With a 140-degree drill point angle and a 0.375-inch cutting diameter, it establishes precise spot locations that minimize walking and promote true hole entry. The two-flute spiral geometry and web-thinned construction reduce thrust requirements and promote clean chip evacuation. This tool is built for high-performance applications where positioning accuracy directly impacts hole quality and downstream operations.\u003c\/p\u003e\u003cp\u003eThe QSPD-375-140 is suited for use in CNC machining centers and manual mills across job shops, production facilities, and precision manufacturing environments. Machinists and CNC operators use spotting drills like this one as a first-operation tool before full drilling, countersinking, or tapping. The Micro-Quik shank design is specific to MICRO 100 quick-change tooling systems, making it a direct fit for compatible holders in that system. The bright uncoated finish is appropriate for a wide range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e140-degree drill point angle for accurate spotting and reduced radial thrust\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral geometry with web thinning to lower cutting forces and improve chip flow\u003c\/li\u003e\n\u003cli\u003eMicro-Quik shank for use with MICRO 100 quick-change tooling holders\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose spotting applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, single-ended design for standard CNC and manual spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with MICRO 100 Micro-Quik quick-change tooling holders; the QSPD series is a MICRO 100 proprietary shank interface and requires a compatible holder from that system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state. Secure the Micro-Quik shank in the appropriate quick-change holder according to the holder manufacturer's torque and engagement specifications. Verify runout with a dial indicator before starting production cuts. Spotting drills operate at higher speeds and lower feeds than twist drills; consult MICRO 100 cutting data for recommended surface footage and feed rates for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Micro-Quik\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thickness\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QSPD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MICRO 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QSPD-375-140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52016871080242,"sku":"QSPD-375-140","price":89.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b54e51ac27eeed00830ad588de319e3.jpg?v=1790008978","url":"https:\/\/voomisupply.com\/products\/micro-100-qspd-375-140-spotting-drill-3-8-in-140-deg-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
