Too weak. Deformation at higher speeds. makes convex holes. The thin drill actually flexes instead of drills when you press on the drill. continued to get stuck in moderately softer woods. The only good thing was that I needed them for 1 job so I didn't have to worry if they would last. That's not what you want. Keep searching.
