【DIYツール紹介】makitaハンマドリルでコアドリル２種比較　サンコーテクノvs ユニカ　鉄筋入りコンクリを切削したい素人の失敗と成功　#コンクリート

There are many situations where you need to drill holes in concrete. Surprisingly, the hammer drill and core drill you normally use can handle the job. However, be sure to carefully consider the type of drill before making your selection. As an amateur, I couldn't resist trying it. I tried cutting reinforced concrete with a drill designed for plain concrete. While it wasn't impossible, it was quite difficult. (Note: This doesn't mean that Sanko Techno's drills are inferior; I'm just an amateur and don't know the details.) The Unika's 18,000 yen price tag isn't just for show. lol Watch the video to find out why. I've made this video fast-paced so that even those who aren't interested in drills can enjoy it. The second half of the video also includes some amateur tips on how to use it. If you're interested in using a core drill, or are undecided about whether to buy a plain or reinforced concrete drill, be sure to check out this video. Sorry, I just checked, and the Unika is also priced at 16,000 yen on Amazon. [Product Information] 🔸 Sanko Techno All-Core Drill L150 LV65SDS 🔸 Unika Single-Function Core Drill E&S for Dry Diamond, DC Type, SDS Shank, 65mm ES-D65SDS The Makita hammer drill I used was the HR2470F. While it's an older model, it's very convenient because it offers both impact drilling mode and non-vibration drilling mode.
