Milwaukee Inner Blade Flange
Model Number: 43-34-0815
The Milwaukee 43-34-0815 Inner Blade Flange is a genuine OEM replacement part designed for the Milwaukee 2734-20 M18 FUEL 10 in. Dual Bevel Sliding Compound Miter Saw, and may fit additional Milwaukee miter saws in the same product family. The inner blade flange is the precision-machined metal disc that fits on the saw arbor between the saw spindle and the saw blade, centering the blade against the spindle shoulder and providing the flat reference surface that the blade rests against during cutting. The inner flange works in conjunction with the matching outer blade flange (Milwaukee 43-34-0810) and the blade arbor bolt to clamp the saw blade securely between the two flanges, transferring rotational drive from the spindle to the blade and ensuring concentric, vibration-free blade rotation across the saw's full RPM range. The inner flange surfaces are critical to dimensional precision and runout accuracy, so any wear, deformation, corrosion, or contamination of the flange affects cut quality immediately.
A worn, scored, bent, corroded, or damaged inner blade flange can cause blade wobble, increased vibration during cuts, premature blade wear, inaccurate miter and bevel cuts, or in severe cases, blade loosening during operation - all of which compromise both cut quality and operator safety. Replacing the flange with this OEM service part restores correct blade centering, proper clamping geometry, and accurate cut tracking. The 43-34-0815 is paired with the matching Milwaukee 43-34-0810 Outer Blade Flange, which is sold separately and is often replaced at the same time when both flanges show similar wear. Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee 2734-20 service parts diagram before ordering, since Milwaukee uses several different inner blade flange part numbers across their miter saw lineup (including 43-34-0680, 43-34-0865, and 43-34-0132) and the 43-34-0815 is specific to the platforms it serves. Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment for your specific miter saw.
