1" X 4-1/4" Carbide Tip Whirley Bit

Whirley Bits on this page have a 1" x 4-1/4" shank. Additional shank sizes are available here.

These bits utilize hollow steel so air flow can continuously keep the drill hole clear as well as a carbide tip to handle the hardest material. Champion offers hole sizes from 5/8" to 1-1/2" in diameter with lengths available to 48". Champion Chisel Whirley Bits are proudly Made in the U.S.A.
