REAMER products are manufactured using high-quality synthetic and natural diamonds embedded in a highly resistant matrix. Additional protection from friction-resistant tungsten carbide maximizes lifespan, while the maximum active surface helps limit deviation during operation.
Surface set reaming shells in all common DCDMA sizes are available as stock items. Impregnated reaming shells and reaming shells in full hole profile are also available, though they may require longer lead times.
