Multi-Function Tool Drills, Chamfers, Thread Mills Holes
The MT drill from Carmex is designed to drill, chamfer and thread mill a hole in a single operation. Made with solid carbide, the two-flute drill/thread milling cutter, with 45-degree chamfering, reduces cycle times by combining operations and eliminating tool changes.
Ideal for mass production operations, the tool 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 appropriate for aluminum and cast iron, producing a high-quality thread surface. Featuring internal coolant channels, the tool is constructed for long life over multiple applications. It is available in a variety of configurations and sizes.
The multi-function tool is said to be an effective way to promote production economy, the company says. It is designed not only to save tool-change time but enable manufacturers to achieve more predictable results and improved quality control.
Let's face it. When most shops go looking for process improvements, turning is seldom at the top of the list. Sure, many shops these days are doing fine work in such areas as reducing lathe setup, combining milling and turning operations on a single machine, and automating workpiece handling functions. But for all the talk of high speed machining and other milling and drilling process improvements, precious little of that kind of thinking is being applied to the turning process itself.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Recent tap geometry refinement and advances in coating technologies have made the chip-less, cold-forming operation suitable for a wider range of workpiece materials.
