Tool Holders

PowerCoat Ultra High Speed ER Nuts

•40% more holding than bearing nuts
•Balanced to 25,000 RPM
•Better rigidity and T.I.R. (runout)

PowerCOAT nuts greatly reduce friction between the nut, collet shoulder, and toolholder threads to increase down force on the collet, making it collapse tighter around the tool shank. This improves holding power and runout (T.I.R.). Better T.I.R. means cutting is fast- er and smoother and tool life is improved.
