Recently, CPC has been improving, so I thought I’d push a little harder—like Masuo-san
We’re working on earthquake preparedness! In the midst of that “Makita 40V 20mm cordless hammer drill HR010GZK” I brought one in. Compact and lightweight really is the easiest to use~ Wow—concrete just opens up so smoothly like this….
Tool technology has advanced so incredibly.
Today’s item recommendation
Theme: Stress-free hole drilling and anchor fixing on garage concrete floors and walls.
Problem: I want to drill holes in concrete to anchor a bike lift, large rack, or earthquake-preparedness foundation, but it’s so hard that nothing gets through, and the vibration kills my hands and arms….
Star of the show: Makita 40V MAX HR010GK hammer drill & Bosch X5L SDS-plus
Surprising results: All that previous struggle was for nothing. Literally, hard concrete becomes “tofu,” and holes open up smoothly, as if being sucked in!

In any case, it’s compact. Necessary and sufficient
I wouldn’t call it palm-sized, but “A hammer drill this small?” That’s what I thought. SDS shank * A standard for the shaft that inserts into the tool body to secure bits (drill tips, etc.) used in hammer drills and rotary hammers . Mainly developed by Germany’s Bosch, its greatest feature is one-touch attachment and detachment without tools. For concrete, up to 20mm is possible . This model uses SDS-plus shank * Note: SDS MAX also exists (it’s a completely different size)
Even with the battery attached, it stays this compact. “Bigger doesn’t always mean better” is always true. I’m reminded once again that choosing what’s necessary and sufficient is important.
With the battery it feels hefty, but it’s still lightweight and compact. At 40V max with this size, it’s the best (*´ω｀*)
Minimal waste and simple operation are its charm

Unlike the 18V series “Depth is adjustable with one push” Being able to easily adjust the depth reference is truly appreciated.
The handle lock is “physical shape lock” so it won’t loosen and move. You loosen the dial and fit it into the bumpy position to lock it, so it’s secure.
SDS-plus shank so attachment is just insertion.
Thinking up stuff like this is usually overseas makers, right?
The holes are perfectly round…. Bosch X5L (5-blade) is amazing
Really… I’m amazed, old man. I’m crying every day like Urashima Taro? Lately, concrete holes open so cleanly and easily…. I’m shocked.
The old image of “holes don’t open cleanly, it’s hard to drill” is completely gone.
Literally? Concrete turned to tofu? I’ve heard that line somewhere before…. Stainless steel rolling?
The Tap Starter pilot hole is 7.5mm. * Anchor, that is. I choose longer concrete drill bits.
Concrete turned to tofu!? Slicing through stone with the ultimate rotary hammer drill!
Topic: Recommended tools for effortlessly anchoring heavy garage equipment. Details: To complete our ongoing “Earthquake Preparedness” project in the Mutsuzawa factory, we needed to anchor our heavy tool racks and bike lifts directly into the concrete floor. Drilling into concrete is notoriously difficult; standard drills create a lot of noise and vibration but barely make a dent. To solve this, I invested in a professional-grade rotary hammer drill paired with a high-quality carbide tipped bit (SDS-plus). Verdict: The difference is unbelievable. It felt as if the rock-hard concrete had literally turned into “Tofu.” The drill sank smoothly into the ground in under 10 seconds without needing heavy body weight. High-quality cutting tools never betray you—whether you’re working on a vintage motorcycle engine or custom-building your dream garage!
