Techniks PowerCOAT ER Dust Seal NutsEdge of Arlington offers free shipping in the United States when you choose flat rate shipping. Use with our dust seal that snaps into the nut to seal and protect your collets and cutting tools. Match the ER collet size and shank size to the dust seal specifications. -40% more holding power than bearing nuts. PowerCOAT Nuts outperform bearing nuts!
PowerCOAT nuts greatly reduce friction between the nut, collet shoulder, and tool holder threads to increase down-force on the collet, collapsing tighter around the tool shank. This improves holding power and runout (T.I.R.). Better T.I.R. means cutting is faster and smoother, and tool life is also improved. ![]() |
