The drill bits are made in Dewalts german drill bit plant “BBW Bayrische Bohrerwerke”. Also the regular pilot point drill bits and some concrete drill bits.

I am aware that Hitachi, Makita, and possible others offer impact drill bits. BUT, and that’s a big but, those bits are all 2-piece bits, and they appear as if the bits themselves are standard and only the hex bits are impact rated.

It looks as if these are the first bits for which the cutting flutes are impact rated as well.

Testing the bits in a standard drill is a good idea – we will definitely incorporate that into the planned testing procedure, thanks!

I know Hitachi aslo makes impact ready stuff, that includes drill bits. However, I am unsure of who else makes hole saws. I believe Milwaukee might as well (can’t remember now, too late), as I was looking at their impact stuff at the borg the other day.

One thing to test amongst those who use them, try the bits in a drill as well as the impact driver. I found the bits heat up more in the impact driver, and I end up with a slightly larger (wobbly) hole. Just my experience. Thanks for the site!
