Review on 🔧 Delve into Efficiency and Durability with Disston E0212171 Bi Metal Industrial 20 Piece Set by Bryan Hill

The body is weak, the partitions are thin and bend easily. In the 4th hole I drilled, the drill bit broke. The large mandrel has a short drill. So if you use a 4" hole saw with a larger mandrel and you have 1/8" b4, the hole will start cutting without giving you enough centering. But durable and cuts we) but for thicker wood you need a strong drill because of the high voltage I burned a cheap drill.
