With a 120-degree point angle and a 0.125-inch cutting diameter, it is well suited for general-purpose spotting operations on a wide range of materials. The bright, uncoated finish maintains the carbide substrate at full hardness without any coating buildup that could alter the tip geometry. At 2 inches overall length, it is compact enough to run in tight setups while still providing adequate shank engagement in standard drill chucks and collets.\u003c\/p\u003e\n\u003cp\u003eThis spotting drill is intended for use on CNC machining centers, drill presses, and manual mills in job shop, production, and maintenance-repair environments. It performs spotting, countersinking prep, and chamfering tasks on steel, aluminum, cast iron, and similar workpiece materials. The single-ended, right-hand cutting configuration and straight cylindrical shank make it compatible with standard ER collet chucks, Jacobs-style chucks, and shrink-fit toolholders commonly found in metalworking operations. The 0.25-inch flute length keeps chip evacuation simple at the shallow depths typical of a spotting operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-degree point angle centers accurately and matches common twist drill geometries to minimize secondary burring\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance superior to high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish delivers consistent dimensional accuracy without coating-thickness variation at the tip\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design with right-hand cut for use in standard forward-rotating spindles\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits ER collets, Jacobs chucks, and shrink-fit holders without adapters\u003c\/li\u003e\n  \u003cli\u003eCompact 2-inch overall length suits low-clearance fixturing and short-reach tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose spotting drill suitable for use in standard drill chucks and collet systems that accept a 0.125-inch straight cylindrical shank.

Ensure the spindle is fully stopped and the machine is placed in a safe state before inserting or removing the tool from the chuck or collet. Seat the shank fully in the holder to the recommended grip depth and torque the collet nut or chuck key evenly to prevent runout. Avoid using this tool for deep drilling beyond its flute length, as it is designed strictly for shallow spotting and centering operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\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: 188\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC18808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51750759629106,"sku":"TC18808","price":38.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bd9c535331c55c1ecd5d74dcea0fe69.jpg?v=1788919461","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc18808-spotting-drill-1-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
