It accepts drill bits and round-shank tooling from 1\/16 inch up to 1\/2 inch capacity, covering the full range of common drill bit sizes used in metalworking, woodworking, and general fabrication. The chuck body is constructed from steel and uses a ball bearing mechanism for smooth, consistent jaw actuation. With a sleeve diameter of 43 millimeters and a closed length of approximately 2.93 inches, this chuck is sized for benchtop and handheld drill applications where a compact, reliable clamping solution is needed. An M6 screw is included for installation.\u003c\/p\u003e\n\u003cp\u003eThis chuck is suited for use on drill presses, handheld power drills, and similar rotating equipment with a 1\/2-20 threaded spindle. It is appropriate for light industrial, maintenance, and shop applications across trades including machining, mechanical, and general construction. The keyless design allows for hand-tightening and quick bit changes without a chuck key, which is an advantage in production or service environments where speed and convenience matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKeyless operation for fast, tool-free bit changes\u003c\/li\u003e\n  \u003cli\u003eCapacity range of 1\/16 inch to 1\/2 inch accommodates most standard drill bits\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 threaded mount for compatibility with standard drill spindles\u003c\/li\u003e\n  \u003cli\u003eBall bearing design for smooth jaw movement and consistent clamping force\u003c\/li\u003e\n  \u003cli\u003eSteel chuck body for durability in shop and field use\u003c\/li\u003e\n  \u003cli\u003eIncludes M6 screw for mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or upgrade keyless drill chuck for drill presses and handheld drills equipped with a 1\/2-20 threaded spindle mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician or machinist with the drill or drill press fully powered down and unplugged before beginning.
