On web and on our catalog there are charts full of informations. Suggested materials, suggested uses, speeds and feeds.
The speed of taps, reamers, twist drills and mill cutters is meter/minute (for machine tools). To convert m/min into rpm use: m/min*1000/(ø*3,14)
Reamers feed is m/min.
Mill cutters feed is mm/tooth.
Feed of mill cutters, reamers and twist drills depends on: materials being machined, the material the cutter is made from, the economical life of the cutter. We suggest you to keep updated on our blog, online catalog, on line tech support and printed catalog.
