It accepts bit shanks from 3\/64 inch (0.059 inch) up to 1\/2 inch (0.500 inch), making it suitable for a wide range of drill bit sizes used in trade and production environments. The chuck uses a plain bearing design and is constructed from steel for durability under repeated use. Tightening is performed with the included K34 key. The 1\/2-20 threaded mount is a common spindle interface found on drill presses and portable drilling equipment. This chuck is installed by machinists, tool-and-die technicians, and maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis chuck fits drilling applications in light manufacturing, maintenance, and shop environments where a threaded-mount keyed chuck is required. The 1\/2-20 thread size is a standard interface on many benchtop and floor-standing drill presses as well as some portable drilling equipment. The 3\/64 to 1\/2 inch capacity range covers the majority of twist drill and step drill shank sizes used in everyday trade work. The steel construction and plain bearing design make it a straightforward replacement or spare for production and maintenance shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCapacity range of 3\/64 inch to 1\/2 inch accommodates most common drill bit shank sizes\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 threaded mount for direct spindle installation without an adapter arbor\u003c\/li\u003e\n  \u003cli\u003eKeyed operation with included K34 chuck key for positive bit clamping\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body construction for shop-duty durability\u003c\/li\u003e\n  \u003cli\u003e43 mm sleeve diameter with a closed length of approximately 2.87 inches and open length of approximately 2.32 inches\u003c\/li\u003e\n  \u003cli\u003ePlain bearing design for straightforward maintenance and reliable operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-threaded replacement chuck for drill presses and drilling equipment with a 1\/2-20 spindle thread.
