Powerroc 6-1/2" Milled Tooth Tricone Bit Soft Medium Formation Foundation Construction Drilling

A milled tooth bit features steel teeth machined directly from the cone, making it more economical and ideal for soft to medium formations. A TCI insert bit uses tungsten carbide inserts pressed into the cone, offering longer wear life in harder, more abrasive formations. For construction and foundation drilling in soft to medium ground, the milled tooth bit is the more cost-effective choice.

This bit is ideal for foundation piling, bored pile drilling, geotechnical investigations, and general construction site drilling where 6-1/2 inch boreholes are required in soft to medium formations such as clay, sand, shale, and soft limestone.

The milled tooth geometry is optimized specifically for soft to medium formations, providing aggressive cutting action and faster rate of penetration compared to bits designed for harder rock. This translates to shorter drilling time and lower operational costs on construction projects.
