Axminster ER20 Precision Collets

These end mill collets have the unique ability to grip over a diameter range of 1mm without any loss of accuracy. This flexibility means that fewer collets need to be stocked, making them a more economical proposition when compared to other collet-based systems. An additional benefit is that there is no requirement for a separate imperial listing; a 1/4" end mill, for example, will fit into the 7.00mm to 6.00mm collet. Our range covers the ER20, ER25 and ER32 sizes together with their respective morse taper or R8 holders. Collet nuts are available separately, ideal for customers wishing to make their own holding devices or spindles. ER20 and ER25 collet holders have M10 threads and the ER32 has an M12 thread.
