The reason it only accepts 1/4" tools is probably because it doesn't have enough torque for 1/2" ones. If you need to run 1/2" diameter tooling, get a bigger spindle.
oky ty sir
More info needed. What kind of spindle do you have? for example if you have a 2.2Kw with an ER 20 then you can accept half inch bits you will have to get an ER20 1/2'' colletQuote:

ER11 only will accept a max tool shank size of .276 or 7mm. You will need to either find some larger bits with quarter inch shafts which i really dont recommend or get you a new spindle that's at least ER20 so you can hold 1/2 inch shaft toolsQuote:

thats why i want the ER20 so i can put different size bits in and some one told me that will be to heavy i was looking into one looking for options looking at hitachi routor
