    Damn fine bit!! Used it on the cover latch on my AKS74U build. Give it some fluid and watch it "drift" through metal like it was going through wood.

    You will be surprised at these drill bits, best I've seen yet and reasonable, I only buy from AOA because they are not robbing people with shipping charges like every one else, their parts kits are better and cheaper than any other gun site on line
