Built to Series 6412 specifications, it features a 1\/16 inch (0.0625 inch) diameter, a 135-degree faceted point angle, and a TiAlN coating that extends tool life when cutting hard and abrasive materials. The through-coolant design channels cutting fluid directly to the tip, reducing heat buildup and chip evacuation issues during deep-hole operations. The shank is straight-cylindrical with an h7 diameter tolerance, and the web is thinned to reduce entry force and improve centering accuracy. This bit is installed by machinists and tool-and-die professionals working on CNC machining centers and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in ferrous and non-ferrous machining environments including job shops, production facilities, and maintenance-repair-overhaul operations. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloy. The 15xD flute-by-diameter ratio and 27.41 mm maximum drilling depth make it appropriate for deep micro-hole applications where chip clearance and coolant delivery are critical. Right-hand cutting direction is standard for conventional spindle rotation on CNC and manual drill equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating reduces thermal wear and extends tool life in ferrous and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability directs fluid to the cutting zone for deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree faceted point with web thinning reduces thrust force and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h7 tolerance ensures consistent chuck or collet grip\u003c\/li\u003e\n  \u003cli\u003e15xD flute ratio supports chip evacuation in deep micro-hole operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement and production micro drill bit for CNC machining centers and drill presses requiring a 1\/16 inch straight-cylindrical shank tool with through-coolant capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. The straight-cylindrical shank requires a precision collet or chuck rated for the 4 mm shank diameter. Verify coolant system pressure is compatible with the through-coolant path before operation to prevent blockage or insufficient flow at the cutting tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 29 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 27.41 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 33 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\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\u003eDiameter Tolerance\u003c\/strong\u003e: h7\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\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 9064120015900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51733052850482,"sku":"9064120015900","price":264.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb0e6fa4ae5c2f6de48ba61ef36e2ae4_200609ea-f927-4027-a33d-482039f91aec.jpg?v=1788750972","url":"https:\/\/voomisupply.com\/products\/guhring-9064120015900-micro-drill-bit-1-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
