Different-size drill chucks require different-size keys, so finding the right chuck key for your drill is the key to secure, optimal tightening of your bits. A properly fitted key seats cleanly in the chuck and lets you snug the jaws down without slipping.
Great Lakes Power Tools carries Milwaukee chuck keys and key holders in a range of sizes to fit Milwaukee drills. The holders let you attach the key to your cord or tool so it's always within reach and never lost. Whether you're replacing a missing key or adding a holder to keep it handy, there's an option here to match your drill.
