Super sharp, no tear out
I purchased and used this yesterday. Going slow as recommended by positive reviewers, I am extremely happy with this tool. It cuts very fast and I had no tear out. I even used it on one blank that I forgot to trim before turning! It does not fit a 7mm reamer (dumb), but 11/64 (I think that's what it was) is close enough.
Whiteside Carbide Cutter
Won't work for 7MM blanks. Leaves the brass tube proud. I recommend disc sanding first and trimming the 7MM blanks with the steel cutter. Looks like they would have stayed this in the product description.
Terrible. Bits get stuck.
This trimmer works great until you have to change out one of the bits. I have the 7 mm and the size 0. Whenever I took out the 7 mm bit and swapped it for the size 0, I had a hard time getting the 7 mm bit out, I didn't think anything of it so I went ahead and installed the size 0. I used it several times and then I went back to put the 7 mm bit back in, it literally was almost impossible to get the bit out. even with the set screw completely removed the bit was stuck in there so hard I had to use a hammer and a punch to remove it. I can't believe I wasted my money on this barrel trimmer and the two bits I bought to go with it. I could have saved all that money and just bought a cheap one off Amazon. Lesson learned.
Good sharp cutter, but a couple downsides
First off, it stays sharper longer than the 4 blade cutter. The carbide chews through anything easily. Downsides: 1 - it likes to dig in, so if you're using a drill press or hand drill, you may end up destroying some blanks. Chucking it in the lathe and using the tailstock handwheel prevents this. 2 - the cutter teeth do not go all the way to the mandrel shaft. No issue with bigger sizes, but it won't fully trim the brass on a 7mm insert for a slimline-type pen.
Agree with everyone else here about 4 blades versus 2, but, if you take your time, it works fantastic. I have destroyed blanks being overly aggressive, or just plain not paying attention. One of the better quality products I have purchased for pen making.
Cuts excellent with a caveat.
This cutter-head works really well if you use a tool that allows you to provide slow and even pressure. Originally I used it in my hand drill as I did with the HSS version (which I also like) and I found it was really easy to be over-aggressive in wood, and in acrylic I was getting chipping on top of it. Now I trim my blanks on the lathe the same way I drill my holes. The slow advance of a lathe tailstock allows this to effortlessly make clean shaves as it trims flush, with no chipping and not accidentally shortening your tubes.
will not fit the older woodriver mill set
Stays Sharp, Destroys Blanks
I thought that having carbide tips would be great as it would not have to be sharpened as often. But only having two teeth it tends to grab and break the blanks. I think that I've destroyed as many blanks as I've successfully milled. I'd consider purchasing one with four teeth but would not buy another one of these.
This is very strong and very impressive/aggressive. My problem is that it will catch on the end and tear out a bit of the work piece. If there were 3 or 4 teeth instead of just 2 it would last and be a fantastic product without so much damage.
I wanted a trimmer that would stay sharp longer than the carbon steel ones. I was a little skeptical about only two wings for cutting. I have used this on over 200 acrylic and wood pens so far and this is still cutting like new. It does make a slight scallop if I push too hard when trimming the end of the blank but I sand flush after turning. I would like it better if it had 4 cutters even thought it would be more expensive. With 4 cutters it should be a top quality item.
