Grizzly Industrial H5608 - V-Block Pair w/Clamps 1-5/8"

My application is a lot different than most people's. I'm using these in a laser lab to hold laser rods for testing. They'll do just fine for this. I noticed a lot of people have complained about the poor quality of the clamps that are included. I think they beefed them up in the interim, because the set I received appear to be quite heavy and stout. They're made from cast iron/steel with a 3/8(?) 8mm(?) SHCS for the bolt. Everything is heavily coated in cosmoline or similar material for rust prevention. I'm not too concerned about parallelism or flatness but they appear adequate. Considering a similar sized set from McMaster-Carr would run $300 and up, I'll take these!

These arrived in excellent condition and are the perfect size for my mini mill (7" x 27" table/ 4" vise). All surfaces are nicely ground and there are no rough or sharp edges. They are well matched as a pair.

V-blocks are great for the money and for small hobby mills. The clamps are trash.

Works well for the use, I've always had good luck with Grizzly products including larger metal working and wood working equipment.

Very nice and sturdy little clamping blocks

I was somewhat concerned when purchasing these as some of the other reviewers have complained that they are not match ground. For all intents and purposes mine are perfect. I inspected them on the surface plate and they are as precisely matched to each other as I can possibly measure. Haven't tested the clamps yet but they seem to be made better than some of the cast clamps you see in the v-blocks in this price range.

V-blocks themselves are pretty accurate. Did have some light surface rust that took some scotchbrite to clean up. The clamps leave something to be desired. Threading is sloppy. One clamp has the hole drilled off axis so you have to be very careful that the work piece dosen’t move when tightening the clamp.

Much smaller than you can imagine. Horse shoe and main screw are very light weight. Horse shoe anchored by T-slots on top is a better design then side anchor slots. Poor tolerance casting and machining will cause anchor failure. A c-clamp is in your future. Perhaps ok for holding wood or plastic. Not for serious work.
