Difference between milling cutter and reamer
Bottom edge milling cutter, reamer is generally not. The edge of the milling cutter is relatively sharp, and the reamer is usually straight and not sharp.
The reamer has a certain taper, but the pattern of the reamer is vertical ~ the knife end is relatively flat,The pattern of the milling cutter is spiral, with a sharp blade in the cross section
Besides they say, the most intuitive is that the blade part of machine reamer is very short, while the neck is very long, so it looks like a long dumbbell.The end mills have longer cutter teeth, accounting for 1/2~2/3 of the overall length of the tool, and the neck is short. The cutter tooth is spiral and has fewer teeth. It looks sharp.People who don't know much about knives do so.
