With an 8 mm cutting diameter, an 82-degree point angle, and a 3.11-inch overall length, this tool is built for accuracy in general-purpose metal cutting applications. The cobalt M-42 substrate provides heat resistance and hardness retention that outperforms standard HSS tooling in tougher materials. A bright, uncoated finish is standard. The right-hand spiral flute geometry promotes clean chip evacuation from the start. This drill is typically installed and used by machinists, tool-and-die professionals, and maintenance technicians working with metalworking machines.\u003c\/p\u003e\u003cp\u003eThis spotting drill is suited for use on drill presses, CNC machining centers, and manual mills where accurate hole location is required before transitioning to a twist drill or reamer. The 8 mm straight cylindrical shank fits standard ER collets and drill chucks without modification. With a 25 mm flute length and a 20-degree helix angle, the tool performs reliably on steel, stainless, cast iron, and similar ferrous workpiece materials under general-purpose cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree point angle for accurate drill starts and countersink alignment\u003c\/li\u003e\n\u003cli\u003eCobalt M-42 construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e8 mm straight cylindrical shank fits standard collet and drill chuck setups\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral geometry promotes chip clearance during spotting operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 20-degree helix angle for controlled entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids on ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill compatible with standard 8 mm straight-shank tool holders, ER collet chucks, and keyless drill chucks on drill presses, manual mills, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the straight cylindrical shank in a properly sized collet or drill chuck and verify runout before use. Power down and lock out the machine before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life.
