A: Hello - Thanks for reaching out! You can use a 5/16" Tapcon+ Concrete Anchor.
A: Sounds like you are not using a hammer drill. A hammer drill will make it last much longer, otherwise the heat will dull it faster
A: Yes. I used a DeWalt drill and drilled into cinder block. No problems.
A: Yes. Have used them for years with my standard DeWalt drill/driver
A: Yes, most of the drill bit works with standard drill.
A: No, you can not because this drill bit is for concrete only used in a hammer drill !!
A: Yes you can drill into a 2x4 with this bit, but your best choice would be a standard wood bit as this is a masonry bit for concrete, brick, etc. The wood bit will also give you cleaner drilled hole.
A: Great for securing wood to concrete.
A: The best out there!!
