It features a 100-degree point angle and a 0.250-inch cutting diameter, making it well suited for creating shallow, precise conical seats that guide twist drills and reduce walking. The two-flute spiral configuration and bright uncoated finish are optimized for general-purpose cutting applications. With a 2.5-inch overall length and a 0.250-inch straight cylindrical shank, this tool fits standard drill chucks and collet systems used on CNC machining centers, knee mills, and drill presses.\u003c\/p\u003e\u003cp\u003eThis spotting drill is intended for general-purpose machining environments in job shops, production facilities, and toolroom applications. It is a single-ended tool ground from solid carbide for consistent geometry and rigidity. The 100-degree point angle is a common choice when spotting for standard twist drills, as it creates a seat angle that centers the following drill without inducing runout. The 0.750-inch flute length provides adequate chip clearance in shallow spotting passes. Machinists and CNC operators working with steel, aluminum, and similar engineering materials will find this tool appropriate for typical production spotting cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree drill point angle for accurate centering ahead of standard twist drill operations\u003c\/li\u003e\n\u003cli\u003e0.250-inch cutting diameter with matching 0.250-inch straight cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity, wear resistance, and consistent geometry\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design promotes chip evacuation during spotting passes\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose cutting across common engineering materials\u003c\/li\u003e\n\u003cli\u003e2.5-inch overall length compatible with standard toolholding setups on CNC and manual machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill for use in standard 0.250-inch collets, drill chucks, and toolholders on CNC machining centers, vertical mills, and drill presses where a straight cylindrical shank is accepted.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist familiar with proper toolholding practices. Ensure the machine spindle is fully stopped and the tool is secured with the correct collet or chuck before beginning any operation. Verify runout at the shank before production use, as excessive runout will reduce spotting accuracy and shorten tool life. Follow the machine manufacturer and applicable shop safety guidelines when setting speeds and feeds for solid carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 100 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: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eTool Application\u003c\/strong\u003e: Spotting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 pounds\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: SPD-250-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52021478687026,"sku":"SPD-250-100","price":55.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b76f1a111104df8a612ea02ee3e5b8e.jpg?v=1790012538","url":"https:\/\/voomisupply.com\/products\/micro-100-spd-250-100-spotting-drill-0-250-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
