I use a lot of masonry drill bits but have never tried Diablo brand. But considering price, sizes and the fact these have a hex shank, I decided to give them a try. I’m not disappointed in the least.Many brands are making drill bits with the hex shaft which allows them to be used in either a standard drill chuck or fit your cordless impact drivers.I tried these bits in both my corded and non corded Milwaukee hammer drills as well as my Ryobi impact driver. In every tool, these bits bored through a 4 inch cement block in seconds and came out clean and ready for more. If you use mason bits even occasionally, you’ll want to give these a try.

I own many Diablo products and I know they are built well and designed to last as well as get the job done fast, The bits come in a nice plastic case. To open the case just cut around the ridge with a utility blade then pull the case halves apart. You can see that in my pictures. The 5 bit set covers most standard sizes for anchors in concrete, stone and brick. You can feel the rugged cutting edges on the bits ready to chew through stone material.They have a standard 1/4 inch hex locking shaft to fit most hammer drills and impact driver/drills.You get a 5/32, 3/16, 1/4, 5/16 and a 3/8 inch bit all of them 6 inches long at an unbeatable price.

This is a review of Diablo’s 5-piece “Red Granite” “Speedemon” carbide-tipped hammer bit set; Item #DMARG1220-S5. All bits are 6″ long.Made in China.First, once you realize the package is a “cigarello-type” case and not a clamshell, it’s easy to open. It’s made from a soft [non-brittle] PVC, is flat and very compact; travels easily in the back pocket.Second. All the right ‘step-downed’ sizes for Tapcon screws.Third. 1/4 hex drive can be used in standard chuck.Fourth. Carbide is brazed, not soldered. Cleaner holes, longer life.Fifth. The “Grip Point” feature works … tip wanders less when starting hole.Sixth. Flites clear material well.Summary. These should last a couple dozen holes apiece it you [a] back off the pressure and let the bit do the work; [b] use them only in ‘hammer mode’; [c] don’t over-spin … I think 700, 1,200 rpm is sweet spot.

Handy set of drill bits to have for masonry at a great price. Carbide tip which is fairly standard and long lasting if you keep the drill speed down. They work through brick and cinder block easily but slow through concrete (particularly when they hit aggregate rock). The diameter of the bits are 5/32″, 3/16″, 1/4″, 5/16″ and 3/8″. These bits are 5-7/8″ in total length but you can only drill to a depth of about 4-3/8″. The bits have a hex end and will fit in a standard chuck or in a hex driver, so they are great for my drill/hammer drill with a keyless chuck. I like them better than standard round masonry bits as there is no slippage of the bit. This product is made in China.

This set of DIABLO SPEEDemon Red Granite Carbide Tipped Hammer Drill Bits lived up to the manufacturer claims. I performed a comparison test with the DIABLO bits against brand B bits. Five holes per bit all using a brand M hammer drill with the M12 battery system. Both 3/16 inch bits were new out of the package. The average drill through time on the 2.25” thick concrete paver for brand B was 22.474 seconds compared to the DIABLO bit which had an average of 18.616 seconds. Comparing the holes drilled, the DIABLO bits absolutely left a cleaner and more uniform hole in the paver. I also noticed the DIABLO bits pulled the debris out of the hole while drilling much better than brand B. The DIABLO bits feature a hex shaft that will be gripped by a drill chuck much better preventing spinout. They can also be used in an impact driver but from a speed perspective a hammer drill is far superior. The case for the bits is a sleeve design with indents to ensure it does not slide open on its own. Bits included are the following sizes: 5/32, 3/16, 1/4, 5/16 and 3/8.

This hammer drill Red Granite Carbide Tipped Bit Set did a good job of drilling into 10 year cured concrete and allowed me to install Red Head bolts into the concrete to hold down a large drill press. They drilled like they should and did not appear to dull at all. I kept the speed fairly slow, the instructions say not to go over 2000 rpm. I used it at about 400 rpm and it worked great.

