Tapcon Drill Bits work best with Tapcon Concrete Anchors. They have a carbide tip that ensures the precise drilling of pilot holes. Tapcon drill bits are designed to work as part of a system. The system includes the Condrive Installation Tool, the Tapcon anchor, and the carbide-tipped Tapcon drill bit. For consistent performance, it is best to use the entire system.

  • Use with a hammer drill for best results
  • Carbide tip for strength and durability

What diameter holes does this bit create? Exactly 5/32" diameter? All holes I drilled were too big and tapcons didn't hold.

I don't know - I didn't measure the hole. I've put in dozens (maybe hundreds) of Tapcon screws of this size with these bits. If the screws aren't holding I would suggest it's not the bit. You need to overdrill OR clean out the hole. Tapcons fail if they hit too much debris when being set.

I don't know - I didn't measure the hole. I've put in dozens (maybe hundreds) of Tapcon screws of this size with these bits. If the screws aren't holding I would suggest it's not the bit. You need to overdrill OR clean out the hole. Tapcons fail if they hit too much debris when being set. It may also be technique - you need to keep the drill steady so you're not creating a bigger hole by letting the drill wobble around. Also, don't ream it out. I will sometimes remove the bit to let it cool, but do so carefully. Do not go in and out with the bit to oversize the hole diameter. Hope this helps.
Other possibility that's unlikely is that your bit is not straight.
Anchors are certainly more reliable than Tapcons. I have about 5% failure rate with small Tapcons. This is always due to debris in the hole more me over-tightening and snapping the head off. If it's critical to get every attachment perfect, anchors are likely better. When I can redrill as needed, it's hard to beat the convenience of Tapcons. If it matters, they make smaller holes (generally) and are very easy to remove. Read Less

Answer: 
It is supposed to ensure a tight fit but that only works in theory.
The problem is that concrete is rough and the drill bit doesn't cut smooth so you end up with more play than you should.
The Tapcon system doesn't really work that well -- I had the same experience. I didn't want to believe the Home Depot salesman who recommended the metal anchors instead but they work much better. Even the plastic are Read More

I'm not impressed with them. Read Less

Answer: 
For installing 3/16" Tapcon anchors, use a 5/32" Tapcon drill bit. For installing 1/4" Tapcon anchors, use a 3/16" Tapcon drill bit. If the holes are still too big, please call our Customer Service Department at 1-877-489-2726.

CUSTOMER REVIEWS

Rated 2.4 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Good bits for the price These bits are great. You need to have a decent drill to drive them. I tried them with a large but inexpensive hammer drill and all it did was dull the bits. Switched to my Milwaukee 12V hammer drill and these worked great. They need a little pressure in my experience and seem to cut better when they're hot. But don't cook them. I do 1/2 an inch, and let it cool off for a few seconds then another 1/2 inch. These bits slow down when they hit rebar in the concrete, but will go through with some patience. They are good for maybe 15 1.5" deep holes, or 22" in good, reinforced concrete. But for what they cost, you can't expect much more. They outperform similar Bosch bits I have purchased, which are 2x the price. May 2, 2016
Rated 1.0 out of 5.0 by lasted 4 holes This does not work on concrete block -- at least not with a regular drill (may have better luck with a hammer drill). After 4 holes the bit was useless -- polished smooth. I need a new bit -- and won't buy this brand again. January 31, 2016
Rated 4.0 out of 5.0 by Use only with a hammer drill I bought a 75-pak of 1-3/4 FH Tapcon screws, and the cheapest hammer drill on the shelf. I drilled holes for all 75 screws with the same bit. Tapcon's recommendation for a hammer drill is really a requirement. Without a hammer drill, the bit will just spin and burn up on the 1st hole. February 23, 2015
Rated 1.0 out of 5.0 by drilled one hole and bit was worn out this drill bit is one of the lowest quality I have ever used, out of the package it had a very noticeable run out and the carbide tips were so poorly welded into the tip that I had to clean the weld material away from leading edge of bit to start. August 1, 2014
Rated 1.0 out of 5.0 by Drilled one hole and then it did not work anymore Junk, Does not work as advertised. Tapcon screws and bits have not worked for me. Used in hammer drill as per directions, it drilled one hole and then would not drill anymore. Tapcon screw did fit in hole July 27, 2012
