Carbide Whirley Bits

Whirley Bits, also known as concrete doweling drill bits, are used mainly in highway expansion construction.

These bits include Whirley Bits, DKR-32 Bits, UT-7 bits, and CP bits (CP-9A, MRD-9, 6LHD). Please call for sizes not listed below.

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.
