ER-TC Standad Rigid Tap Collets


Note:
Use with any standard ER, RD, DR, ESX or BR collet chucks for all rigid tapping jobs.
Special design locks flat-sided tap shanks into collet preventing the tap from spinning inside the collet.
For best results replace standard nut with a “Power Coat” nut to increase clamping pressure up to 75%.

Features

  • Metric sizes available upon request
