These bits are designed specially for small diameter holes, 1-3/8" and smaller. When cutting small holes, large reinforcing rods and heavy psi concrete can wipe out bits quickly. Drillco has formulated the S.M. Series matrix to achieve maximum speed and performance. Ideal when a carbide bit encounters rebar and can not complete the job. Available in 5/8"-11 threads.

Drillco uses its own specially formulated matrix to produce its C.S. Series. The C.S. Series is designed for heavy duty coring applications and works best in heavily reinforced concrete. For 30 years the C.S. Series has been the preferred core bit for contractors who do a great deal of core drilling and prefer speed along with longevity out of their core bits.

The C.S.B. Series is preferred by contractors whose initial cost is a factor. The C.S.B. Series is an exceptional value for those with light to medium coring applications.
