Works as advertised
I've had the 1/8" kerf model for several years and it's yet to break or fail. Recently, while ripping some white oak, I did run into some internal tension but by dropping a thin shim wedge into the kerf after the splitter, the offcut side of the boards did not bind the blade.

What a nice solution to burning and esp. to the wandering away from the fence that can happen to the fence-side piece of a long cut on a narrow board. Hint: Before installing the splitter, be sure your zero clearance insert is perfectly adjusted (seated snuggly in the insert opening) so that it will never need to be readjusted (and possibly moved) after the splitter is installed.

I too have been using my table saw without a splitter since I changed to using thin kerf blades. This not only greatly reduces the risk, but also prevents burn marks at a very low cost. It is an easy addition. I strongly recommend this device.

I had just tuned up my tablesaw and, then installed this splitter per the easy to follow instructions. It works as designed and I no longer burn maple when ripping long pieces. Well worth the low price.

This is an ingeneous little piece of safety equipment, and probably the best $[] upgrade you can do for a table saw. I'd been using my table saw without a splitter for years because the blade guard was so awkward, but this gives me some measure of safety against kickback without any interference. I've already recommended it to every friend with a table saw.

I've been using the 1/8"splitter #37477 for a little more than a year. It worked fine until last week when it got pinched by a piece of yellowheart, pulled out of the mounting holes, and one of the pins broke off. I emailed Micro Jig and found that replacement polycarbonate splitters can be ordered directly from Micro Jig. I called, ordered two sets, and they arrived by first class mail two days later. No shipping charge. This is a good product but one should expect to have to replace the splitters once in a while.

Although made from plastic, the installation jig allows for very percise fitting and is particularly effective in shop made zero tollerance throat plates. When used correctly, it is highly effective and has worked well for me.One warning - be sure to match the splitter product to your blade kerf. There are three different sizes made. Check out the Microjig web site for details.

Cannot be used with existing blade guards that already have splitter/anti-kickback cleats.
Perhaps I would not have purchased this device if I had realized that it only works whenever the factory blade guard and its integral splitter/anti-kickback tangs have been removed. The only time I cut without a factory guard is when I'm running very thin stock or when cutting dadoes. Basically, this device is a waste of money and waste of time required to drill the mounting holes in your zero clearance insert(s).

Can I change the thin and thick splitters when I change blades or do I need to buy both?
A C on Dec 7, 2019
BEST ANSWER: I got both. The thin kerf won't keep the workpiece from pinching a standard blade, and the standard kerf will hang up as the workpiece comes off the thin blade.
Will this jig work on small table ( potable table saw) ?
Dusty on Jul 16, 2016
BEST ANSWER: As long as there is a removable table insert (and it can be drilled), I don't see why there would be any reason it wouldn't work. I'd suggest looking at the product pictures to make sure you have the proper clearance behind the splitter on your table. It has been a while since I installed mine, so I'm going off my memory of the installation instructions; however, I can't think of anything that would preclude it. Was there something that stuck out in your mind that you thought might be an issue?
What is the difference & benefit between the MJ Spitter & MJ Splitter Steel Pro?
Mark P on May 5, 2018
BEST ANSWER: The MJ Steel Pro Splitter has a stainless core and the MJ Splitter does not. They both do the same thing.
Can this be used on a Jet table saw?
Chuck B on Apr 4, 2017
BEST ANSWER: I dont have a JET but as long as you can drill in the throat plate behind the blade - yes. Make sure you are getting the right size to match your blade thickness. It comes with super clear setup instructions.
I have the 1/8" one in green and like it. But now I want the thin one. I thought it was in yellow ?
John D on Oct 4, 2015
BEST ANSWER: It comes in several colors, depending on the model you purchase. (Yellow, green, blue, and orange)
