Features and Benefits:
Straight Shank Masonry Drill Bit Groo-V Tip:
Percussion or rotary only, the Groo-V Tip bit makes holes in almost all materials
Engineered for drilling hard materials, these specialized Ram Tip Bits have a serrated carbide tip which penetrates faster up to 50% faster than standard masonry bits
A drill press supported drill motor is recommended for drilling hard metal
NOTE: Because of the differing densities of these materials the number of holes may vary. Slow drilling speeds are recommended and in some cases marble and granite may not be drillable with carbide tools.
Drilling depth: 10"
