Rotary masonry drill bits resemble hammer drill bits, but have slightly different tip shapes (at least from the few examples I’ve seen), and are typically shorter.
Most people are only familiar with hammer drill bits and SDS-style rotary hammer drill bits. Rotary masonry bits look the part of other masonry drill bits, but in my experience they are a lot slower to use. The only hex-shank masonry bits I’ve seen are these new impact-rated ones and Bosch’s impact-rated multi-construction bits. After doing some more searching online, it turns out that there are actually more brands and styles of rotary masonry drill bits than I was aware of. The Bosch and Black & Decker sets seem to have positive reviews on Amazon, so perhaps my experiences were with particularly bad quality bits.
Did you already know that such non-hammer and non-rotary hammer masonry drill bits existed? Having used all of the above, if you have to put a lot of holes in concrete or masonry borrow, rent or buy a rotary hammer and a proper SDS bit. Stuart, while my first experiences, about 30 years ago, using the rotary mason bits like the ones you pictured above, in a regular rotary drill were not impressive, adding a hammer drill proved a big step up. I do however have a couple of concrete drill bits so I must experiment drilling with these in non hammer mode (rotary). The Bosch Multi-Construction non hammer masonry bits are very popular over in the UK and Europe. I am not sure exactly how similar things are over in the US but we use a great deal of red and brown plugs for fixing into brick and concrete. I still use an SDS plenty and a combi drill with standard masonry bits but if I only need to do say a dozen holes I will often just grab the drill driver and a Multi-Construction bit.
They drill tile, metal, timber and I once in desperation managed to drill a mirror with them too! Co-workers were always amazed when I drilled a hole in 50 year old concrete pillars with my Bosch PS-20 and normal hammer drill bits. I like having the options, so you can spend a few bucks and use the right drill bit for the drill you already have to get the job done, rather than having to buy or rent a new tool to do the job, but the downside is the confusion over what should be used with what, at least for the average consumer.
They are also good for drilling pilot holes for screws into things like RailRoad ties, which often have dirt or gravel embedded in them, which dulls and can even ruin a regular bit.
Bosch spline rotary hammer bits are carbide-tipped and fit Bosch as well as other spline-drive hammers. Self-contained test units which provide a rapid, easy to use, specific test for lead on any surface.
Includes phillips, slotted, torx, clutch, spline, square, spanner, hex, triwing, pozi, metric bits and holders. Bosch carbide-tipped SDS-Max rotary hammer masonry drill bits feature tips that stay sharper longer and deliver more holes within their ANSI specification than competitors' bits. Focus rotary bits are available as milled steel-teeth bits or as tungsten carbide insert (TCI) Tricone bits. TCI Tricone bits offer a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock.


Drilling for water is a demanding operation where rock conditions can vary from work site to work site.
With Focus rotary bits there are a magnitude of cone designs with both open and sealed bearings to match these conditions. Focus rotary drill bits come in 320 different models, from small milled steel-teeth bits to multiple row, carbide insert TCI Tricone bits.

High Speed Steel Bits – Harder than steel blades and will stay shaper slightly longer.
Titanium Coated Bits – Cost more than High Speed Steel, but this is a tougher material and will stay sharper longer. Carbide Tipped – More expensive than the previous bits but will stay shaper longer than any of them. A hole saw is great to make large holes, but make sure the drill can handle the extra force or your burn the motor out very quickly. The most common to find and is used for general drilling into wood, light metal and plastic. The bit can be changed and is great for making the top of the hole a little wider so when you put the screw in, it is flush with the top of the board.

In the post, I mentioned how the new Bosch drill and screwdriver bit assortments come with rotary masonry drill bits, and how this was an indication that the accessories might not be not up to full Bosch Tool quality levels. Maybe 7 or 8 years ago, I searched for them high and low, before finally giving up and purchasing a hammer drill.
They look like hammer drill bits, but they can only be used in drills with a rotary-only action.
It looks to me like the Bosch and Skil sets are identical, except maybe in how they’re packaged. I’m going to look more closely at a couple sets of drill bits I have to look at the differences. Here all our houses are built with bricks and mortar so every curtain rail, picture hook, light fitting etc has to have a hole drilled.


They drill pretty clean holes without crumbling the surrounding mortar, which is pretty good for the price if you’re just wanting to drill some anchor holes and not spend $$$ on a hammer drill to do it. Hopefully the packages are well marked as to what drills the bits are for – and what drills they should not be used with. Also, Bosch shafts wear at a much slower rate than most others and can take more abuse because of Bosch's technologically advanced conditioning process. Milled steel-teeth bits can be hardened and surfaces treated with carbide for extra resilience. The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. The environment is tough; and inserts, bearings, and shirttails are often subject to three shifts a day in hard abrasive rock. They are equipped with large roller bearings that can take maximum load, specially designed flushing holes for effective cooling and cuttings removal, specially designed cone heads and inserts for maximum penetration, and three shirttail designs to facilitate the best protection for the drill bits.

Brazed tungsten carbide tips have 120° chamfer and are specially tempered for strength and long life.
I bought the above-shown Black & Decker Firestorm bits after buying my hammer drill, just in case. Correction: Dewalt makes a 3pc set of hex-shank rotary masonry drill bits ($15 via Amazon). After that, start budgeting for a corded hammer drill that’ll give you years of service. Before I bought my first hammer drill I actually tried repeatedly retracting the bit from the hole a few inches and slamming it back in to create my own hammer action.
I was only drilling a hole big enough for plastic anchors, but it went fast enough and the job always got done. There are also open and sealed bearings available as well as three types of shirttail protection to choose from. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. My pre-hammer drill experiences were with a couple of individual rotary masonry bits I received in packs of masonry wall anchors.
