Review on FTG USA Improved Adjustable Countersink by David Elam

Just what I needed to replace the original cone cutter for my broken countersink. Countersinking with this tapered center drill works wonders. I particularly like how it leaves a central hole for easy screwing, especially in those tricky spots where you fasten 2 pieces of wood together. I used this to build my chicken coop and it was great to be able to countersink the screws without splitting the boards. This allowed me to fill all the holes with putty and sealant to keep the bolts from rusting from the weather and salty air as I live on the South Jersey Shore. 6 months have passed and everything is like the first day!
