Hi JT,
Although the quality of some products seems to be fluid because of the quality/price trade-off caused by inflation.
I've been happy so far I have been using and am happy with the Makita Impact XPS bits. Mine have a titanium nitride coating.
The Milwaukee Shockwave bits have always been considered a top of the line product. If I didn't already have a lifetime supply of Maktia bits I would likely buy Milwaukee.
A few years ago, Project Farm did a review of several brands of screwdriver bits. Makita and Whia bits were always in the group of best performers in their testing. (Makita bits did pretty good as well and so did Bosch.
I'm curious to hear what others have to say so I will be following your thread!
Dave
