Built from submicron-grade solid carbide, this bit delivers exceptional hardness and edge retention in demanding production environments. The tool measures 3.50 mm (0.1378 inches) in diameter with an overall length of 74.00 mm and features an uncoated finish suited to aluminum and similar workpiece materials. Coolant-through design with a round coolant-hole shape supports chip evacuation and heat management during deep-hole drilling. The drill carries a DIN 6535HA shank specification and a web-thinned point to reduce thrust on entry.\u003c\/p\u003e\n\u003cp\u003eThis drill is intended for precision machining applications in metalworking and die-making operations where tight tolerances and consistent hole geometry are required. Its 7xD flute-to-diameter ratio supports drilling depths up to 28.75 mm (1.132 inches), making it well suited for fixture work, mold components, and close-tolerance bores in aluminum, aluminum alloy, and cast iron workpieces. Installation is performed by qualified machinists on CNC machining centers or precision drill presses equipped with appropriate toolholding for a 6.00 mm straight shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for high edge stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with round coolant holes for effective chip removal and heat control\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned standard point at 120 degrees for reduced entry thrust and accurate positioning\u003c\/li\u003e\n  \u003cli\u003e7xD flute-by-diameter ratio supports drilling depths up to 28.75 mm\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with 2-flute geometry optimized for non-ferrous alloys\u003c\/li\u003e\n  \u003cli\u003eDIN 6535HA shank specification for precise toolholder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with toolholders conforming to DIN 6535HA standards.

Confirm that the toolholder bore and clamping mechanism are compatible with the 6.00 mm straight shank and DIN 6535HA specification before seating the tool. Verify coolant-through supply pressure and flow rate match the machine spindle's delivery capability before initiating a cut. Follow the tool manufacturer's recommended speeds and feeds for the target workpiece material to avoid premature edge wear or breakage.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.50 mm (0.1378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 28.75 mm (1.132 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 7xD\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Submicron Solid Carbide\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant-Hole Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: 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: 0.05 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: 9007690035000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737911623986,"sku":"9007690035000","price":288.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae03454f5093ae6cc6902a921fede0da_272e8ce5-1e69-41cc-b5ea-e9373c6fa710.jpg?v=1788795021","url":"https:\/\/voomisupply.com\/products\/guhring-9007690035000-die-drill-bit-0-1378-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
