I'm only a DIY round home bloke learning as I go, but I got one of these Ti15 Impact drivers just recently to upgrade my old drill and got it as I plan to have a roofing and deck job ahead, and after reading the first statement, was concerned about drill bits coming loose and falling out, so thought I'd give it a tryout, since we have the 30day right of return and all. My observation so far, all is well and good on that. Whew. In fact I tested an old 25mm spade drill bit and put it into the Ti15's standard jacobs chuck, "locks" in place far better than my old c12 drill. (With that drill funnily enough I did have issues locking bits in and sometimes they came loose-similar to one of those videos on this sight where one falls out). I really like the feel of the bits being securely clamped in, a more positive feel for me with it. I dont feel its all that big a chuck, yes a bit longer than the c12s chuck but not a deal breaker for myself.
I tried drilling multiple holes in 50mm hardwood and the bit stayed put securely and tight in the Ti15. I then tried various sized drill bits and all locked in and stayed in place no problem even a 2mm bit. So on that score, I feel it is a major improvement on my C12 drill. Seems to have a heck of alot more power than the old c12 on the older style batteries). I haven't test it on anything thicker yet but think 50mm or less is most of the things I'm likely to do anyway.
Next I tried the centronic drill bits directly inserted and they also worked well so no complaints there from me. I didnt try using the extra chucks though so I'll try that tonight. They do seem cumbersome in length when added to the "non-impact" attachment but at least gives the benefit of being able to use them as I have them from the c12 kit.
I've only used an impact driver on a couple of odd jobs on a friends house some time ago, but obviously since this drill can do impact drilling, it's really a new experience for me to get used to the noise and "impacting" whilst driving in screws. I see I'm gonna need some practice as I find it a little awkward holding the screw in place and then trying slowly to get the screw taking hold then letting go and giving it full power, bloody quick but I found drives not as straight as using a standard drill and pushing down. Seems I may push the drill at a slight angle so the heads are sitting proud on a angle. Maybe thats an experience thing and I'll get better with use. I hope so. Perhaps I should also have pre-drilled a pilot hole and even counter sunk for the tests? I was lazy and just thought I'd impact a few screws into timber to see how it works. So a little learning required for me I think.
Regarding power, I've used plenty of various drills from tiny to big heavy 18v and powered hammer drills. This Ti15 seems to drill darn fast and not have that annoying twisting of the wrist that some drills do when you start. I hate that! so again I'm happy it has plenty of power and not that twisting wrench. It does seem noisy when impacting screws and I wondered at first what the heck was that noise?-du-oh, but as I said, I'm not really familiar with what other impacters sound like so can't compare so I have to assume they all are noisy at least to some degree. Maybe I should have simply gotten a T15 or C15 but thought having the extra "impact" available gives me a more useful all-round drill that compliments the c12 I already have. And of course can share the various chucks and drills so thats sweet. I suppose it'll get a more thorough test out when I extend my deck soon, $ permitting. Be nice to have both drills at hand loaded, one for drilling and the other for driving screws, rather than only one and chopping and changing bits all the time-tedious. I'm looking forward to giving it a more thorough workout ahead. As I say, I'm not a contractor so don't know what to expect or what tests I should put it through, but find it drills really well, and drives with plenty of grunt. One thing I do dislike is a common design placement of the switch from forward to reverse, being left handed I knock this and sometimes set the darn thing in reverse! annoying but after years of using multiple drills with this layout you'd think I'd be more careful. Why cant the switch be on top? Curse of being a lefty.
Thanks for all the input on this site by-the-way, love it.