Masonry bits are kind of tough to do a good comparison. The problem is the material you are drilling in can vary greatly in hardness. Over the years, I’ve had several that are definitely high end brand units, and had results that I considered somewhat marginal. Of course, I bought them for some tough drilling. I see on Diablo’s website they have recently introduced some larger super masonry drill bits with 4 carbide inserts and is supposed to be more aggressive cutting and tolerate to high temperatures. In comparing these to some other masonry bits I have, the rake angle of the carbide cutter is more aggressive, which is good for faster cutting. I was a little surprised they used a hex shank on these bits, sized for screwdriver bit holders. I certainly wouldn’t recommend using your screwdriver bit holder. However, drill chucks have three jaws which will grip the hex shank nicely, for a no slip grip. I’d consider this a feature. The shanks are long enough to bottom out inside the chuck. The size is stamped on the hex.I haven’t used the smaller diameter bits yet, but care must be taken not to buckle them when drilling, as they are long and slender.These bits appear to be as good as any I’ve had, and better than most.I thought I’d give some comments on masonry drilling. 1. A hammer drill really makes a big difference in drilling concrete. 2. If you have the option, drilling in concrete that is not fully cured makes drilling much easier. 3. Try to keep the bit cool. I pour some water into the hole, plus have a container of water handy to dip the bit in when it appears to be getting hot. 4. When boring larger diameter holes, I always start with a ¼” hole, and the step up to the larger sizes. 5. Although I consider masonry bits to be disposable, I’ve had some success in re-sharpening carbide tipped bits on a bench grinder. Be sure the heal of the carbide tip is lower than the cutting edge. I’ve only been able to sharpen them one or two times, but these have larger carbide, so they may allow multiple sharpening.In the past, I’ve only used lead anchors inside masonry holes, but recently I’ve had good success using plastic anchors.

These bits were definitely put to the test as we drilled non stop through concrete using a Hilti hammer drill. I’d buy more of these. Two thumbs up.

DIABLO SPEEDemon Red Granite Carbide Tipped Hammer Drill Bit Set (5-Pieces) – I have used Diablo saw blades for several years and very happy with their performance; I wanted to try their masonry drill bits. My expectations were met. I can drill nice round holes in seconds using a hammer drill and even in drill mode they worked great just a little slower.I used them to replace 5 basement windows set in 65 yr. old concrete. Each window required 4 holes drilled and secured with tapcon screws. Drilling was almost effortless and best of all I didn’t break any bits and the carbide tips are still in great condition.The bits come with hex shanks that fit in any drill or impact driver.

Great bit set. 5/32 to 3/8. Watch the video and you’ll see how well and how quick it works. I like the red color. Makes it easier to find them when I set them down and forgot where I put them. They have an aggressive tip that’s built for action. I’m impressed with how easily it goes through time hardened concrete. My Tapcon falls short to drill as cleanly or quickly as these Diablos do. I like that the bit bases are 1/4″ Hex. I can simply pop them into my 1/4″ QR hex impact for easier materials. If it’s a bear of material, I’ll go to my hammer drill. 6″ is a great bit length. Overall, these bits have earned a rare 5 star review from me. Great bits. Try them, you’ll like them

The concrete drill bits worked well, they stayed fairly sharp throughout the process of drilling sixteen 3/8 holes.

An absolutely superb set of masonry bits by diablo. We all know that diablo makes great reciprocating saw blades and circular saw blades and these bits are right in line with the quality of those blades.I paired the bits with a Milwaukee m18 fuel hammer drill and the bits easily powered through a concrete slab, brick and a paver stone. The bit went right through with no issue and very quickly and did it multiple times just like it was the first time.The bit set 5 bits ranging in size from 5/32” to 3/8”. Great set that gives you plenty of range for tapping of any other need you might have.I would definitely recommend this set
