HDD Reamer

A common rule is 1.5–2.0× the product pipe OD, so space is provided while bore stability is maintained.

Soil condition and product size/material should be confirmed first; then reamer type and cutting structure are chosen.

Through-shaft designs, heat-treated alloy steel, and carbide wear surfaces are commonly specified for longer life in hard ground.

Rotary or “shark tooth” cutting actions are commonly offered, so soft soil, hardpan, and cobble can be addressed.
