Metallics 112CTB – Frequently Asked Questions
1) What thread does the Metallics 112CTB tap cut?
The 112CTB is a 1-12 tap, so it cuts a 1 inch diameter thread at 12 threads per inch. That is the common UNF/rod size used for 1 inch all-thread and larger hanger rod work, so match the rod or fastener you are threading to 1-12 before you cut.
2) What is the difference between a bottoming tap and a taper tap, and which do I need?
A bottoming tap like the Metallics 112CTB has almost no lead chamfer, so it cuts threads nearly to the bottom of a blind hole. It is not the tap you start a hole with. Standard practice is to start the hole with a taper (plug) tap, then follow with the bottoming tap to finish the last few threads at the base. If your hole goes all the way through, you do not need a bottoming tap at all.
3) Is the Metallics 112CTB carbon steel or high speed steel?
Carbon steel. That suits hand tapping and chasing or cleaning up existing threads in mild steel, aluminum, and softer materials. For production tapping or harder alloys, a high speed steel tap holds its edge longer.
4) Can I use the 112CTB to clean up damaged 1 inch threaded rod?
Yes, chasing damaged or paint-fouled 1-12 internal threads is a common use for a carbon steel hand tap. Note it is a 1-12 tap, so it cuts female threads in a hole or nut, not on the outside of a rod. Re-threading the rod itself takes a 1-12 die, not a tap.
5) How many taps come in a Metallics 112CTB pack?
One tap per pack, supplied in a pouch. If you are stocking a truck or a shop for repeat 1-12 work, order by the piece accordingly.
6) What part number do I order for a 1-12 bottoming tap from Metallics?
Metallics part number 112CTB. The designation reads straight off the thread: 112 for 1-12, CTB for carbon steel tap, bottoming.
