Review on HritHcoxi Concrete Tungsten SDS Plus Drilling by Tim Evans

Durable Tungsten Drill Bits

I wanted to drill LED lights in front of my house, but I couldn't do it because I didn't have the right tools. After a little research, I realized I needed concrete drills. The good thing is they work with both my regular hand drill and my rotary drill the smallest drill bit for his project and it matched the anchor really well.The drill bits have a wavy design.When the drill bit is rotated the curves of the shank pull naturally the broken drill bit dust out of the concrete and take care of it n for a nice, clean finish .
