I’ve been which means to write about Irwin’s effect-rated masonry drill bits for some time now. They’re at present available at Amazon and presumably elsewhere – I haven’t checked – and look like a fantastic thought.
Believe about it: hammer drills are fantastic if you want to drill just a few holes in masonry supplies. But for much more than that, they type of suck. For lots of holes or bigger holes, you want a rotary hammer, which as you probably know is a fully various kind of beast.
Influence drivers can provide a lot of torque, and they also have reactionless torque transmission. If you’re using an impact driver and a bit binds or jams, the tool won’t twist your wrists, or at least it shouldn’t. If the identical occurs in a drill or hammer drill, the tool will counter-rotate.
Or at least that’s what takes place with most drills. Bosch tends to make some heavy-duty drills with wrist-saving anti-kickback security sensors.
I recently noticed that Dewalt has just come out with influence-rated masonry drill bits of their own. I kept putting off a post about just the Irwin bits, but seeing Dewalt come out with their personal drill bits of this style was enough to finally push my pen to paper.
Effect drivers usually provide larger speeds, reactionless torque, and greater max torque limits compared to drills.
If these bits take off, hammer drills may ultimately drop their appeal. But I don’t consider will take place.
Rotary-only masonry bits are lousy, at least the couple of ones I’ve utilized. Hammer drills provide a vibratory-type of impact motion which, even though nowhere near as efficient as the piston-style hammering of a rotary hammer, need to perform far better than rotary-only action. If you use these bits in an influence driver, which do not provide any chipping-away-at-masonry-materials vibratory or influence motions, wouldn’t they perform worse than maybe the same bit in a hammer drill?
Effect drivers are not hammer drills. Sometimes hammer drills are called impact drills, but they are still inherently diverse than influence drivers.
It’s like the difference amongst stirring a pot of sauce and mashing potatoes. One particular supplies rotary influence pulses, and the other pulses in a perpendicular path.
Portion of me is psyched about these new impact-compatible masonry drill bits, but a larger element of me wonders regardless of whether they’re any good. My feelings would be less mixed if these had been impact-rated multi-material masonry bits.
Possibly I shouldn’t be so hasty to judge. Dewalt says their new Impact Prepared masonry drill bits have an innovative flute style top to faster material removal for simpler drilling. They’re also sized for frequent Tapcon anchor installation.
Do you genuinely require a rotary hammer or even a hammer drill for 1/4″, three/16″, and 5/32″ hole sizes?
You can acquire a 3pc set of the Dewalt bits for ~$ 14, and person sizes are at the moment priced at ~$ ten each and every. The Irwin bits, which are currently shipping, are priced at ~$ 29 for a six-piece set, and ~four-six each and every. There’s also a smaller sized 5-piece set for ~$ 18.

I possibly wouldn’t hesitate to acquire a pack of impact-rated masonry drill bits the next time I have to install a couple of smaller sized masonry anchor sizes. They sound convincing enough, but I nevertheless have my hesitations.
Even though an influence driver lacks the vibratory action of hammer drills, which helps to break up masonry components, this must also mean reduced vibration, and this a much better user experience. So even if they don’t execute very as properly, they might be easier on your hands and arms.
Unrelated, but whilst we’re speaking about masonry drill bits…
A while back an individual asked for my opinion about masonry drill bits for hammer drills. Sorry, I have your e mail starred and flagged as unread, but haven’t finished the full Reader Question post about it however. If you’re reading this, I’m going to have to say Bosch all the way – anything like their 7pc set which is $ 24 by way of Amazon. I bought that set, or one quite much like it, and added in one or two other sizes. Hold in mind that this and other sets often have duplicate bits of much more delicate bit sizes.
In terms of impact-compatible masonry drill bits. Dewalt has worked hard to refresh their Effect Prepared, FlexTorq, and MaxFit (what’s the distinction?) impact-compatible lineups in recent years. Irwin also launched a new impact-compatible bit lineup in recent years. And whilst we’re on the subject, Milwaukee’s new Shockwave drill and driving bits are also coming out soon. But there hasn’t been a lot buzz from Bosch.
So even though I tend to favor Bosch masonry drill bits, and of course SDS masonry drill bits as nicely, I don’t feel that would quit me from wanting to try the Dewalt bits talked about above, or possibly even the Irwin ones.
