Metallics DT3816 – Frequently Asked Questions
1) What thread size does the Metallics DT3816 drill-tap cut?
The DT3816 drill-tap combo cuts a 3/8-16 UNC thread, meaning 3/8 inch diameter at 16 threads per inch. It drills the hole and taps the thread in one pass, so you set rod hangers, strut, or beam clamps in sheet steel or strut channel without switching to a separate tap.
2) Will a 3/8-16 drill-tap accept standard threaded rod for hanging conduit and pipe?
Yes. 3/8-16 is the standard coarse thread used on 3/8 inch threaded rod, hanger rod, and most beam clamps and strut nuts, so a hole tapped with the DT3816 takes 3/8 inch rod or a 3/8-16 bolt directly.
3) Is the Metallics DT3816 high speed steel or carbide?
High speed steel. HSS handles mild steel, strut channel, and sheet metal well and can be resharpened at the drill point; it is not intended for hardened or stainless structural steel, where you would want a carbide or cobalt tool instead.
4) Do I still need a separate drill bit and tap if I use the DT3816?
No. The DT3816 is a combination tool, drill point and tap on one shank, so a single tool makes the pilot hole and cuts the 3/8-16 thread. You do need a drill or driver that can run it at low speed with steady pressure, plus cutting oil for clean threads on steel.
5) How many drill-taps come in a Metallics DT3816 pack?
One piece, supplied in a pouch. If you are tapping a run of hangers across a building, order multiples, since a single bit is a consumable on steel.
