If you are purchasing this item because you want micro adjustment, save your cash. This knob is threaded onto a coarse threaded rod. In my world, the word micro means 'very small'. A fine threaded rod would have been better here. In my review of the router itself I mention this as well. Replace the threaded rod with a fine threaded rod. Buy a couple of nuts to fit it and a knurled knob. Bam... in comparison this would be a micro adjustment knob. Also, if you are using any taller bits, the micro adjustment knob has to be backed of so far that it comes off the top of the threaded rod. Where is the micro adjustment in this. For those of you using this a router for your table... I can imagine that a nut attached to a small fly handle would be better...faster adjusting any way. Of course you still have the coarse threaded rod to make those super fine adjustments.

I'm pleased with the ease the adjustment knob attached on my Hitachi M12V and with the way the knob allows fine adjustments. Use it with something like the General Tools 23 Aluminum Router Gauge or a drill bit (known diameter/height) to get the adjustments you want. However, if you are a bench top router table user be aware that this is one tall adjustment handle. You may have to set your table up on blocks or use it between to different benches to keep the adjustment handle from bottoming out.

This came with my Hiatchi M12V, which I got here at Amazon for a very reasonable price (Home Depot's price was $50 more!). I use this adjustment knob when the router is mounted in its table. I removed the plunge springs to keep them elastic. Although not a perfect system (raising all the way up takes a lot of rotations!), it definitely is better then trying to fight the springs with one hand and hold a square in the other!

WITHOUT IT, YOU WILL NOT BE ABLE TO MAKE FINE ADJUSTMENTS ON A ROUTER TABLE.

This knob is much better than the origional. The origional design is flawed. It broke by just setting down the router. You only move the router up and down a small amount and it works great for that.

I purchased this item, when it was offerd at the time I purchased my Hitachi M 12V, and spent an additional $25.00 plus shipping and handeling on it. Today I received my new router and found a very similar "Fine Adjustment Knob" in the box with the other attachments provided. I wish Amazon would not have suggested / offered this item seperatly, when it was already included in the package I was purchasing.

This product does not fit my router, although I was led to believe it would by the product description. It has no value to me.
