Sandvik Coromant is introducing a new range of rigid, high-precision thread cutting tools, CoroThread 266, which is used in the oil, gas and mechanical engineering industries. First introduced is the CoroThread 266 with 22mm and 27mm blades.

The new design of the iLock blade locking interface guarantees thread cutting stability. This not only maintains the rigidity of the blade and the correct thread shape, but also reduces the reject rate. This blade has 3 cutting edges and each has a positioning groove. When installed, a locating slot is located on the raised rail of the new interface of the shims. The rail locks the blade to the correct position in the insert pocket and provides repeatable precision for each thread cutting pass. Proper assembly and precise indexing are available through separate contacts, as the CoroThread 266 blade is only placed on the positioning rail and can be screwed into place at any time. The new rigid rail technology eliminates the phenomenon of blade mismatch and it is impossible to move the blade once it is fixed.
The CoroThread 266 is extremely stable and its rigidity makes it less vibrating during thread cutting, so a good surface quality is obtained. Customer tests have shown that fewer passes are required to machine threaded products; it also reduces machining time on the machine and increases productivity. Each process can ensure that the indexability of the insert is Class E tolerance, with a tolerance of +0.01 mm in the axial direction and +0.05 mm in the radial direction. This allows the new insert edge to maintain continuous cutting with the same precision as the previous cutting edge, improving product consistency.
With CoroThread 266, the cutting load on the insert is spread out without pressure points, and the insert and holder maintain their design integrity. This results in longer tool and toolholder life, shorter downtime for tool change and better production consistency.
In the oil and gas component industry, tests have shown that the indexing accuracy will vary by +0.01 mm in the axial direction. The material used for threaded parts is the high toughness of the Iconel 718. The operator cannot complete the entire thread with just one cutting edge, but can be replaced with the new CoroThread
The 266 blade edge can be cut to the correct diameter with 7 additional passes, and a total of 27 passes complete the entire product, replacing 40 passes at lower rigid clamping.
A comparison test with the previous blade showed significant tremors on the part after machining 4 to 5 parts. These less stable clamping jaws have a normal tool life of 30 parts per blade, while the CoroThread 266 has a life of 50 parts without vibration and a cleaner, better surface quality.
Overall, all tests have proven that the CoroThread 266 rigid clamping thread cutting tool can increase cutting parameters or extend tool life for greater productivity.
