Whiteside UD1602 1/8-inch compression spiral
1/4 in

When to choose it
The UD1602 offers a fine 1/8-inch cut with both upcut and downcut flute sections. It is an option when you are comparing edge quality on both faces of plywood and want a narrower groove than a quarter-inch cutter makes.
Check how the two flute sections contact the actual stock. This model’s half-inch cutting length is useful for comparison, while the permitted pass and machine setup come from the manufacturer’s instructions.
