Patented carbide tip controlled self centering when starting holes; aggressive angles for faster drilling. Patented flute design for rapid dust removal, reduces clogging and increases penetration speed. Short drill head forces drilling dust into flute. 140° cutting tip provides more cutting surface than competitor’s tip, reduces breakout in through-hole applications; centering point prevents walking.
I had to drill 8 holes in a ceramic tile (used without impact so as not to break the tile), the drill bit was rounded in the center of hole 4 I'm sure this won't be a problem if you're using percussion and drilling in concrete/brick, but I bought carbide tipped drill bits expecting them to be stiffer.
