At 8.8 mm (0.3465 inch) in diameter with a 130-degree split point and parabolic flute geometry, this bit is built to handle cast iron and steel with reduced heat buildup and improved chip evacuation. The web-thinned, tapered-web construction lowers thrust requirements at entry. Machinists, tool-and-die technicians, and maintenance mechanics reach for this series when standard HSS bits underperform in tough ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for jobber-length drilling operations in ferrous metals, particularly cast iron and steel, across manufacturing, fabrication, and heavy maintenance settings. The straight-cylindrical shank accepts standard drill chucks on CNC machining centers, knee mills, drill presses, and handheld power tools. The parabolic flute profile supports efficient chip clearing in deep-hole applications up to a maximum drilling depth of 2.67 inches (67.80 mm). Series 658 is manufactured to DIN 338 standards, providing consistent dimensional accuracy within a diameter tolerance of -0.022 to 0.000 mm.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt substrate with TiN coating for extended tool life in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle with web thinning for reduced entry thrust and clean starts\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design promotes fast, reliable chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for consistent sizing and runout control\u003c\/li\u003e\n  \u003cli\u003eTapered web construction adds rigidity and resists deflection during drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces (material codes K and P). Compatible with any standard drill chuck sized for a 0.3465-inch straight shank.

Power down or de-energize the machine completely before inserting or removing the bit. Use appropriate cutting fluid or coolant for the workpiece material even though this bit does not feature through-coolant capability. Follow applicable shop-safety standards and machine-specific operating procedures when setting spindle speed and feed rate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.8 mm (0.3465 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-29\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.67 inches (67.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3465 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 44.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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\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\u003eBit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.022 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 658\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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: 9006580088000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750491554098,"sku":"9006580088000","price":117.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18b87ae31f6b87cd92e580456479661c_5af8ae84-f390-46f8-9d56-d01b63af99af.jpg?v=1788915855","url":"https:\/\/voomisupply.com\/products\/guhring-9006580088000-cobalt-jobber-drill-bit-8-8-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
