Cobalt construction provides elevated heat resistance compared to standard high-speed steel, making it well suited for drilling through harder materials such as stainless steel, cast iron, and hardened alloys. The stub-length body offers increased rigidity and reduced deflection, which improves hole accuracy in production and maintenance drilling applications. This bit is imported and designed for use in stationary drill presses and heavy-duty portable drills fitted with a 1\/2-inch chuck.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is appropriate for metalworking applications in commercial, industrial, and maintenance settings. Electricians, pipefitters, millwrights, and general maintenance technicians commonly use screw machine drill bits where rigidity and cutting performance in ferrous metals are required. The 1\/2-inch shank allows direct chucking in standard 1\/2-inch drill presses and handheld power drills without the need for a reducer sleeve.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt alloy construction for improved heat resistance and tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch cutting diameter for common structural and mechanical drilling tasks\u003c\/li\u003e\n  \u003cli\u003eStub-length (screw machine) body increases rigidity and reduces bit deflection\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight shank compatible with standard 1\/2-inch chucks\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any drill press or heavy-duty power drill equipped with a 1\/2-inch or larger chuck.
