The rear guide block maintains the blade’s position in the correct cutting plane by providing a backing contact point just behind the blade teeth without this rear support, the blade would flex backward under the cutting resistance of the material being cut, producing curved, inaccurate cuts and potentially accelerating blade fatigue from the bending stress of unsupported cutting. The rear guide block assembly is a wear item that experiences progressive wear from the continuous contact with the moving blade throughout production band saw use as the guide block material wears, blade support degrades and cut accuracy decreases.Using a genuine Milwaukee OEM rear guide block assembly ensures the correct block material, dimensions, and mounting geometry for the specific Milwaukee band saw model the rear guide block’s contact geometry must be precisely correct for the blade width and thickness it supports, and incorrect block dimensions either fail to support the blade adequately or create excessive friction that slows the blade and accelerates wear.
