Review on Niagara Cutter N61542 Uncoated Finishing Tool by Ted Higdem

I use this end mill in a 1/4" straight grinder to cut aluminum tools. It is a very smooth cutting end mill partly due to the high helical nature. It is very easy to work by hand and make very easy cuts If my hands were stronger I could probably make much deeper cuts while still being able to make a DOC of around 0.25-0.5mm and hand feed around 20mm/s .
