Can’t go wrong with Jacob’s brand.
I use this tool everyday at work. And over 15 years i have had to buy three due to wear. Last time I got 2 extra as gifts to coworkers so they don’t have to barrow mine anymore !

Works well
The original chuck key had been damaged and was inoperable. The replacement chuck key worked just like it was intended. I would recommend this product for anyone who would need to replace their chuck key.

This Jacobs chuck-key, is the real thing', made by Jacobs in the USA. This size is for a fairly large 5/8" capacity drill chuck with a 3/8" inch pilot. It is obviously a quality American made tool . . .

I was given a drill press that didn't have a chuck wrench. It has a 3/4" chuck that would not fit this new chuck wrench (the hole in the chuck was too small) so I drilled out the chuck pivot hole so that this new chuck wrench will now fit and works well.
