This has 1-7mm, and I already have 8mm, so I now literally can use ANY metric bit up to the biggest size you can stuff into an ER11 collet. They even came individually packaged, and the icing on the cake is the whole set is less than $20!!! 5 stars and what a great value. Review: Nice set of bit holders to assure you always have the correct one - Each collet came individually packaged and labeled in an extruded plastic box with cover. All were made the same as the CNC 3018 Pro I bought them for. They grip properly and individually hold a wide variety of small bits. ## Features - ➤7Pcs ER11 Collet Set Gripping Range: 1mm to 7mm (1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm) - ➤Made of formulated spring steel. - ➤Perfect for CNC milling lathe tool and work-holding engraving machine.
