8xD flute-to-diameter ratio supports a maximum drilling depth of 2.254 inches. The parabolic flute profile reduces friction and heat buildup during extended cuts in soft to medium-hardness materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade substrate for enhanced hardness and tool life\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces walking and lowers thrust requirements at entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry accelerates chip clearance in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains tight dimensional tolerance: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series 2601 design for consistent interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks and precision collet systems accepting a 0.2091-inch straight-cylindrical shank.

Ensure the spindle and chuck are fully de-energized and at a complete stop before inserting or removing the bit. Solid carbide is brittle relative to high-speed steel; avoid side-loading or using in impact-type drivers. Verify chuck runout is within acceptable limits before use to prevent premature bit failure or oversized holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2091 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches (95.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.254 inches (57.24 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2091 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.224 inches (31.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Codes K, N, P)\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: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9026010053100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51787876991282,"sku":"9026010053100","price":114.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d27ae7826d7b1c2d70d9139d5a9b5622_05d3ef9c-29bb-4780-ad72-1bcc79a43ee8.jpg?v=1789219578","url":"https:\/\/voomisupply.com\/products\/guhring-9026010053100-carbide-jobber-drill-bit-no-4","provider":"Voomi Supply","version":"1.0","type":"link"}
