Milwaukee 4-1/2 in. Type 1 Guard Assembly
Model Number: 43-54-0920
The Milwaukee 43-54-0920 is a genuine OEM Type 1 Guard Assembly replacement for compatible Milwaukee 4-1/2 in. angle grinders — the mandatory wheel guard that must be installed at all times during angle grinder operation with Type 1 straight wheels and cut-off wheels. The wheel guard is a required safety component — it shields the operator from wheel fragments, sparks, and debris ejected during grinding and cutting at operating RPM, and provides containment in the event of abrasive wheel breakage. A cracked, deformed, or missing guard requires removing the grinder from service immediately — the tool must not be operated without the correct guard installed. The Type 1 designation specifies that this guard is designed for Type 1 flat wheels used at 90° to the wheel axis, as opposed to Type 27 depressed-center wheels which require a different guard profile.
Milwaukee manufactures this guard to the correct dimensional specifications for the specific 4-1/2 in. grinder model's guard mounting collar — a guard with incorrect dimensions would not mount securely on the grinder's guard mounting boss or would not provide adequate wheel coverage for the 4-1/2 in. wheel diameter. Always verify your specific Milwaukee 4-1/2 in. angle grinder model number and serial number at milwaukeetool.com before ordering replacement guard components, as guard specifications vary between Milwaukee grinder models and production revisions.
