Like all of the SMW products I own ( fixture plate, modular vices and mitie bite ) are excellent and everything they are advertised to be. Highly recomend any of the SMW products.

Works well, low profile, may end up needing another set for a new vise

The Reversible Jaw Inserts and (Smooth/Serrated) for Modular Vise and Mudular Vise System (1/2") are excellent tools to use with our CMM. We look forward to purchasing other tools in the near future. Elizabeth Lobo Vice President/Director GPL Machine & Tool Inc. www.gplmachine.com

Great instructional video , well packaged , works nicely

Everything I would expect from SMW....excellent quality, fast shipping and follow up after the sale.

Great accessory, The only thing I recommend to improve it...its to make a small chamfer at the corners, to make space for a probe to set Z zero at the bottom face of the part

They make this CNC adventure painless by offering some awesome stuff to hold the parts down. Paul

Opposite sides are beautifully ground parallel to each other but sadly, are also both curved. Two thou off at center versus ends. Both jaws the same. Top and bottom appear to be spot on. The hobby mod’ vice is dead straight using same 0.01mm indicator. So that’s great. Overall very happy with the rest of the kit. :-)

I use the MOD VICE almost exclusively. This reversible jaw is very handy. I usually use the non-marring side but switch to the serrated side for extra security when surface finish isn't a issue. The relief added to the non marring side is a great improvement (not pictured). If you have the older version without the relief I would upgrade to these.
