The life expectations can differ based on the compressive strength and aggregate mixture of the concrete. A SDS shank Tapcon drill bit can be expected to drill 100 holes minimum to full depth in 4,000 psi concrete. How many pilot holes can I expect to get out of a Tapcon drill bit? A straight shank Tapcon drill bit can be expected to drill 60 holes minimum to a 2" depth in 4,000 psi concrete. It is also recommended that the drill flutes be cleared 2 or 3 times when drilling. For optimal performance, it is highly recommended to drill through concrete with a rotary hammer or hammer drill in the hammer mode. Can I drill a pilot hole using a drill rotation-only movement? Although you can drill through concrete with a carbide-tipped bit using a rotary drill only, it will take longer and significantly reduce the drill bit life. Why do I need to clean the hole? Cleaning the hole prevents any dust that settles into the hole from potentially interfering with the Tapcon threads. What does ANSI stand for? The American National Standards Institute is a private, non-profit organization that oversees product standards, including masonry drill bits. These professional-quality, diamond, drill bits are designed for use in drilling asphalt and concrete. It also helps you stay safe while working. Making sure you have everything you need ahead of time helps you avoid delays mid-project. 3/16", 1/4" and 5/16" Tapcon anchors require specially engineered Tapcon drill bits, which are designed with tighter tolerances than standard ANSI drill bits for maximum holding power. 1 Gather Tools and Materials Before you begin drilling into concrete, gather all of the supplies and materials you’ll need in one place. Drive anchor using a hammer drill with nut driver or Phillips bit until. Using a blow out bulb or compressed air, remove dust from hole. Use the charts below to select the correct drill bit. Can I use standard ANSI drill bits to secure Tapcon drill bits? 3/8" and 1/2" Tapcon anchors can use standard ANSI drill bits. First you must understand the installation process of Tapcon Screws: Drill using a hammer drill, drill hole 1/4' deeper than anchor embedment. When it comes to length, there are standard lengths, but there also long masonry drill bits that range from 300 to 400. This will ensure that any dust that settles in the hole will not interfere with the Tapcon threads. Find out the types, sizes, and equivalents of different drill bit sizes with a quick reference chart and a full guide. How deep do I drill the pilot hole? The drilled hole for a 3/16", 1/4" and 5/16" anchors requires a 1/4" deeper hole, and the 3/8" and 1/2" anchors require a 1/2" deeper hole. Learn how to choose the right drill bit size for your projects, from everyday home repair and construction to hobby, metal working, and more.
