I recently purchased the Dewalt DW318 SCMS and ordered this clamp at the same time. I was disappointed when I compared the clamp that came with the saw with this one. The stock clamp has a smaller knob on the top for tightening against the work piece, and only the DW7082 has the quick release button to quickly raise or lower it. The stock clamp does have a bolt on the back of the arm that can lower it on the leg, but the fence of the saw only allows 1/4" of play unless it's slid out of the way. Originally I only ordered one DW7082 clamp knowing that the saw would already come with a clamp, but after comparing the two side by side, I ordered a second DW7082 and put the stock clamp aside. To invest in the saw and not have accessories that perform the way I want them doesn't make sense to me.
