HSS Step Reamers
Step reamers should be ran at 1/2 the R.P.M. suggested for a corresponding twist drill size. Coolant feeding reamers: Coolant or cutting tool lubricant induced thru the reamer should be utilitized when possible. Benefits include better finishes, superior tool life and the ability to increase speeds and feeds. All tools are constructed with left-hand spiral and right-hand cut. The left-hand spiral eliminates the tendency of the reamer to pull itself into the holes.
