I am about to get started with using my Raw 1.5, but I am wondering what the maximum thickness endmill that can be used with the 1.5kw spindle? /Justin 5 December, 2017 at 11:03 #3352 JanneKeymaster First topic, nice 🙂 If you have the 1,5kw spindle then it can have 1-7mm end mills. I only cut with 3-4mm end mills and then clear surfaces with a 6mm end mill. You can also use bigger ones that has 6mm shaft. 5 December, 2017 at 14:14 #3353 Richard I have bought another Spindle. Also 1.5 KW 80mm diameter but with a 16mm collet. Problem (is there was any) solved. around 300 euro on eBay 5 December, 2017 at 14:34 #3355 JanneKeymaster yes there are ER11 up to ER20 collets so that you can have up to 20mm end mills, but for me its overkill i get by with 6mm and have done that for years… This reply was modified 1 month, 2 weeks ago by Janne. 5 January, 2018 at 00:25 #3707 JustinohlsenParticipant Awesome, and thank you for the information 🙂 Author Posts Viewing 5 posts - 1 through 5 (of 5 total) You must be logged in to reply to this topic.
