Is the “Earthquake Prep” expansion anchor outdated? The smart and ultimate concrete anchoring technique using “TAPSTAR”

I’ve always had some doubts about the structure of existing concrete anchors.
The process of “drilling, hammering, and expanding” creates the thread pattern.

Even with the hammering and expanding action, as long as it doesn’t “slip” in the location, there shouldn’t be a problem.
However, when installed in poor-quality concrete or block-like materials, they can crack.
If it fails, it’s impossible to remove. . . .
I used to hate it, thinking what unreliable, crappy material this is. . .

But this time, with earthquake preparedness, I absolutely had to anchor into concrete.
I researched and researched, and finally found it.
It finishes with surprising ease and “can even be removed.”
*You can unscrew it by turning it in the loosening direction.
If you want to anchor into concrete, give this a try.

Attention! The TAPSTAR insertion tool is included.

You might be tempted to buy it separately, but “it’s included,”
so just buy the anchor in the length you need.

You drive it into the ground with this specialized bit.

It has a somewhat unique head shape.
Just screw it in with an impact driver and you get a perfect finish 100% of the time.

Removal is also easy.

Installation is simple, but don’t cut corners

① Drill the pilot hole specified for TAPSTAR with a hammer drill.
*For anchors, the first drilling is the pilot hole diameter.
Don’t gradually increase the size.

② Thoroughly clean out the dust.
③ Measure depth at approximately +10mm
④ Screw it in and installation is complete.

You can install it with hyper-simplicity and certainty. This is what materials should be like. .
It gave me a feeling close to the emotion I had when using tangless helicoils.

The drill bit also has 5 flutes! It’s evolved dramatically

Honestly, I won’t use any other concrete drill from now on. . .
It’s amazing. It cuts really well and “the holes are clean.”
Buy a longer concrete drill bit.

The holes drill clean and straight.
If you can’t drill clean holes, it becomes “loose and sloppy,” so be careful.
For M8 TAPSTAR, the pilot hole is 7.5φ.

Makita’s hammer drill is insane

Honestly. . . . It just drills so smoothly. The holes just open up so smoothly.
After doing it again after a long time, wow. . . . Was it really this easy?

The hammer drill and drill bit are really excellent.
With sharp blades and efficient tools, you can work reliably—I really felt that.

Once you set the depth, “just screw it in”

It’s seriously done in an instant.
TAPSTAR is truly wonderful! There’s nothing else like it.

One thing that bothers me a bit is “only male threads,”
the protruding part is a bit concerning. I’m also worried about bending it or damaging the threads and socket.
I inserted a silicone hose to protect the threads and socket.

Seriously easy! Absolutely perfect.

With this hammer drill, Bosch drill, and TAPSTAR,
concrete installation is not scary at all. You’ll almost never fail.

If you want to drill holes at a perfect 90°, making a drilling jig will be perfect (*´ω｀*)

It’s really about tools and materials. . . .
In installation, tricks and intuition are needed at the very end.
I deeply realized that if tricks and intuition are needed from the start, the material itself was still in development.
