Klein has come out with new combination drill and tap bits that can create threaded holes with a power drill, driver, or screwdriver, in just a single step.
These new bits will be available in 6 sizes – #6-32, #8-32, #10-24, #10-32, #12-24, 1/4-20, and the set will include extra #6 and #8 taps. The drill taps can be used in aluminum, brass, copper, plastic, and mild steel, up to 10 gauge thick (which is 0.1345 for mild steel).
The drill taps are engineered with 1/4″ hex shanks, for use with quick-connect chucks, and are made from high speed steel for performance and durability.
Klein is bundling the drill taps as part of an 8pc (6 sizes) set (catalog #32217), and replacement taps are also available.
The new drill tap bits also have a deburring component that can slightly chamfer holes for cleaner results and easier fastener insertion.
These aren’t the first tools of their kind – you can find similar combination drill taps from Greenlee, Champion, and other brands. Still, it’s nice to high quality bits under Klein branding.
The street pricing is a bit steep – $57 for 8 bits seems like a lot, although I don’t think I could put together a kit with 6 drill bits and 6 spiral taps for less. Industrial-grade combination drill tap bits are priced at $15 to $18 each, for the sizes included in this kit, making Klein’s pricing look more reasonable.
However, for the price, I would expect these bits to be made in the USA. They’re not, they’re made in China. It will be interesting to see how these bits compare to other brands’ combo drilling and tapping bits. Maybe the higher pricing of these Klein bits reflects better quality or performance.
I’m eager to try these out, although they’re not going to be suitable for all applications. Curiously, Klein mentions a 10 gauge drilling and tapping capacity, but some of their product photos and the promo video show the bits being used on thicker bar stock.
