To pre empt a few questions, along the lines of "can you make these wheels at 180,200 or 250mm" the answer is yes we can. But the chances are they would destroy the motor/axle of the machine to which they were attached.
We make these at 150mm for a reason. On a DW24000 that's the limit of adjustment to make them work.
These are not lightweight blades, they are quite a thick (substantial) profiling wheel which if we made at larger diameter would act as a flywheel and vibrate the machine to bits, they need to be this substantial to cope with the forces they are required to operate within which is not a cutting force but lateral stress.
If you have a large or volumous profiling job to complete, then ask what we can make or what we stock to make life easier. Something often exists already.
