## Questions & Answers

**Q: I have a drill bit with a 10mm diameter shank that I want to fit in the end of the extension. Will it fit? What is the maximum diameter that will fit?**
A: The extension has a hex fitting. If you are using a 10mm spade bit this will have the appropriate end to fit. It will not hold standard drill bits unless you’ve got a hex set.

**Q: please, does this product fit an impact driver? And, does the female end fit the type of bit that would normally fit into the impact driver?**
A: The extension bit has a hex adapter on the male end so, yes, that will go into an impact gun and lock in place.  The female end is also a hex adapter to fit the Irwin stubby speedbore timber auger bits, which is what it's intended for.  You can fit a standard screw bit direct into the extension bar as it's the same size but it doesn't lock in place.  You could use an impact gun adapter to make the connection but I wouldn't think the Irwin extension would last long if used in an impact gun, it's not designed for anything other than a standard non hammer drilling action.

**Q: Will this fit bosch spade bits**
A: Yes all the bits have the same connection
