This is the attachment every engraver needs to add to their system. SCM has designed a router attachment to give you complete control over the depth at which you are engraving. Simply place it onto the end of the PowerCarver and never worry about going to deep into your surface. This router base allows you to lock down the router at any desired depth with its set screws and also provides clear visibility with its two side view ports. Its perfect for doing inlay work, lettering, and borders. This will add an entire new dimension to your engraving!
