The Grizzly G0750G and the PM 1236 appear to be almost identical machines to me. The Griz has a D1-5 cam lock and the PM 1236 uses the smaller D1-4. The PM 1236 stand comes with a brake and coolant system. The Griz has a spider on the outboard of the spindle and its tail stock has a 1/2" square drive available to use a torque wrench on. Other than that everything else seems quite similar. Are Grizzly Build Specifications a higher standard than the PM 1236 or is it a wash?
