If using in a convential drill connection like a typical jacobs these hex shanks could possibly mount deeper and survive. But these cost more, and not really a cost effective option.
Ive had a dewalt 1/2 hammer drill, and don't recommend. The hammer function was lame and just trashed bits. This as you know is the main cost, masonsry bits.
I had a plain jane Milwaukee magnum 1/2" that would twisted my arms off, from 1988 to 2012 without a hickup one. I used this seriously and swear by this particular piece of equipment.
If their hammer model work excellent for a third of the time I would buy one.
The last two tools I needed "now" and replaced, got the winners choice of Bosch last year. These are both their top line models, I thought! especially for their cost. ( buy once cry once )
But importantly is again a choice considered a lifetime choice ha ha. Just as the before selections!
Although these have, and when first used had amazing qualities.
When holidays are past, I may look into this brand for a 1/2" hammer drill. Though honestly if these are lag/ concrete anchor size. It aint happening with these. Btdt
I now smartly rent a real tool with splined shaft and makes this job stupid easy, hell i can put in 2' long bits and rest on the job.
I can easily say hex drive drill bits, mounted in a quick connector as cordless impacts typically are. Have a bit more wobble. In my applications I consider this, and still I feel this is an important bit to you all.
ps: if anyone needs a 1" drive impact, with 1' extended shaft and weighs likely 35 lbs for your #6 brass screws give me a buzz. Your welcome to use the dolly to move it and the 5# sockets around
