Review on INGCO 21Pcs Titanium Drill AKDL52101 by Ronny Welch

Good bits in M2 alloy steel with titanium nitride coating. The large drill bits are sharpened on both sides at the base for a better grip in the drill chuck, which is a nice feature. I also like the pilot point on the big beats. I just received them so I can't confirm durability. A minor thing, but the storage case is so-so, especially for small items that don't hold tight enough. Unfortunately, the small plastic retaining clips break easily; One was broken when received, presumably due to the plastic wrapping of the bits inside the case, which is good but a bit odd. In addition, the holder inserts do not tilt forward to facilitate nozzle removal, as is the case in some cases. The case will NOT stop me from buying Beats, but the manufacturer should look at other cases and improve on their own.
