Milwaukee Inner Flange
Model Number: 43-34-0091
The Milwaukee 43-34-0091 is a genuine OEM Inner Flange replacement for compatible Milwaukee circular saws or cut-off tools — the precision-machined inner clamping flange that is mounted on the arbor as the fixed contact face against the inside of the blade's center bore. The inner flange and the outer flange together sandwich and clamp the saw or cut-off blade between them when the arbor nut is tightened — the inner flange's contact face contacts the inner face of the blade, and the two flanges' concentric, flat contact faces must be parallel and perpendicular to the arbor axis for the blade to be clamped concentrically without runout. The inner flange's arbor bore, outer diameter, and contact face flatness are all precision specifications that determine blade concentricity and clamping load distribution during high-speed saw operation.
When the inner flange becomes damaged from tool drops, deformed from over-torquing the arbor nut, or contaminated with debris that prevents flat seating against the blade face, the blade develops excessive runout that degrades cut quality and can create safety concerns at operating speed. Replacing a damaged inner flange with a genuine Milwaukee OEM component restores the correct contact face flatness and arbor dimensional fit for concentric, evenly-clamped blade installation. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com before ordering replacement flange components, as inner flange specifications vary between Milwaukee saw models and blade diameter configurations.
