It features a 7\/32 inch (0.220 inch decimal) pilot diameter, which corresponds to 5.55 millimeters. The key engages the chuck body to tighten or loosen the jaws during bit changes. Machined to OEM specifications, it provides a secure, properly fitted interface with the chuck socket, reducing slippage and wear during repeated use. Licensed electricians, HVAC technicians, and general trades professionals routinely keep chuck keys on hand as standard shop and field tooling.\u003c\/p\u003e\n\u003cp\u003eThis chuck key is suited for bench drill presses, floor-standing drill presses, and handheld drill equipment that accept the K7 key pattern with a 7\/32 inch pilot. It is commonly used in manufacturing, fabrication, HVAC ductwork shops, plumbing shops, and electrical panel rooms where keyed drill chucks remain in regular service. The JCM3659P is sold individually and is a direct-fit replacement for worn or lost original equipment chuck keys on JACOBS 7 Series chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK7 key number for compatibility with JACOBS 7 Series chuck bodies\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch (0.220 inch) pilot diameter for a precise, snug fit in the chuck pilot hole\u003c\/li\u003e\n  \u003cli\u003ePilot diameter equivalent of 5.55 millimeters for reference when matching metric specifications\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.07 pounds, making it easy to store and handle\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit, allowing replacement of individual lost or damaged keys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with JACOBS 7 Series drill chucks requiring a K7 key with a 7\/32 inch pilot diameter.
