Techniks 46140 Power Coat ER 40 ultra high-speed slot nut, 63 mm x 26 mm.

Techniks 46140 ER 40 collet nut Power COAT features

  • ER40 high speed slot nut
  • 40% more holding than bearing nuts
  • Balanced to 25,000 RPM
  • Better rigidity and T.I.R. (runout)
  • Use with Techniks 04617 ER-40 wrench, sold separately

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 faster and smoother and tool life is improved.
