Review on 🔝 Optimized Timberline 608 114 Release Countersink with Enhanced Diameter by Joshua Flame

I have used high speed steel countersinks on the oak furniture I make. HSS wears out after 100 holes. I've used these carbide countersinks for over 1000 holes and haven't noticed any wear. However, carbide is brittle and will chip if you hit metal (another screw or a broken drill bit). You just have to be careful and they last forever.
