Deep Hole U Drills-HMD System

The HMD modular deep hole drill can drill up to 10 times the diameter while still maintaining accuracy and stability. This deep hole capability is made possible by the system’s unique high-speed steel (HSS) pilot drill design. By pre-cutting and continuously maintaining the cut, the pilot drill provides excellent drill guidance and centering even at deeper depths. With the modular design of the HMD system, you can build different drilling combinations using a variety of standard components (especially the extension rod design, which can increase the drilling depth while reducing your processing costs). You can modify the drill to produce a specific diameter within the limitations of each drill, and the drill can be quickly replaced with just one mounting screw. The HMD system’s internal coolant supply cools the insert cutting edge and helps with chip evacuation, further improving the quality of the hole and the life of the insert. Make sure your tool is stable and connected correctly with the HMD modular deep hole drilling system.
