It carries a 6.7 mm diameter with a 130-degree cone relief point and a parabolic flute profile. The bright, uncoated finish keeps the tool ready for immediate use without additional prep. With a flute length of 97 mm and an overall length of 148 mm, this bit handles deeper drilling applications than standard jobber-length drills. It is installed by machinists, tool-and-die specialists, and maintenance technicians working with harder materials where cobalt tooling is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling into alloy steels, stainless steels, cast iron, and other tough materials in production or maintenance environments. The parabolic flute geometry improves chip evacuation during deep-hole drilling, reducing heat buildup and the need to peck cycle as frequently. The cylindrical shank fits standard drill chucks and collet systems without adapters. It is a right-hand cut tool designed for conventional CNC machining centers, drill presses, and hand-held drilling equipment where a taper length reach is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM-35 cobalt construction for improved heat and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e130-degree cone relief point for clean entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTaper length body provides extended reach compared to jobber-length drills\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry reduces centering force and improves cut initiation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 340 standard for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 340 taper length drill bit with a 6.7 mm cylindrical shank and h8 diameter tolerance, compatible with standard drill chucks and collet holders accepting 6.7 mm round-shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill chuck or collet is fully secured and the workpiece is clamped before engaging the spindle. Inspect the cutting edges and point geometry before each use and replace the bit if chipping or deformation is observed. Follow machine manufacturer guidelines for spindle speed and feed rate when working with cobalt tooling in hard materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 336\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.7 mm (0.2638 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 148 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 51 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.7 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 86.95 mm (3.423 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M-35)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Treatment\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\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: 9003360067000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731626033458,"sku":"9003360067000","price":73.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d40f3b9cd763590977670ac87216097e.jpg?v=1788733312","url":"https:\/\/voomisupply.com\/products\/guhring-9003360067000-taper-length-drill-bit-6-7mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
