Manufactured from Cobalt M-35 (HSS-E) material, this single-ended drill delivers improved heat and wear resistance compared to standard high-speed steel. The cutting diameter measures 0.5000 inches, with an overall length of 6.75 inches and a bright, uncoated finish. The web-thinned geometry reduces thrust forces at the cutting tip, supporting accurate spot placement before through-drilling. This tool is intended for use by machinists, tool-and-die technicians, and maintenance tradespeople working with drill presses, lathes, or CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis spotting drill is suited for general-purpose metal drilling operations in shop and field environments. It is commonly used to establish a precise starting point for twist drills, preventing bit walk on flat or angled workpiece surfaces. The right-hand cutting direction and spiral flute design make it compatible with standard right-hand spindle equipment. Applications include production machining, fabrication shops, and maintenance facilities working in steel, stainless steel, cast iron, and other ferrous materials where cobalt tooling is appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt M-35 (HSS-E) construction for enhanced heat and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e90-degree drill point angle for accurate spotting and chamfering\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tip reduces cutting thrust and improves centering accuracy\u003c\/li\u003e\n\u003cli\u003eSpiral flute design with 2 flutes promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose ferrous metal applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for use in standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill compatible with standard drill presses, lathes, and CNC machining centers equipped with a 1\/2 inch capacity chuck or collet accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the spindle is fully stopped and de-energized before loading or removing the tool from the chuck or collet. Confirm the shank is fully seated and properly clamped before operation.
