Milwaukee Inner Blade Flange
Model Number: 43-34-0275
The Milwaukee 43-34-0275 is a genuine OEM Inner Blade Flange for the 6577-20 7-1/4 in. Worm Drive Circular Saw. The inner blade flange is the metal disc that sits on the spindle between the blade and the saw body, acting as the backing plate that supports the inner face of the saw blade while the outer flange and blade bolt clamp the blade from the opposite side. The correct mounting sequence is the inner blade flange on the spindle first, then the 7-1/4 in. blade, then the outer flange, and finally the blade bolt tightened with a wrench, so the blade is sandwiched between the flat, machined faces of the two flanges and held concentrically on the saw's 5/8 in. spindle. That flat, stable backing is what keeps the blade running true, which on a powerful 15-amp worm drive saw is essential to clean, straight, accurate cuts and to safe operation under load. Because the inner flange provides the reference face the blade seats against, a flange that is worn, bent, warped, or damaged can no longer support the blade flatly, allowing the blade to run out-of-true, wobble, or lose secure clamping, which is both a cut-quality problem and a serious safety hazard. Replacing a damaged inner flange with the correct genuine Milwaukee OEM part restores proper blade support and secure retention.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. This inner blade flange is specified for the 6577-20 7-1/4 in. Worm Drive Circular Saw, so confirm your tool's catalog and serial number against the parts diagram before ordering. A wrench is required to remove the blade bolt when replacing the flange. The outer blade flange, blade bolt, and saw blade are companion parts sold separately, so when replacing the inner flange, inspect the outer flange and blade bolt at the same time and replace them if worn or damaged, since these parts work together to retain the blade.
