The Eco-Edge uses standard M10 router bits to create its edge.
With a 5/8-11 arbor, the Eco-Edge can be used with any standard polisher or grinder on the market.
China is the country of origin.
Weight of the package: 9.0 l.
With or without a router or polisher, Hardin ECOEDGE Variable Depth Router Edge Guide (HD-ECO) can be used to cut a variety of depths.
First and foremost, the results you can achieve with this router are extremely impressive, especially considering the price. To go along with this, I purchased the Hardin grinder, which I would not recommend. This was the most effective method for grinding with my $30 Skill 4 1/2 grinder.
The M10 female connections for router bits are the most difficult aspect of this router to work with. Due to the fact that I couldn’t find a single source for router bits that would work with this, I created an adapter out of a stainless bolt and an M10 to 5/8″-11 adapter that was readily available. I used a lathe to turn the bolt and a carbide bit to drill a hole through it to allow for water flow. After switching to the Skill grinder, it became clear that the water hole was a complete waste of time. It is sufficient to use only the adjustable squirt hose to direct a sufficient amount of water at the cutting surface.
It works well with diamond polishing pads, but it is too slow to work quickly with the grinding drum that I purchased from Amazon. The Skill grinder performed significantly better when spun at a faster rate.
In order to accommodate the profile bit that came with the Hardin polisher, I had to make yet another modification, this time by turning an adapter on the lathe. I may not have been able to complete this project without the use of a metal cutting lathe, but there are likely other profile bit sources that would fit and function just as well. In order to make this modification, I needed the router to recess the bit a little further than it was originally intended to. I created a spacer ring to raise the grinder mount another 1/2″ higher than it was originally.
I used standard woodworking saws and a router to cut templates out of 3/8″ Astek PVC sheet for this project. Then, by clamping these templates to my granite, I was able to use this router to cut out perfect shapes in the granite. I was even able to make a perfect 7-foot straight line cut by first making a rough cut and then finishing with this router against my PVC sheet, which was quite impressive.
Making a template makes it possible to create perfect curves as well.
The benefit of hindsigh. I would have paid the extra money and purchased the Makita polisher instead, because the Hardin polisher has numerous flaws that have been pointed out in the reviews. Even though a variable speed polisher is still required for polishing, a high speed grinder can be used to create this router’s smooth finish.
Given its low cost in comparison to every other granite router on the market, it is an excellent value. Its design issues can be resolved with a little bit of ingenuity. I think if they put a 5/8-11 chuck on it and increased the lift just a little bit, it would be absolutely perfect.
In addition, I would make the handle a little more comfortable. The orientation of the router is nearly perpendicular to the direction in which you are applying force to it. In some cases, working with it for a few hours at a time can cause pain in your hands’ palms as the shape of the handles becomes distorted.
