Reaming Shell Drilling Tools Core Drilling Long Service Llfe DCDMA Sizes

Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability.It can also be used as a stabilizer for drill bit,capable of protecting hole diameters of drill bits from damaging.

As the core bit diameter and diameter of the core tube is very small, so that the gap between the hole and the core tube is more narrow, so that the water blocked which is easier to cause the blocked drill. Reamer is a short columnar body, the upper and lower part of the steel part of the thread with the drill bit and the core tube connected to the middle part of the diamond is covered with super-hard material, the outer diameter is slightly larger than the diamond drill diameter (0.5 mm To about 2 mm), the carcass side surface has a water way, so that water can pass through.

This reaming shell is mainly made up of steel body, polycrystalline diamond and carbide powder.
