Built from submicron-grade carbide and coated with TiAlN for heat and wear resistance, it measures 0.0827 inches in diameter with a 140-degree faceted point that reduces thrust and improves centering on entry. The overall length is 59 millimeters with a 4-millimeter straight-cylindrical shank. A web-thinned, tapered web configuration lowers cutting forces at the chisel edge. Spiral fluting evacuates chips efficiently at small diameters. This bit belongs to the Guhring Series 6400 and is intended for installation by machinists, tool and die makers, and CNC operators working with close-tolerance hole requirements.\u003c\/p\u003e\n\u003cp\u003eThe 9064000021000 is engineered for drilling cast iron, stainless steel, and steel as primary workpiece materials, and is also rated for aluminum and titanium alloy as secondary materials. Its 4xD flute-to-diameter ratio and 10-millimeter maximum drilling depth make it well suited for shallow, tight-tolerance holes in production and job-shop environments. Right-hand cutting direction is standard for conventional CNC and manual spindle setups. The 12.60-millimeter flute length provides adequate chip clearance for its rated depth. Diameter tolerance is held to plus 0.002 to plus 0.012 millimeters, consistent with reamed-fit or close-clearance hole requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for rigidity and edge retention at small diameters\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life in ferrous and high-temperature alloy materials\u003c\/li\u003e\n  \u003cli\u003e140-degree faceted point reduces walk and improves entry accuracy without a center drill\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers axial cutting forces at micro diameters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.002 to plus 0.012 millimeters supports close-fit hole applications\u003c\/li\u003e\n  \u003cli\u003eSeries 6400 spiral flute design optimized for short-depth, high-precision drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary workpiece materials cast iron, stainless steel, and steel (ISO material codes K, M, P) and secondary materials aluminum and titanium alloy (ISO codes N, S).

Secure the shank fully in a collet or precision drill chuck rated for the spindle speed required by the workpiece material and diameter. Ensure the machine spindle is fully stopped and locked out before changing or inspecting the bit. Avoid side loading or using this bit as a reamer, as carbide micro drills are brittle and will fracture under lateral force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0827 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 59.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 12.60 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 10.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.002 to plus 0.012 millimeters\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\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9064000021000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51733302575410,"sku":"9064000021000","price":138.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ec08b7d2d10f30efb963853f5958116.jpg?v=1788753837","url":"https:\/\/voomisupply.com\/products\/guhring-9064000021000-micro-drill-bit-0-0827-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
