Milwaukee Edge Guide Lock
Model Number: 43-98-0550
The Milwaukee 43-98-0550 is a genuine OEM Edge Guide Lock for the 6577-20 7-1/4 in. Worm Drive Circular Saw. This is the thumb-operated lock screw that clamps and holds the saw's edge guide, also called the rip guide or rip fence, at the desired position. The edge guide is the adjustable arm that slides into the saw's shoe and rides along the edge of the workpiece so the saw tracks a straight cut a set distance in from that edge, which is how a rip guide lets you make repeatable parallel rip cuts without snapping a chalk line. The edge guide lock is what secures the guide once it is set: threading the lock down clamps the guide arm firmly so it cannot slip or drift during the cut, and backing it off lets you slide the guide to a new width. Because the lock is a hand-operated part turned every time the guide is adjusted, and it sits exposed on the saw shoe, it is subject to wear, stripped threads, and loss. When the lock is stripped, damaged, or missing, the edge guide can no longer be held securely and rip cuts lose their accuracy. Replacing it with the correct genuine Milwaukee OEM lock restores a secure, repeatable edge guide setting.
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 edge guide lock 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. The edge guide itself and any related shoe and mounting hardware are separate parts that vary by tool, so refer to your tool's parts diagram for the correct companion part numbers and quantities.
