Measuring 1\/32 inch (0.0312 inches) in diameter with an overall length of 1.5 inches, this bit features a 130-degree split point angle that reduces walking and improves entry accuracy. The spiral flute geometry promotes efficient chip evacuation during drilling. Right-hand cut direction is standard for use with conventional drill presses, CNC machines, and handheld drilling equipment. The bright, uncoated finish makes it well suited for non-ferrous metals, plastics, composites, and other materials where coating buildup could be a concern. Machinists, toolmakers, and precision fabricators are the primary users of this bit.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is intended for applications where small-diameter hole accuracy is critical. Typical uses include PCB drilling, instrument component manufacturing, watchmaking, jewelry fabrication, and fine metalwork. The 1\/8-inch shank diameter allows it to seat securely in standard collet chucks and drill chuck systems commonly found in benchtop and CNC drilling setups. The 0.395-inch flute length provides adequate chip clearance for shallow-to-moderate depth holes at this diameter. This bit is sold individually and is appropriate for both production shop environments and single-piece precision work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at micro diameters\u003c\/li\u003e\n\u003cli\u003e130-degree point angle reduces drill walk and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eSpiral flute design promotes chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous metals, plastics, and composites\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for use with standard drilling equipment and CNC machines\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard collet and drill chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC drilling machines, drill presses, and precision handheld equipment equipped with collet or drill chucks accepting a 1\/8-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by machinists or trained fabricators familiar with micro-diameter tooling. Ensure the spindle and workpiece are fully secured before starting the machine. Micro drill bits are brittle at small diameters — avoid lateral loading, excessive feed pressure, or unsupported workpiece movement, as these conditions commonly cause breakage. Always verify spindle runout is within tolerance before running micro-diameter tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/32 inch (0.0312 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.395 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732074463538,"sku":"20250","price":32.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45484e9865a76a31bb8dc0d15db6b00e_5ec26f59-37cd-47e0-8103-6d85605d9585.jpg?v=1788738917","url":"https:\/\/voomisupply.com\/products\/harvey-tool-20250-micro-drill-bit-1-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
