Metallics CD8-BIT – Frequently Asked Questions
1) What size hole does the Metallics CD8-BIT masonry bit drill?
The CD8-BIT is a 3/16 inch diameter masonry drill bit with an overall length of 6-3/4 inches. The 3/16 inch diameter is the hole size for 3/16 inch masonry anchors, and the 6-3/4 inch length gives enough reach to drill through furring, a mounting bracket, or a box flange and still get full anchor embedment into the concrete or block behind it.
2) I am mounting conduit straps and panel boxes to a concrete wall. Is this the right bit for the anchors an electrician uses?
For 3/16 inch masonry anchors, yes. The CD8-BIT drills the 3/16 inch pilot those anchors need, and at 6-3/4 inches overall it reaches past strap bases, unistrut, and box flanges to put the full anchor length into the wall. It is a Metallics electrical fastener accessory, so it pairs with the 3/16 inch masonry screws and anchors used for strapping conduit and hanging gear on block and concrete.
3) Can I use a 3/16 x 6-3/4 masonry bit in concrete and block, or do I need a hammer drill?
The CD8-BIT is a masonry bit, so it is meant for concrete, block, and brick rather than wood or steel. Masonry bits of this type cut by percussion as much as rotation, so a hammer drill will clear the hole far faster and keep the carbide tip from glazing in hard aggregate. A standard rotary drill will work in soft block but will struggle in poured concrete.
4) Is the Metallics CD8-BIT sold as a single bit or a set, and is there more than one size?
One size only: the CD8-BIT is a single model, 3/16 x 6-3/4 inches. If you need a different anchor diameter you are ordering a different bit, not a different option on this one.
