Aggressive Milling Power, Field-Proven Designs

Whether you’re cutting plugs, scale, cement, or junk, Bull Dog milling tools are built to bite. Our lineup includes hard-hitting Junk Mills with optimized circulation paths and customizable carbide dressings for every application, from flat-bottom to tapered string designs.

 

When stability counts, the Free Roll® Stabilizer uses roller bearings sized to casing ID to keep your tools perfectly centered and reduce lateral wear, making it ideal for production well work and reverse circulation. For offset or restricted-ID situations, the Offset® Mill is engineered to mill eccentrically, enlarging your cut zone without damaging the casing. With high-torque capacity, field-proven durability, and made-to-order flexibility, Bull Dog mills are built to chew through the tough stuff — so you can stay on schedule and on target.
