Comments on: Dewalt’s Impact Ready Drill Bits – a “Boring” Review

Hmm, that’s a good question. I suppose that the tapered web design could cause some compression of debris in cases where a bit is completely engaged within a workpiece. When dealing with materials shorter than the length of the cutting flutes, this isn’t really a concern.

When drilling deep holes into wood, no compression was observed, or at least if there was compression, it did not cause excessive heating, nor did any of the bits bind. In other words, if there was compression during testing, the effects are not noticeable.

For the drilling of many very deep holes, conventional bits will probably be more suitable.

I just have one question. Won’t the tapered web design, while increasing strength, also act as a compressor when clearing material?

Yes, during testing the bits were used with an 18V impact driver.

I like the unibody design. I’ve had enough 2-piece bits break on me.

Not sure if I missed it in the review, but was an actual impact driver used?

Excellent review! I haven’t heard about these bits before, but they look great and could be perfect for my needs. I’ll be sure to check them out during my next trip to Ace. thanks!
