Review on 🔧 Ideashop Countersink Adjustable Professional Aluminum: Perfect Precision for Flawless Sinking by Tyler Dorsey

I was pleased with the result of using Ideashop countersink bits. I tested it with a 3/16 bit in very hard white oak. The drill worked smoothly and produced a clean countersink. Once the drill reaches the thick part, it tends to pull, probably due to the drill's wide, long flutes. The countersink was reasonably clean with a few small burrs on the edge of the countersink. The Grip-Rite #6 glass slotted screw is ideal for countersinking. I really like the 2 hex head screws that hold the bit in place and this combined with the flat surface means the countersink will never slip off. The pointed tip makes it easier to start drilling.
