Review on Ingersoll 9512 Hammer Change Retainer by Michael Crossman

A much better way to use a pneumatic hammer than a cheap spring bit holder. This makes it very easy to change bits and feels a lot more secure. Updated on 08/26/2016. The first suggestion was my first impression when I bought this device. Now after owning and using it for several years I am changing my 5 star rating to 1 star. It turned out to be scrap - very poorly finished. Any chisel I use in it immediately gets stuck as soon as I try to use it. It then requires considerable effort to remove the bit from the holder. I had to go back to the original spring bit holder which works great and ends up being more efficient because the bits don't get caught in it.
