Infinity Tools 1/4 英吋柄 溝槽銑刀

I needed a bit to cut clean dados in plywood and this one leaves almost no tear-out even on the tricky veneer layers. The 1/4 inch shank held tight in my router collet with zero vibration during a full afternoon of work.

Got through a big pile of rough oak stock this weekend and it barely slowed down. The 1/4" shank held up perfectly for flattening and cutting clean dados, removed serious material without any burning.

Cutting through some thick cherry for cabinet dados and this bit handled it with zero burning or chatter. The carbide edges still look factory-sharp after a dozen passes. Just what I needed for serious stock removal.
