hole exceeds the practicality of a core bit
• Premium carbon steel with heat treatment improves
core strength for maximum durability and extended life
• Fast penetration rate thanks to chisel-shaped carbide
teeth
• Wide land and substantial core thickness makes bits
durable even in large hammers
• Centering tip reduces bit walking for exact spot drilling
• Three wide flute ejects debris fast
