With a 1.70 mm (0.0669 inches) diameter and a 135-degree split-point geometry, it starts on contact without a center punch and reduces thrust force. The IchAda coating improves wear resistance and extends tool life in ferrous and non-ferrous materials. Overall length is 60.00 mm with a 17.00 mm flute length and a 3.00 mm straight-cylindrical shank. Coolant-through capability supports chip evacuation during deep-hole drilling. This bit weighs 0.01 pounds and is suited for CNC machining centers and precision drill presses.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is used in precision manufacturing applications including aerospace, medical device, electronics, and general metalworking. Its small diameter and rigid carbide construction make it appropriate for tight-tolerance hole drilling in steel, stainless, aluminum, and similar workpiece materials. The right-hand cutting direction is standard for conventional spindle rotation. Machinists and tool-and-die professionals working with close-tolerance prints will find the 135-degree point geometry reduces walking and improves positional accuracy without a pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.70 mm (0.0669 inches) diameter with 135-degree drill point angle for self-centering entry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003eIchAda coating extends tool life and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole and high-speed drilling\u003c\/li\u003e\n  \u003cli\u003e3.00 mm straight-cylindrical shank fits standard collet and drill chuck toolholding\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for conventional CNC and manual spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and precision drill presses equipped with collet systems or drill chucks accepting a 3.00 mm straight-cylindrical shank. Verify spindle runout and toolholder concentricity before use at micro diameters.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove this bit with the machine fully powered down and the spindle at rest. Use a collet or precision drill chuck sized for the 3.00 mm shank to minimize runout; excessive runout at micro diameters accelerates breakage. Confirm coolant-through lines are clear and pressure is appropriate for the material before initiating the drilling cycle. Handle carbide tooling carefully to avoid chipping the cutting edges during setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.70 mm (0.0669 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: IchAda\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 17.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.6 x 0.5 x 0.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8732031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738479427890,"sku":"8732031","price":171.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/687a81421e1d14570a1fe43e19a04b12.jpg?v=1788800086","url":"https:\/\/voomisupply.com\/products\/osg-8732031-micro-drill-bit-1-70mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
