Genuine DeWalt lower blade guard — part 618231-00 — replacement lower guard assembly designed for 305 mm saw blades; it restores the lower blade coverage and guard action on compatible DeWalt mitre saws.

Fits a range of DW700-series machines such as DW716 and DW718 (multiple Type / XPS variants are listed), including DW716E and DW716EXPS/DW718XPS configurations where this lower guard is specified.

The unit is the molded lower guard assembly (guard, spring and mounting plate arrangement) that replaces a broken or worn lower shield so the blade is properly covered when the saw arm is raised — restoring safe operation per the tool’s parts diagrams and safety guidance. It’s listed among DeWalt parts for the DW716/DW718 series.

Simple to swap in with the original mounting points; ordered as part number 618231-00 and intended as a direct-fit genuine DeWalt replacement to get your saw back to service.
