First, a diagram of the parts of a CNC end mill or router bit: Cutting Diameter is the width of cutting part of the tool. Flutes are the cutting edges along the side of the mill or bit. Length of Cut or "LOC "is the length of the cutting area. Overall Length or "OAL" is the length of the entire mill or bit. Slotdrills are the 2 flute cutters primarily used for milling keyways and slots. They can plunge downwards to depth in a drilling action. Slotdrills do not have a+ tolerance on diameter size so won"t ever cut oversize. Endmills, on the other hand can be 4, 6 or 8 flutes, generally for milling along 90' edges or finishing side walls.

One of the most important aspects of underground hard rock mining is ventilation.Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas). Switched to 11/16", (yeah, I was chicken...I only had a single 3/4" 2-flute end mill left!), and ran the slot full depth again. Then 3/4" and run the slot again. Cut the time in half (including tool changes) and burned up 0 end mills using the second method vs 3 for the first run (2 cheap china 4-flutes & 1 USA-made roughing 4-flute cobalt). 4900. I would first use a 5/16 end mill to cut a central slot clear through the part. From there, it depends on your tolerance for the slot width. Most 3/8 2 and 4 flute end mills will cut oversize slots. A 3 flute end mill will cut closer to the nominal size. If it is critical, use a sharp 5/16 end mill with cutting oil and take several passes.
