Since you mentioned JIS previously, I had to go look it up, so I doubt any of mine meet that Japanese Industrial Standard. I do have a "pretty good" long tip that has served me well. (Probably why I over righted last time.) I did not push it when the screws resisted. I went to the manual impact driver which really did the trick after all these years, with a newer #2 tip. I do have a battery powered impact driver that I could have used to but wanted a little more finesse. Next time I buy tips/drivers, I will look at upgrading.
