Review on 🔧 IRWIN SPEEDBOR 341008 8-Piece Groove Bits Set by Lild Zimmerly

Very sharp bits, great design, very smooth holes. However, the case is staggering. When you pop the yellow clasp to open the case it is very poorly designed and when the case is open it slides completely off the case if you slide the clasp the other way. Inside, the mounts aren't very well designed, and large bits often fall out when the case is opened.
