Casing Cutters
When the entire drill string cannot be recovered, Roschen casing cutters are the perfect tool to minimize loss.
Single blade "Bradley Style" and dual blade casing cutters are available in all industry standard sizes.
Casing Cutter Assembly
The casing cutter assembly is for cutting steel pipe underground. Our unique downhole hydraulic pipe cutter applies smooth constant pressure onto three knives via a piston assembly, thereby assuring clean and rapid cutting. Once the device is lowered to the desired depth where water pressure can be applied, it begins rotating. The cutting blade normally makes cuttings before water pressure reaches to 150 to 200 PSI. CDGâ??s casing cutter assembly includes AW, BW, NW and HW.
Casing Cutters Functions:
1. When a string of casing is stuck in a drill hole , a portion of it can be salvaged by cutting the casing above the stuck zone with a casing cutter. The casing can be cut at any desired point in the string.
2. The cutter connects directly to the drill rods and the pressure of the circulating water against a piston forces the steel or tungsten carbide tipped cutters out against the casing. After the casing is cut the pressure is released and the cutters retract.
Features:
1. Used for cutting NW casing or HRHP/H/HM rod at any point in a drill hole when the entire string can not be retrieved.
2. NW NWL HW HWL rod box connection.
3. Each knife is made of crushed tungsten carbide.
4. To make these cutters more practical, our downhole hydraulic pipe cutters are designed with fully interchangeable internal components.
5. In fact, the only difference of various casing cutter assembly is the size of heavy duty cutter body. This means there are fewer parts in need of repair and replace. Therefore, you need not to buy and stock casing cutters' components in order to run and maintain cutter with multiple sizes.
Applications:
1. Upon lowering the assembly, the cutting lugs are retracted inside the body by the spring. With low rotation (25 rpm) initially, the cutting lugs are forced out using water pressure, 1 380 kpa (200 psi). A drop in pressure indicates that the cutting operation is complete.
2. AW, BW, NW, HW/HWT casing cutter all is available.
3. Used for Odex drilling system
4. Pipe casing for difficult rock formations

Description: Marine Casing Cutter is built to withstand extreme shock encountered in cutting strings of uncentralized conductor pipe. Due to the unique construction of this tool, the rugged cutter arms expand outward up to 5 times the diameter of the tool body and achieve maximum stability under all types of adverse cutting conditions, including hard spots, eccentricity, interrupted cuts, etc. For example, the 13-3/8 casing cutter measures only 11-3/4 diameter and cuts all ranges and weights of pipe through 60.

More Super Hard provides a variety of milling tools, from face milling, shoulder milling, chamfer milling to milling straight and T-slots. PCD tools have been widely used in aluminum production. The system is characterized by the minimum work required to increase the number of mounting teeth, long service life and low roughness. However, if areas of surface roughness are required, or even rougher than the very good standard surface produced during PCD processing, PCD tools often reach their limits. This can be remedied by using PCD auxiliary tools that can be adapted individually to the application or retroactively installed in existing standard tools.
Marine Casing cutter is one of tools which cuts the casing internally. It uses water horsepower to drive cutters work, It has structure reasonable and convenient maintenance, faster cutting speed. When cutting multi-layer non-concentric casings, It could bear drastic shaking. Strong cutter arms can extend to 5 times as much as body diameter, so that get max stability performance under all kind of disadvantage cutting condition( including hard point, concentric, cutting discontinuity), such as 13-3/8" marine cutter body diameter is just 11-3/4", but the max cutting range of pipes reach 60".

We introduced Opti-Cut cutting teeth from Backer Hughes,and each cutter had the optimal geometry, so that no matter how the cutting teeth are arranged on the cutting or milling tools, the blade edge or tip is facing up. When the teeth wear out, new blades and tips will appear. The new cutting teeth have a total of 16 blade tips and 8 blade edges. Applications range from tubing fishing, packer milling, sleeve milling, casing/pipe cutting, and milling to wherever extremely sharp cutting edges are required.
