Klein recently introduced a kit containing self-drilling taps that can be used to drill a hole, thread it, and deburr the edge—in a single operation. In the past this would have required two tools and separate operations.
With their 1/4-inch hex shanks the self-drilling taps can be snapped into quick connect adapters or chucked directly into drills and drill/drivers; Klein says they are not recommended for use in impact drivers.
Made from high speed steel, these tools are designed to tap up to 10-gauge metal (which is just over 1/8” thick) and can be used in aluminum, brass, copper, plastic, and mild steel. Applications include, but are not limited to: installing devices in electrical subpanels, rethreading or enlarging screw holes, and installing commercial hardware such as closers, panic bars, and kick plates on metal doors and jambs. These would be useful to anyone who works with thinner gauges of metal in the fields of construction, automotive repair, and industrial maintenance.
The kit comes in a plastic case and includes tools for six common hole sizes and thread patterns plus spares for the 6-32 and 8-32 sizes (Greenlee offers similar kits in metric and SAE but theirs don’t include spares). Replacements can be purchased individually for any drill/tap tools that break or go missing.
