![]() ![]() The answer to the question of how many holes a bit can drill is not 100% answerable. ![]() Operator technique is another variable since how hard the operator pushes on the bit during the drilling operation can have a significant influence on the bit's life. The abrasiveness of the base material is another large factor red brick is more abrasive and will wear a bit faster than concrete. For example, a bit used to drill a 3” deep hole will drill 1/3 the number of holes made by a bit used to drill a 1” deep hole. The depth of the hole is a significant factor. The number of holes that can be drilled by a carbide tipped drill bit depends on many factors. The bit size required for each of the diameters are as follows: Drill Bit DiameterĮach diameter of the concrete screw has a specific diameter of carbide drill bit that must be used to ensure proper hole tolerance. The hole must be drilled using a carbide tipped drill bit that meets ANSI standards and a hammer drill. The hole size required for a Tapcon® is slightly smaller than the diameter of the screw being used. A hole for this screw must first be drilled into the base material before it can be inserted into the hole. ![]() Tapcons are American made as well as the original concrete screw. They have been manufactured since the late 1970’s by ITW/Redhead. Tapcon® concrete screws are designed to tap threads into base materials such as concrete, brick or block. Tapcon® concrete screws are a brand name for a concrete screw. ![]()
