Built from submicron-grade carbide and coated with TiAlN, it delivers extended tool life in high-heat, abrasive cutting conditions. The 135-degree faceted point reduces thrust force and improves centering accuracy at entry. Through-coolant capability directs cutting fluid directly to the cutting edge, managing heat and chip evacuation in deep-hole operations. With an overall length of 62 millimeters and a flute length of 25 millimeters, this drill is sized for tight-clearance setups where standard-length drills cannot reach or fit.\u003c\/p\u003e\n\u003cp\u003eThis drill is engineered for production and maintenance machining environments where hole quality and dimensional accuracy are critical. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloy. The straight-cylindrical shank with a 4-millimeter shank diameter seats cleanly in collet chucks and precision drill chucks on CNC machining centers, VMCs, and drill presses. The 8xD flute-to-diameter ratio supports drilling to a maximum depth of 22.75 millimeters, making it suitable for through-holes and deeper blind-hole applications in production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides thermal barrier and extended cutting life at elevated spindle speeds\u003c\/li\u003e\n  \u003cli\u003e135-degree faceted point with web thinning reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers coolant directly to the cutting zone for chip control and heat management\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration maintains core strength while reducing cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry supports efficient chip evacuation in CNC and manual drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with cast iron, stainless steel, and carbon steel as primary workpiece materials, and aluminum and titanium alloy as secondary workpiece materials.

Ensure the machine spindle is fully stopped and the tool is properly torqued in a clean, undamaged collet or chuck before beginning any operation. Verify that the through-coolant circuit is active and delivering adequate flow before initiating a drilling cycle. Inspect the cutting edge for wear or chipping before each use, as micro drill bits operating at high feeds and speeds are sensitive to runout and improper fixturing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0886 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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\u003eOverall Length\u003c\/strong\u003e: 62 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 31 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 22.75 millimeters\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\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6408\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\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: 9064080022500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51746682700082,"sku":"9064080022500","price":261.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f340a5d0637159f49a00ab108f54f8c_feb60630-c001-4028-9f49-91b233704928.jpg?v=1788872644","url":"https:\/\/voomisupply.com\/products\/guhring-9064080022500-micro-drill-bit-0-0886-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
