Seco Tools' Drilling Threadmaster (DTM) significantly reduces hole-processing time by drilling, chamfering and threading holes all in one operation. And because the multi-purpose solid thread mill replaces three separate tools, it helps lower tool costs, conserve tool storage space within machine tools and lessen the number of required tool changes during overall part processing.
As compared with tap threading, thread milling generates superior burr-free surface finishes, and the same tool can be used for both left and right-hand threads as well as for different thread tolerances. Various materials and hole diameters can also be thread milled with the same tool for further reductions in tooling inventory.
The DTM’s tip drills holes, so no extra depth is required. As the tool reaches the bottom of a hole, it automatically chamfers the top of the hole diameter. Threads are then quickly and precisely milled through helical interpolation.
DTM is available for applications in cast iron and aluminum. For both materials, the tool will maintain short chip lengths and efficiently channel them up its helical flutes. Threads range from M4 up to M16 with both UNC/UNF and Witworth profiles.
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
