Have 1/4 inch floor grout that needs to be redone is there a power tool to do this? Not a drentel or anything like that its much to slow. Would a skil saw with a masonry blade work for this? How much needs to be removed or how thick does the new grout need to be so that it will stay in place?

word cross:(
1 a type of bit that is normally used in power tools and is flat on two sides- s _ _ _ _
2 a stationary power tool used for wood turning-_ _ t _ _
3 this type of drill rotates the bit by pushing down on the hand- a _ t _ _ r _ i _
4 a portable electric saw that moves blade in an up and down motion- _ _ _ _ r
5 a stationary power saw commonly used for ripping wood-_ _ _ _ e
6 a saw with a thin blade used to cut circles and curves- _ _ _ i _ _

thanks!
