Premium MDF Wasteboard Sheet (3/4 inch, 24x24 inches)

$22

Overview

A flat, precision-ground 3/4-inch MDF sheet sized for CNC router wasteboards. MDF is the standard wasteboard material because it is flat, consistent, and easy to surface with a fly cutter. This sheet can be drilled for T-track inserts, threaded inserts, or used with the blue tape and CA glue method. Replace when the surface becomes too scarred from through-cuts.

Best for

Any CNC router owner who needs a fresh, flat wasteboard surface for accurate workholding
