First I bought the HD version from Dewalt. They wobbled when drilled like they were off center and the little one broke off in the wood after only 2 days of limited use. Reviews have shown that this is a common problem with Dewalt and other brands sold in large stores. I bet they're all just repackaged under different brands. Further research led me to Snappy. Immediately after using the Snappy Bits, I was pleased that they felt focused and secure. As with other brands, the #s don't seem to fit on the same screw # so I used the smallest for your medium 1-4 inch screws.
