Built to DIN 6535HA specification, it features a 120-degree point angle, web-thinned geometry, and through-coolant capability with a round coolant-hole profile. The submicron carbide grade provides the edge retention and thermal stability required for demanding production environments. At 12 mm in diameter with a 4xD flute-to-diameter ratio, this bit is suited for consistent, repeatable hole quality in metalworking and machining applications. It ships individually and is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in CNC machining centers, drilling machines, and similar rigid setups where straight-flute geometry and through-coolant delivery deliver clean, accurate holes. Primary workpiece materials include aluminum, aluminum alloy, and cast iron. The bright, uncoated finish makes it appropriate for non-ferrous and gray iron applications where coating interaction or heat buildup from coated tools is a concern. Right-hand cutting direction, two flutes, and a standard point type make this a straightforward drop-in for production or job-shop drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with round coolant holes for effective chip evacuation and heat management\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned point reduces thrust force and improves centering at entry\u003c\/li\u003e\n  \u003cli\u003e120-degree point angle optimized for aluminum and cast iron workpieces\u003c\/li\u003e\n  \u003cli\u003eStraight-flute design provides rigidity and surface finish consistency in low-chip-curl materials\u003c\/li\u003e\n  \u003cli\u003eDIN 6535HA shank specification ensures accurate, repeatable tool holding in standard ER and hydraulic chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in rigid machine tool setups conforming to DIN 6535HA toolholder standards; rated for aluminum, aluminum alloy, and cast iron workpiece materials as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a DIN 6535HA-compatible chuck or collet and verify runout before cutting. Ensure the coolant system is active and delivering adequate flow through the spindle before engaging the workpiece. Do not use this tool in hand-held drilling applications; straight-flute carbide tooling requires a rigid, vibration-controlled setup to prevent chipping 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 120 degrees\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes, Round Coolant Holes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6535HA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 768\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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: 9007680120000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747221307698,"sku":"9007680120000","price":475.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/942dd424cb11b24ddb632813b1e42d54_d840a53e-b354-4d1c-ac65-fb7d5d71f2cd.jpg?v=1788877645","url":"https:\/\/voomisupply.com\/products\/guhring-9007680120000-straight-flute-drill-bit-12mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
