Cobalt high-speed steel construction provides increased heat resistance and hardness compared to standard HSS bits, making it suited for drilling hard and abrasive materials including stainless steel, cast iron, titanium, and hardened alloys. The stub-length body offers a shorter flute and overall length than a jobber-length bit, delivering greater rigidity and reduced deflection in production drilling and repair applications. This bit is used by machinists, pipefitters, ironworkers, and maintenance trades needing repeatable hole quality in tough materials.\u003c\/p\u003e\n\u003cp\u003eThe C1090-056-I is appropriate for use in drill presses, milling machines, and hand-held power drills equipped with a 1\/2-inch chuck. Its screw machine length geometry makes it well suited for close-clearance work and CNC fixture applications where shorter tool stick-out reduces chatter. Typical applications include drilling through-holes in structural steel, pipe flanges, equipment frames, and heavy plate in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-inch cutting diameter in a stub screw machine length profile for added rigidity\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction resists heat buildup during high-feed or dry drilling\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank fits standard 1\/2-inch drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eSuited for drilling hard ferrous metals, stainless steel, and abrasive alloys\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 — available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt stub drill compatible with any drill press, CNC machine, or hand-held drill equipped with a 1\/2-inch or larger chuck capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with metalworking drill safety. Secure the workpiece firmly before drilling and use appropriate cutting fluid or coolant when drilling hard alloys to extend tool life. Inspect the bit for chipping or wear before each use.
