Publishes the thickness it will tap: 10 gauge
TEMPO Greenlee DTAPKIT
A trade kit that publishes the one limit these bits actually have — the thickness of metal it will tap through, up to 10 gauge.
A combination drill-tap has exactly one hard limit and almost no listing publishes it: the thickness of metal it can get through. The tap section is short, so past a certain thickness the bit is still cutting thread when the drill flutes have run out of hole, and it binds and snaps. Greenlee states the figure — up to 10-gauge metal, about 3.4 mm (0.13 in) — and names the materials: aluminum, brass, copper, plastic and mild steel.
That is the specification that makes this a trade kit rather than a gadget. It is aimed at the work it is actually used for: tapping an enclosure, a strut, a panel or a box section where a through-bolt will not do, in one operation with a power drill. Deburring and countersinking are included as the third step, which matters because the burr a tap leaves is what stops a fitting seating flat.
The steel is hardened high speed steel, stated to outlast carbon steel tooling, and the kit comes with a quick-change adaptor and a case. The thread range is 6-32 to 1/4-20 with no metric sizes, so a workshop meeting both systems needs the thirteen-piece set on this shelf instead. One confusion to note: the brand field says TEMPO while the product and its catalog number, DTAPKIT, are Greenlee’s.
