![]() This assures it won’t obstruct the installation. Drilling dust settles in the hole’s bottom. Tapcons must be inserted 1/4-1/2” deeper than the concrete screw. Tapcon should be used at length equal to or greater than the formulae’s numbers. The maximum screw length is derived by adding the material thickness to the maximum embedment of 1-3/4”. The minimum length of concrete screw for any application is calculated by adding 1” to the material being secured. Tapcon concrete screws require 1” of base material embedment. Tapcons must be inserted 1/4 to 1/2” deeper than the concrete screw. If in doubt, prepare extra bits before drilling holes for concrete screws. The question of how many holes a bit can drill cannot really be answered. The operator’s technique also has a role in the bit’s life. Red brick is more abrasive than concrete and will wear faster. For example, a 3” deep hole will produce 1/3 the holes as a 1” deep hole. The number of holes a carbide-tipped drill bit can drill depends on numerous factors. What Size Drill Bit Do I Use For 5/16 Tapcon? When used with Tapcon anchors, the driving and holding power is increased.On the job, there is less breakage when using hammer drills.To attain optimal holding power, long, precise holes are required.A precise fit ensures anchors install quick and last for a long time.Diameter of Tapcon Concrete ScrewĬarbide-tipped Tapcon Drill Bits are manufactured with tighter tolerances than ANSI standards, allowing you to: The following are the bit sizes required for each diameter to achieve maximum holding power. To maintain adequate hole tolerance, a specified diameter of the carbide drill bit must be utilized for each diameter of the concrete screw. The carbide tip cuts through concrete and masonry with ease. SDS drill bit: The SDS drill bit is designed for maximum use in rotary hammer drills, offering effective, high-torque drilling with no slippage.Ordinary drill bit: The standard drill bit is designed to drill smaller pilot holes in concrete, block, and brick and is compatible with Tapcon anchors.A hammer drill and a carbide-tipped drill bit that fulfills ANSI requirements must be used to drill the hole. Size of the HolesĪ Tapcon requires a slightly smaller hole than the diameter of the screw being utilized. It’s no good looking for drill bits until you know the things that determine what you need. (Read Deck Screw Sizes Chart) What Size Bit Do You Need For Tapcons? In our guide, you can use our Tapcon screw size chart to get the right Tapcon drill bit size.īy the end, you’ll be able to find the right drills and drill bits to get the strongest holding threads that offer an accurate fit, thus obtaining higher tolerances of your concrete anchors. ![]() When using the right drill bits, you get precise holes to get maximum holding power for the job, increased drive, and less breakage. To use these screws, you need to drill a hole for the screw from there, you insert the screw where it then taps the hole and anchors itself to the concrete. The ITW/Redhead Corporation has been manufacturing these since the late 1970s, and like the original concrete screw, they are manufactured in the United States. Tapcon concrete screws are designed to tap threads into various base materials, including concrete, brick, block, and other masonry. ![]() ![]() Tapcon Concrete screws are a type of concrete screw sold under the Tapcon brand name.
