Product Description
Milwaukee 1/4 in. Chuck Key
Model Number: 48-66-3200
The Milwaukee 48-66-3200 is a 1/4 in. Chuck Key — the correct replacement chuck key for Milwaukee 1/4 in. capacity keyed drill chucks on Milwaukee drills and drill presses equipped with a 1/4 in. keyed chuck. The chuck key is the operating tool required for all bit changes on keyed chuck designs — it is used to engage the chuck's key boss and rotate the chuck to tighten or loosen the jaws for bit installation and removal. Without the correct chuck key, a keyed chuck cannot be properly tightened to secure the bit for drilling or loosened to release the bit after the drilling operation — making the chuck key as essential to the tool's operation as the drill itself. Milwaukee specifies this chuck key for chucks 48-66-0070 and 48-66-0104, and compatible 1/4 in. capacity Milwaukee keyed chucks that use the same key geometry.
Chuck keys are small accessories that are easily misplaced on busy jobsites and in shop environments where tools and accessories are frequently moved between locations — a missing chuck key puts the tool out of service for bit changes until the key is found or replaced. Having a replacement on hand prevents this avoidable tool downtime. The chuck key must match the chuck's key boss diameter (the circular gear that the key's pinion engages) and the pilot pin diameter (the pin that locates the key in the chuck's pilot holes before tightening). Using an incorrectly sized chuck key produces poor gear engagement that makes tightening difficult, risks damage to the chuck's key boss, and produces inconsistent jaw tightening that allows bit slippage during drilling.
Always verify that the replacement chuck key matches your specific Milwaukee chuck model number — chuck key sizes are not universal and an incorrect size will not engage properly with the chuck's drive mechanism.
