Great Product and Service 6/29/2018

I bought a bit holder set several years ago and after finally breaking the last insert I couldnt figure which insert would fit my holders. Sent an email to customer service and in short order i was told what I needed and was able to order replacements. Shipping was fast. Great service thank you


I enjoy have access to Grizzly for purchasing items like this. But...I really wish you offered a better insert. They're an ok product at best. I wouldn't mind paying more if I had to for a better product.
Thank you
Michael Webb
