Before a Tapcon masonry screw can be installed, a hole must be drilled into the masonry. Use a hammer drill to ensure that the hole has the proper tolerance. The carbide bit diameter required for the 3/16” screw is 5/32”.
The Tapcon drill bit must be used in a hammer drill, and the hammer drill must be set in the hammer and rotation mode. Hole tolerance is critical when installing Tapcon concrete screws. To produce the quality hole required, the Tapcon bit must be used in a rotary hammer drill.
If you're wondering how to drill into brick without a hammer drill, it's not as simple or straightforward, but it is still doable. Drilling into a brick wall with a regular drill requires a high-quality masonry bit at the least. With no hammer action, the tool has to rely on its turning speed.
Concrete screws provide a quick, easy and incredibly strong way to fasten to concrete. And best of all, there's no hammering required or anchor or shield to install. All you do is drill a hole and drive in the screw.
Try getting as much dust out as possible or drill the hole deeper so the dust is below the depth of the length of the tapcon. Drilling deeper for tapcons is not a problem, drilling not deep enough will make the tapcon spin out therefore negating the fastening ability.
For example, a 2x4 is 1-1/2” thick, so the minimum length of tap con to use would be 1-1/2” + 1” = 2-1/2”. The maximum embedment for all tap con screws is 1-3/4”.
While there are a lot of ways to fasten to concrete Tapcons are a great light-duty way to do so. They are accessible to most homeowners and DIY'ers because they are easy to use and only require having, a drill with a hammer setting, an impact driver and a masonry drill bit.
Hammer drills don't just bore holes into masonry, though. Most allow you to turn the hammer function off, so with standard drill bits you can use them for the same tasks as cordless drill/drivers. However, care has to be taken. They still deliver a lot of power and can easily break small-diameter drill bits.
If you only need a hammer drill occasionally, perhaps you could get by with this Mastercraft hammer drill adapter. After chucking the adapter into your drill, you activate the hammering action by holding onto the adapter while you operate the drill. The adapter requires a drill with at least a 3/8″ chuck.
masonry bitsDrill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest, when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.
Definition of star drill : a drill for stone or masonry that has a star-shaped point and that operates by being struck with a hammer and rotated.
Masonry screws are removable and reusable The removal and reinstalling process may cause the tapped threads in the base material to deteriorate, which affects the holding values of the masonry screw. Removing the masonry screw can be accomplished by simply turning the head of the screw counterclockwise.
Though you don't need to water down the concrete, the water will help to collect and remove the drilling dust, which can be hazardous to your health and "clog" the drill bit. The water can also help to keep your bit from overheating, which in turn helps keep the bit from shattering.
*A safety factor of 4:1 or 25% of ultimate pullout/shear value is generally accepted as a safe working load. 340 lbs.
Stainless Steel Tapcons are reliable, strong, and have outstanding corrosion resistance. These screws are ideal for using to attach fixtures and lumbers to all types of masonry bases, including concrete, brick, and block.
The depth of the hole for a Tapcon® should be a minimum of 1/2" deeper into the base material than the screw will penetrate. If the Tapcon® screw bottoms out in the hole before it is fully inserted and too much torque is applied, the Tapcon® may break or shear off.
It is possible to drill into concrete with an ordinary rotary drill. Rotary drills take longer to drill into concrete than hammer drills and more physical effort is required. Excessive heat build-up can break the drill bit. One way to speed up the process and to avoid breaking the drill bit is to keep the bit cool.
You can remove the chuck from a standard corded electric drill and replace it with an SDS chuck.
There are also different materials used to make the types of drill bits used for concrete, brick or tile. Almost all drill bits are made of metal. With few exceptions, metal bits are the most practical choice for every surface including wood, concrete, tile, glass and metal surfaces, as well.
A brace is a hand tool used with a bit (drill bit or auger) to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip.
around 3/16 inchThe smallest masonry bits are around 3/16 inch in diameter, with larger bits topping out at the ½-inch size. Hole saw bits have sizes that go up to 4 inches or more.
The depth of the hole for a Tapcon® should be a minimum of 1/2" deeper into the base material than the screw will penetrate. If the Tapcon® screw bottoms out in the hole before it is fully inserted and too much torque is applied, the Tapcon® may break or shear off.
Tapcon® Concrete Screws: Tapcons are removable because they are threaded screws that tap threads into the concrete, brick or block. By simply turning the screw counter-clockwise, these concrete screws will thread its way out of the base material.
Lubrication can extend the life of the drill bit quite a bit if the lubrication is done whenever drilling holes. While drilling into glass or tiles the drill bit tip should never be hot and it should be almost warm. This lubrication can help drain away the burr from the drilling process.
Drilling into concrete can be accomplished with a 12 volt drill. Drilling a hole into concrete is best accomplished with a drill that you plug into a wall outlet. Drilling into concrete with a 12 volt drill is similar to using a corded drill for the task and requires the same basic drilling technique.

Self-tapping screws are concrete screws that tap threads into the base material such as concrete, brick or block. The original self-tapping and the most widely recognized one is called Tapcon, which is derived from Tapping Concrete.
In most cases, yes. While a cordless drill will not be as effective in drilling through concrete, it can get the job done. Your drill's battery power and other drilling features will play a role in its ability to drill into the concrete effectively.
The most common reason a drill won't penetrate a wall at all is because the drill is spinning in the wrong direction. If the drill bit enters the wall and then hits resistance, the typical cause is a metal plate or masonry obstruction.
If you only need a hammer drill occasionally, perhaps you could get by with this Mastercraft hammer drill adapter. After chucking the adapter into your drill, you activate the hammering action by holding onto the adapter while you operate the drill. The adapter requires a drill with at least a 3/8″ chuck.
SDS Rotary Hammers are similar to Hammer Drills in that they also pound the drill bit in and out while it's spinning. They use a piston mechanism instead of a special clutch enabling them to deliver a much more powerful hammer blow than traditional Hammer Drills - they are able to drill larger holes much faster.
hammer drillThe best drill for concrete today is one of two tools: A hammer drill or a rotary hammer. They both do essentially the same thing but are vastly different tools.

The most common type of drill bit that you use when drilling into concrete is masonry drill bits. This is true whether you are using a regular drill or a hammer drill. It would be best if you used a masonry drill bit made of tungsten carbide. That way, it is strong enough for concrete drilling.
