SE - Pin Vise Set, 4 Pc - 846PV

I bought to hold my tungsten rod to grid, when they came contaminated.

I bought these for doing watch repair/modification, and for holding small parts for grinding and polishing. I already have a proper setup for drilling small precision holes so I don't need these to be chucked up in a drill press using a 1/2 inch chuck, or even a hand drill chuck. So, not sure what the runout of these things are, but given the price I wouldn't expect them to be dead-nuts accurate, ya know what I mean?For my intended purpose, these work very well. I can hold very small screws and pins and with enough force to perform file work and grinding on very small pieces. I have also been able to chuck up a small drill bit to clean up already driled holes and to slightly enlarge drilled holes in order to properly fit pins by hand.They are substantially built, which is nice. They feel heavy-duty and not cheap. However, they do need some cleaning up as they are shipped with a heavy coating of a cosmoline-type lubricant. Personally, I liked that as I was sure that there was no corrosion in areas I could not see. They also need a little de-burring with a small file in the jaw area, but we're not talking Starret, we're talking about something that your interested in because you don't want to pay those prices.So, you wouldn't be looking at these if you wanted a "for sure" high-quality pin vise. You're here because you're hoping that these "cheaper" pin vises will do what you need them to do without costing an arm and a leg. For me, they more than sufficed. I needed them to hold small pins and screws for grinding and polishing. If you're wanting some sort of adapter solution for powered drilling where you really should be using the proper tooling, then you're probably going to be betting on a hit or miss situation where some of these may work, and others may not.In any case, I'm giving this product 5 stars because of the price point, and that more than satisfied my requirements.

I am glad I found these here for the price, which is terrific. I bought these to use in HO train modeling and I could not have asked for a better product for the price. The package includes all sizes I need. Very heavily greased as two others mentioned-necessary to clean with a rag before using. I can understand why, it keeps rust off the metal. Add grease to the threads as mentioned and these babies will work for you for a long time! I like the handles are hollow and can except things like coping saw blades.Great product-recommend!**Have to add this; It is now February 16, 2016 and I have to replace the one that is size 1.3mm-3.1mm because it is no longer holding bits straight. Disappointed as up until this time, it had been working well but noticed holes were no longer straight. On closer observation, found this was the reason. The other 3 pin vises still work fine. **As of 3/5/16, the largest one also no longer holds bits straight, so I have gone ahead and ordered the General Tools one, that takes large size bits and has the black, screwdriver like handle. Wish me luck ;) I did find a substitute pin vise to replace the defective 1.3mm-3.1mm size one. It has a swivel head, is nickel plated and is made in India. They have them here, even though that is not where I bought it; SE #840SH. Actually holds bits and taps straight!

For the price, I can't complain too much. However...The smaller two vices are near-useless. The collet is cut offset from center, and does not have a centering bevel. The few bits you can manage to jam into the collet will sit off-center and slightly askew. Given the size and shape, it may be possible to replace the collet in the two smaller vices with nylon slugs and hand-cut the clamp slots. As they stand "out of the box" they are useless garbage.The two larger vices are spot-on, and work perfectly. The collet slots are centered, reasonably clean from burrs (not perfect, but 'good enough'), and have centering bevels drilled into the center. Worked fantastically for 2mm-3.5mm bits. I really appreciate the flared design of the knurled grip section where it joins the collet - made it extremely comfortable to wield and use to ream out clogged passages.If you need some pin vices for >1mm drill bits, then this set should do really well after cleaning off the rank tool oil and re-oiling with something that doesn't smell like rotten gym socks (3-in-1 or mineral oil work great).If you need pin vices for micro-fine bits (.15mm up to .95mm), look elsewhere. You're just going to get frustrated. If you're willing to re-machine collets for the two smaller vices, then you'll find them just as functional as their bigger brothers. However, if you're willing to go that route, you're wasting time and money on something you could have already made yourself - just do it right from the word 'go'.Splitting the difference: 5 stars for the two larger vices, 1 star for the two smaller, averaging it out to 3 stars for the set

They work as I require

Kind of cheaply made

Quick delivery. Will work well for my numbered bits.

Not the best quality

works ok not great
