Built to DIN 340 standards, it features a 0.0670-inch diameter with a parabolic flute geometry and a web-thinned, parallel web configuration that improves chip evacuation and reduces thrust during drilling. The 130-degree split point allows self-centering entry without a pilot hole. At 3 inches overall length with a 1-31\/32-inch flute length, this bit handles deeper holes than a jobber-length equivalent while maintaining rigidity. It is sold individually and suited for high-performance applications where standard HSS bits fall short.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in cast iron, hardened materials, stainless steel, and steel. The cobalt construction provides heat resistance and edge retention when cutting abrasive or work-hardening alloys. The bright, uncoated finish is typical for cobalt tooling where coating adhesion is secondary to base material performance. Right-hand cut, cylindrical shank, and no coolant-through design make it compatible with standard drill presses, CNC machining centers, and handheld drills equipped with a matching chuck. The 10xD flute-to-diameter ratio supports hole depths up to 1.868 inches in a single pass under appropriate feed and speed conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for heat resistance and edge retention in stainless steel and hardened materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute with web thinning for improved chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eDIN 340 taper length standard — longer than jobber length for increased reach\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through — compatible with conventional drilling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill presses, CNC machining centers, and handheld power tools with a chuck sized for a 0.0669-inch cylindrical shank.

Secure the workpiece firmly before drilling and verify chuck runout to protect the small-diameter shank from breakage. When drilling stainless steel or hardened materials, use appropriate cutting fluid and avoid dwelling at low feed rates, which can work-harden the material. Disconnect power to any machine tool before changing bits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.868 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0669 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Hardened Materials, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 336\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9003360017000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738122977586,"sku":"9003360017000","price":48.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c0d959cb057282ae4bb1a3b6222fb0_cca7ba82-c532-4ee7-81ab-d5ded6749134.jpg?v=1788796334","url":"https:\/\/voomisupply.com\/products\/guhring-9003360017000-taper-length-drill-bit-0-0670-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
