Review on Wolfride Straight Router 4 Inch Double: Unleashing Precision and Double Cutting Power by Rickey Ortega

Very sharp and an absolute steal compared to big store prices. I actually bought them for the CNC not knowing they are straight and can't cut. So if you want to drill a hole in the middle of something, it won't work. Straight cuts cannot "pierce" the material but will burn a hole as they lack the helical whorls that a regular drill would have. For this you need an upcut spiral or a downcut spiral, however with some modifications and tweaks you can make this tree EAT with CNC if its contours and they go through the side.
