It’s hard enough to tell how deep you’re drilling with rotary hammers when you’re drilling downward or sideways, but drilling overhead makes it even more difficult. Try “feeling” your way to a perfect depth while your arms burn like mad. DeWalt claims to feel your pain, which is why they just launched a depth control system — you know, to remove the guesswork. The cap you see in the picture above mounts to the bit and serves as a stop to keep you from over-drilling. You can adjust its size by twisting it then locking it in place. Seems pretty simple.
A couple of caveats: First, if I’m reading the press release correctly, it’s designed for use only with DeWalt’s own proprietary SDS Plus bits — kind of a downer if you’re already stocked up. Then again, I’m betting that anyone who drills enough to benefit significantly from saving a few seconds drilling each hole — DeWalt envisions these as a time-saver for folks who do a lot of repetitive fixed-depth drilling, like installing drop-in anchors or other plumbing/electrical fixture mounts — probably chew through enough bits to offset that issue. And a quick check shows little difference in pricing between DeWalt’s bits and competitors’.
We didn’t see it in stock yet (hey, they just announced the thing today), but expect to pay around $30 for one when they come available.
