Metallics CD7-BIT – Frequently Asked Questions

1) What size hole does the Metallics CD7-BIT masonry bit drill?
The CD7-BIT is a 3/16 inch diameter masonry drill bit with an overall length of 5-1/2 inches, so it cuts a 3/16 inch hole in concrete, block, or brick.
2) Is a 3/16 inch masonry bit the right size for 3/16 concrete screws?
Yes. Concrete screws are installed in a hole matched to the nominal screw diameter, so 3/16 inch concrete screws take a 3/16 inch carbide masonry bit, which is what the Metallics CD7-BIT is. The screw threads cut into the undersized walls of that hole to hold.
3) Can I use this bit in a hammer drill, or does it need a rotary hammer?
The CD7-BIT is a straight shank masonry bit, so it chucks into a standard corded or cordless drill and into a hammer drill in hammer mode, which is how 3/16 inch holes for concrete screws are normally drilled. It is not an SDS bit, so it will not fit an SDS-Plus rotary hammer without a chuck adapter.
4) Will the Metallics CD7-BIT drill through steel or wood as well as concrete?
No. This is a masonry bit, ground for concrete, block, brick, and mortar. Use a twist drill for steel and a brad point or auger for wood. Running a masonry bit in steel dulls the carbide tip quickly and gives you a ragged hole.
5) How many models of the Metallics CD7-BIT are there?
One. The CD7-BIT is a single part number in one size, 3/16 x 5-1/2 inches, so there is no size or finish option to specify when you order. If you need another diameter for a different screw size, that is a different Metallics bit part number.
