Crown drill head with carbide for flexible shafts, for metal and ceramic pipe

This crown drill head is designed for drilling through solid obstructions in metal and ceramic pipes. Typical tasks are cement deposits, failed liners, heavy scale build-up and severe root intrusion that block or restrict the pipe bore.

Cutting action

Combined with a circular chain knocker it forms an effective cutting system: the drill head works forwards while the carbide teeth on the rim break down the deposits.

PVC pipes

We do not recommend this drill head for PVC pipes, as the carbide bits fused to the head can damage the material. Used together with a plain circular chain it is possible – take particular care at bends and transitions, where the risk of damage increases.

For PVC we offer the Croco drill head. It works less aggressively and is equally suited to PVC, metal and ceramic pipes.

Construction

The drill head is made from high-grade stainless steel and is therefore corrosion-resistant even in permanently wet sewer conditions. It is secured to the shaft with three set screws, which gives a stable connection under load.
