Built to Series 769 specs, this bit measures 5\/16 inch (0.3125 inch) in diameter with a 120-degree point angle, a two-flute right-hand cutting configuration, and through-coolant capability via a round coolant hole. The submicron carbide grade provides the wear resistance and edge retention required for production drilling in non-ferrous and ferrous materials. The web-thinned geometry reduces thrust and improves chip evacuation. Installed by machinists and tool-and-die professionals, this bit is a direct fit for CNC machining centers and drill presses where coolant delivery and tight diameter tolerances are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production drilling operations in aluminum, aluminum alloys, and cast iron in both industrial and job-shop environments. The 7xD flute-to-diameter ratio supports drilling to a maximum depth of 2.523 inches (64.09 mm), making it appropriate for deep-hole applications where chip clearance and coolant flow are essential. The uncoated finish is well suited to aluminum where coatings can cause built-up edge. Operators working with CNC machining centers will benefit from the DIN 6535HA shank standard, which ensures consistent tool holding across compatible collets and chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for extended tool life in aluminum and cast iron\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability with round coolant hole for deep-hole chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry reduces thrust load and improves entry performance\u003c\/li\u003e\n  \u003cli\u003e120-degree standard point angle optimized for the primary workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDIN 6535HA shank specification for consistent tool holding in CNC setups\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.006 to +0.021 mm for controlled hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses equipped with DIN 6535HA-compatible tool holders.

Confirm the tool holder accepts a DIN 6535HA shank before mounting. Connect coolant lines per machine manufacturer specifications before initiating a drilling cycle. Do not exceed the rated maximum drilling depth of 2.523 inches without verifying chip clearance and coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Type\u003c\/strong\u003e: Straight-Flute Die Drill\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 116.00 mm (approximately 4.57 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 76.00 mm (approximately 2.99 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (approximately 0.315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (approximately 1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.523 inches (64.09 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 7xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes, Round Coolant Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Code K, N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Specification\u003c\/strong\u003e: DIN 6535HA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 769\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 9007690079400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727427240242,"sku":"9007690079400","price":360.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae03454f5093ae6cc6902a921fede0da.jpg?v=1788677804","url":"https:\/\/voomisupply.com\/products\/guhring-9007690079400-carbide-die-drill-bit-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
