Overview
The Whiteside UD2102 compression bit combines upcut and downcut geometry in one tool. The bottom portion is an upcut spiral that pulls chips up, while the top portion is a downcut spiral that pushes chips down. This results in clean, tear-free edges on both the top and bottom faces of sheet goods. It is the gold standard for cutting plywood and veneered panels.
