I drive #14 pan head screws into oak floors. The Snappy carbide tipped countersink stayed sharp after countersinking 45 bolt holes. I recommend this tact! Works perfectly.
Well made and exceeds all expectations. Very sharp and perfect countersunk holes for screws. The first use was in Hard Aged Maple and went without any problems. Happy with my purchase.
This countersink is great, cuts straight into the surface with very little separation and the drill stays sharp. This will certainly save you money in the long run. You can also change the bit afterwards, the hard metal stays sharp for a long time.
