Milwaukee Double-Ended Power Bits

Milwaukee Introduces Double-Ended Power Bits

Double-Ended Power BitsA couple months ago we attended the Milwaukee Tool New Product Symposium 2016. Towards the end of our rotation we came to the accessories room. Usually, the accessories are not that glamorous at media events. This year was a little different, Milwaukee was really showing off its carbide Sawzall blades and the HoleDozers with the new coating that doesn’t turn soft when it heats up. Off on a side table though, they were showing off some new double-ended power bits that had different tips on each end.

A lot of companies make double ended power bits but many put the same tip on each end. For the life of me I can’t figure out why one would need one that had PH2 on both ends. The tips that caught my eye at the table were ones with PH2 and T25 combos. As a self-performing general I use both of these types of fasteners a lot. Previously I was carrying around a small case with the bits I used most often so that I could switch out the tips when necessary. Sometimes I’d carry another bit on the little holder on the side of the impact but we all know that’s a good way to lose bits.

Just seeing the new double-ended power bits I knew I had to have one. Being the last rotation of the day and having a few dozen of the bits on hand, the product manager let me take one home with me. The next day we had it out on the jobsite putting it to work.

Besides the convenience factor of having two bits in the impact at once, what makes Milwaukee’s version of the double-ended power bit a worthy investment is that it is also a quality bit. After two months of constant use and abuse there isn’t much for wear short of the black coating wearing off where the bit interfaces with fasteners. All of the nitty gritty details of the metallurgy of what makes the bits great are explained in the press release below but what I can tell you is that they can take a beating and are crazy convenient.

The only thing I’d like to suggest to Milwaukee is to add a SQ1/SQ2 combo and a SQ2/T25 combo. Oh and add some colored stripes like they have for their nut drivers (or like the GRK Torx bits) so that a bit end can be easily identified. The T20/T25 bit would probably benefit the most from having colored stripes on the end.

    I’d like it if the “double end power bits” were magnetic. If that was possible.

    1. Jeff Williams

      Other sites are reporting that they are magnetized, the one I have is currently but it is pretty weak. I’m not sure if it was always that way or if it was because I store it next to the magnetic bit holders in the bit case. I’ll update the post when we receive some production bits.
