Due to the dust, you may also want to consider wearing a dust mask. Safety goggles are a must to protect eyes from dust and concrete chips.

Now that you have the appropriate hammer drill and bit, you should think about safety equipment. This could be compressed air, a wire brush or a shop vac/vacuum.

When drilling a hole to install a concrete fastener, it is also important to have tools on hand to remove residual dust from the hole. Below is a chart showing the different concrete anchors and their required hole diameters: Type of Fastener/Anchor Once you have determined the type of drill bit needed, you need to figure out what size hole is required for the fastener you are using. Both options are ideal for drilling holes for Tapcons. The adapter that is included in the installation kit is keyed into the chuck and the bit is then inserted into the adapter. This drill bit can also be used with a Tapcon® Installation Kit.

This bit can be put into a drill with a Jacob's style chuck. The Tapcon® drill bit that is typically included with a box of Tapcon® concrete screws has a round shank with a notch at the end. ** This drill bit is typically only used by professionals. The SDS max drill bit is similar to the SDS bit but has a larger diameter shank. The hammer bit is a straight hex shank that is held in place with a Jacob's style chuck.

The SDS drill bit is a Slotted Drive Shaft that is held in place by the slots on the sides of the shaft. The spline hammer bit has a spline shank that has 12 teeth that fit into the spline drive of a hammer drill. Carbide-tipped drill bits are simply named for their bit retention system (how the bit is held in the drill). The type of carbide-tipped bit needed is dependent upon the type of hammer drill being used. A proper bit for drilling a hole for a concrete anchor is an ANSI tolerance, carbide-tipped drill bit. For this reason, it is imperative to use a proper drill bit. When drilling a hole for a concrete fastener, the quality of the hole is critical. Carbide Tipped Drill Bits for Concrete Drilling These features are not necessary to get the job done correctly but will make a concrete drilling job easier. Some important options to consider when buying a hammer drill include: This dual action allows for quicker drilling with less effort, and more importantly, creates a hole of superior quality. The hammering action of a hammer drill will chisel away the concrete while the rotary action drills the hole. A standard drill is insufficient when drilling into concrete because the drilling/rotating action is not enough to break the concrete. It is important to use a hammer drill or rotary hammer drill in concrete applications. (This situation will be the focus of this article.)ĭrilling into concrete may seem intimidating, but with the proper tools and equipment, it is well within the means of the average Do-It-Yourselfer.

A hole needs to be drilled in order to install a concrete fastener or anchor. A hole needs to be drilled in a concrete, brick or block wall to create a pathway for pipe or wiring.Ģ. There are a couple of situations when a hole would need to be drilled in concrete.

The second chart below is a US fraction to metric mm for the more common sizes up to 4'.Drilling a hole in concrete is a common activity for professional contractors as well as Do-It-Yourselfers and is one that needs to be done correctly and safely. That is often found when trying to match a screw size using Digital Calipers (Inch Decimal to Screw Size) or drill a hole (Screw size to Nearest Fraction) for your project. It is very helpful to know the decimal equivalent for a US screw size you have.
