Ridiculous Machine Tools Collets RT632 Editorial Review
The ER20 ULTRA Precision Spring Collets have been receiving positive customer feedback. Customers have used this product with CNC machines and lathes, and have found them to be of great quality and precision, with negligible runout. They are also easy to install and remove from the collet nut. However, there have been complaints from one customer about the edges protruding too much and being too sharp, suggesting a defect in quality control against a .0002-inch tolerance. Comparatively, the reviewer recommends Techniks .0002 collets.
