H – Retrievable Reamer Assembly
TIME Limited’s Retrievable Wedge assemblies are manufactured in Canada with 4140 steel, a heat treated, stress relieved material, to ensure the best quality product.
Why do we use a reamer assembly?
- Ensures a smooth transition from the parent hole to the wedge deflection
- Ensures a smooth deflection in the drill hole
- Ensures hole is at the proper gauge diameter to continue coring
- Reusable
Using a Retrievable Reamer
To ensure the reamer assembly drills in the correct hole and follows the wedge deflection, it is important to put added pressure on the bit and drill at a faster than normal penetration rate.
* This product is normally purchased with H RETRIEVABLE WEDGE
