Built to Series 6412 specifications, it features a 135-degree faceted point angle with web thinning for accurate entry and reduced thrust force. The TiAlN coating provides thermal resistance and extended tool life in high-speed cutting environments. At 0.0748 inches in diameter with a total length of 70 millimeters, this drill is designed for machinists and toolroom professionals working with tight-tolerance bores requiring consistent hole quality in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for CNC machining centers, drilling cells, and manual machine tools where small-diameter, high-precision bores are required. Primary workpiece materials include cast iron, stainless steel, and steel. It also performs in secondary applications involving aluminum and titanium alloys. The through-coolant design makes it effective in deep-hole micro drilling operations where chip evacuation and heat management are critical. It is a right-hand cut tool with a straight-cylindrical shank, compatible with standard collets and tool holders sized for a 4 millimeter shank.\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 for high-heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree faceted point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability supports chip evacuation in depths up to 32.10 millimeters\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h7 diameter tolerance for precise tool holder fit\u003c\/li\u003e\n  \u003cli\u003e15xD flute-to-diameter ratio supports deep micro-drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet-style tool holders accepting a 4 millimeter straight-cylindrical shank.

Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Through-coolant connections should be verified and coolant flow confirmed before starting the cut. Do not exceed the rated maximum drilling depth of 32.10 millimeters without retracting for chip clearing unless the machine cycle is programmed for pecking.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0748 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\u003ePoint Type\u003c\/strong\u003e: Faceted\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: 70.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 32.10 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\u003eShank Length\u003c\/strong\u003e: 33.00 millimeters\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\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: 9064120019000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734277718322,"sku":"9064120019000","price":290.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb0e6fa4ae5c2f6de48ba61ef36e2ae4_42041015-1e27-431a-8c7c-aa3b8bd9bc8d.jpg?v=1788762149","url":"https:\/\/voomisupply.com\/products\/guhring-9064120019000-micro-drill-bit-0-0748-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
