With a 0.25-inch (6.35 mm) pilot diameter, it seats securely in the chuck pilot hole to deliver reliable torque without slipping. This type of key is a standard consumable and replacement item for trades and shop environments that rely on keyed chuck systems for consistent bit retention. Machinists, carpenters, electricians, and general tradespeople commonly keep a spare on hand due to the frequency with which chuck keys are misplaced or worn.\u003c\/p\u003e\n\u003cp\u003eThe JCM3605AP is intended for use with 0.25-inch and 0.375-inch Multi-Craft drill chucks. It suits both benchtop drill presses and handheld drill applications where a keyed chuck is installed. The KGA key number designation identifies the specific gear tooth and pilot geometry, making it important to match the key number to the chuck for proper engagement. This key weighs 0.45 pounds and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKGA key number for correct gear and pilot geometry engagement\u003c\/li\u003e\n  \u003cli\u003e0.25-inch (6.35 mm) pilot diameter for secure chuck pilot-hole fit\u003c\/li\u003e\n  \u003cli\u003eCompatible with both 0.25-inch and 0.375-inch Multi-Craft drill chucks\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.45 pounds for easy handling and storage\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for straightforward replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 0.25-inch and 0.375-inch Multi-Craft drill chucks requiring a KGA-pattern key with a 0.25-inch pilot diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert the pilot pin fully into the chuck pilot hole before engaging the gear teeth to avoid stripping the chuck ring.
