## Questions & Answers

**Q: What's the warranty length on bestgle 1.5-13mm capacity 1/2-20unf mount impact drill chuck with 1/2" square female socket adapter?**
A: I used it once and the adapter striped out so I wasn’t happy

**Q: Which size do I buy for a 3/8 impact dewalt wrench**
A: 3/8

**Q: Can this be use on the bosch bulldog?**
A: This adapter is not the same I bought for my application. I bought a 1/4" quick disconnect from impact guns to be used with a 1/2 chuck adapter. This one seems to have a slip and lock SDS adapter. If your power tool don't have this adapter, most likely should not be used as it will be damaged by improper usage.

**Q: What is the diameter of the shaft? I want to use this for a flex shaft rotary tool with a 3/16" chuck**
A: This is only to use for sds plus systems

### ⭐⭐⭐⭐⭐ Gets the job done

Gets the job done but will wobble a bit when used on an impact driver not for precise work. I keep this with my dewalt 1/2" impact in case.
