3/8″ 邊槽銑刀 × 1/2″ 刀柄 – Whiteside 1901

I was cutting some cabinet panels and this bit produced a perfectly clean, consistent rabbet without any chipping. The 1/2 inch shank felt rock solid in the router, and the depth stop ring held its setting even after several passes.

The shank is solid and true; I didn't feel a hint of vibration even on some gnarly grain. Popped out a clean L-shaped notch in one pass and the edge was surprisingly crisp.

This bit cut a perfect 3/8″ rabbet on my first try, and the 1/2″ shank ran smoothly in my router table with zero vibration. Exactly what I needed for making cabinet backs fit flush.
