Metallics DT832 High Speed Steel Drill-Tap Combo 8-32 (1pc)

It drills the hole and cuts the 8-32 thread in one pass, so you go from bare sheet metal or a strut channel to a threaded hole without swapping to a separate tap. The DT832 is made of high speed steel and ships as a single piece, so it suits electricians hanging box supports, straps, and fixture hardware where every screw hole gets threaded on site.

It cuts threads for a #8-32 machine screw, meaning a #8 diameter with 32 threads per inch, which is the common size for electrical box screws, fixture mounting hardware, and ground screws. If your job runs on 10-32 or 10-24 hardware instead, you need the matching drill-tap for that size rather than the DT832.

High speed steel is the standard cutting material for drill-taps used in mild steel, sheet metal, and strut channel, and that is what the DT832 is made from. It is not a masonry or concrete tool, so for anchoring into block or concrete you want a hammer-drill bit and an anchor rather than a tapped thread.

No. The drilling point and the thread-cutting section are on the same shank, so the DT832 replaces the drill bit plus tap plus handle sequence. All you need is a drill or impact driver that will chuck the shank, and cutting oil is worth using to extend bit life in steel.

One piece per pouch. The DT832 comes as a single bit in a pouch pack, so if you want spares in the van (drill-taps snap when they are run off-axis or at too high a speed) order the quantity you need up front.
