Description of DEWALT ๐ฉ DW5225 4-6 Inch Carbide
The product is 1/4x6 Perc Drill Bit. Easy to use. The product is manufactured in China. ROCK CARBIDE tip maximizes carbide surface contact for longer bit life. Four flute design cleans debris out for fast, efficient drilling. Three flats on shank eliminate bit slipping in chuck.
I was looking for a durable bit to drill plaster/concrete in my house. This drill bit got the job done without breaking and withstood the heat of drilling into such a hard surface.
Made in Germany For drilling 20 concrete anchors for my pergola. Very fast with a Ryobi rock drill bit, it only takes 10-15 seconds to drill about 4 inches deep and only one drill bit is used to complete all the anchors. Excellent quality. I will buy this brand again for the next project.
I think it's better for masonry but I need it for tile. The tip is not sharp and will not slip on the surface of a smooth tile. I had to drill 1/4 inch holes in the tile. So, where I could, I found suitable places to drill through the mortar. On the grout it stays better in one place. But it also goes through tiles; I used it for this. I just have to be very careful to manually keep it centered on a smooth surface at startup. But it really comes through and holds up very well. Good carbide. Itโฆ
