Reaming shell

Impregnated and Surface Set Wireline Diamond Reaming Shells With BQ NQ HQ PQ
Roschen reaming shells are made with high-quality, synthetic and natural diamonds, embedded in a highly resistant matrix. They have additional protection made from friction-resistant tungsten carbide to maximize lifespan, and their maximum active surface helps to limit deviation.

Optimized choices:
Surface set reaming shells in all common DCDMA sizes are a stock item. Impregnated reaming shells and reaming shells in full hole profile are also available, but may require longer lead time.


Usage:
1. Available in all standard drilling sizes (A, B, N, H and P).
2. Combination of natural and synthetic diamonds embedded in sections
3. Ring completely covered with diamonds
4. Reliable material and advanced technology

Size Available as followings:
"Q" series: AQ, BQ, NQ, HQ, PQ
