Milwaukee's 18 ga. Shear model 6850 features a swivel head that contains a center blade (48-44-0150), a left blade (48-44-0160) and a right blade (48-44-0170). Each blade is replaceable separately, but it is recommended to change all three at the same time for maximum sharpness. This style shear removes a continuous metal curl approximately 1/4 inch wide.
