The newly introduced MT Drill from Carmex is designed to drill, chamfer and thread mill a hole in a single operation. Constructed of solid carbide, the 2-flute drill/thread milling cutter, with 45-degree chamfering, reduces cycle times by combining operations and eliminating tool changes.


Suitable for mass production operations, the MT Drill features both right- and left-hand internal threads, and the same tool can be used for blind- or through-hole drilling. The optimized carbide grade is ideal for aluminum and cast iron and produces a high-quality thread surface. Featuring internal coolant, the new MT tool is constructed for long life over multiple applications. It is available in a variety of configurations and sizes.

According to Jim White, national sales manager for Carmex USA, "High-quality multi-functioning tooling represents an excellent means of achieving production economies. The new MT Drill not only saves tool change time but enables manufacturers to achieve a more predictable result and improved quality control. The MT Drill is another example of Carmex's leadership through experience in thread milling."
