EANOSIC Upcut Spiral Router Bits 1/4 inch Shank, 1/4 inch Cutting Diameter Solid Carbide with Nano Blue Coating CNC Router Bits End Mill for Wood Cut, Carving, Edge Trimming

This carbide bit has mirror-like ground surfaces. Its amazingly sharp, enough that you need to be careful when handling it. Deep spiral flutes for amazing chip removal. Center cutting, so you can plunge with it. Side cuts are extremely smooth. Like most center cutting bits, the bottom of a slot is not shiny smooth like side cuts, but is perfectly flat with sharp corners. Comes in a standard industrial type bit box for protection.

This bit is especially good at plunge-cutting dadoes quickly and cleanly. Its an upcut bit, meaning that it pulls the chips OUT of the groove instead of pushing them down inside, where they can slow cutting action. Weve not used this bit on a router table so far, but similar upcut bits are especially useful on a table because they actually pull the work down slightly, and help keep the piece tight to the table. Cant comment on the longevity of the bit because we havent had it that long, but no reason to think it wont last for quite awhile before needing sharpening. Recommended.

This is a really good router bit. I used it in my plunge router with good results - a clean, straight groove. The price is great too.

Ive used several different EANOSIC bits and they have all been of consistent quality. This is no exception, it works well in ash and other hardwoods both on a standard router as well as a Shaper Origin for which upcut bits work the best. The coating seems to make at least a little difference in reducing burning compared to no coating, but I might be imagining this.

Super cutters. I stick to this supplier now, the end mills last long on plastics and wood. I do only light jobs on aluminum, they work on aluminum too.
