The cobalt construction provides heat resistance and edge retention when drilling through hard materials such as stainless steel, cast iron, hardened alloys, and high-tensile metals. The stub length geometry offers greater rigidity than a standard jobber drill, reducing deflection and improving hole accuracy in tight or shallow-clearance setups. This bit is suited for machinists, pipefitters, and fabricators working with drill presses, magnetic drills, or heavy-duty hand drills equipped with a 1\/2-inch chuck.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in metalworking and fabrication settings where hole diameter precision and bit durability are critical. The 61\/64-inch diameter is commonly used when preparing holes for tapping, reaming, or close-tolerance fastener fitment. The 1\/2-inch shank makes it compatible with standard 1\/2-inch chucks on drill presses and hand drills. It is appropriate for both production shop use and field service work where cobalt performance is needed over standard high-speed steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e61\/64-inch cutting diameter for close-tolerance drilling applications\u003c\/li\u003e\n\u003cli\u003eCobalt construction delivers superior heat and wear resistance compared to standard HSS bits\u003c\/li\u003e\n\u003cli\u003eStub length body provides added rigidity and reduced deflection in shallow drilling setups\u003c\/li\u003e\n\u003cli\u003e1\/2-inch reduced shank fits standard 1\/2-inch drill press and hand drill chucks\u003c\/li\u003e\n\u003cli\u003eSuitable for stainless steel, cast iron, hardened alloys, and other hard metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any drill press, magnetic drill, or hand drill equipped with a 1\/2-inch chuck.
