SKU: 41940 Categories: , Brand:


Techniks 41940 Power Coat ER 40 collet nut, 63 mm x 26 mm.

Power COAT ER 40 Collet Nut Features:

  • ER40 collet 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

Power COAT 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.
