Need a new chuck for your cordless drill? This is a 3/8-inch (13mm) double sleeve drill chuck that's compatible with a ton of popular 18V battery-powered tools from brands like Bosch, Makita, and Panasonic. It's an unbranded/generic part, but it's built to do the job. The double sleeve design usually means easier and tighter bit changes. It comes brand new in its packaging. Perfect if your old chuck is wobbling, won't grip bits right, or just stripped out. Makes your drill feel new again. Just make sure your drill's thread matches up. A simple, affordable fix instead of buying a whole new tool. Great for DIYers and pros alike.
