Description
Version:
Tool for combined production of bore, chamfer and thread in a single work step. Pre-drilling is no longer required. The innovative centre cutting edge geometry makes this tool a specialist in thread production in hardened and hard-to-machine materials. The TiAlN high-performance coating ensures the longest possible tool life, especially in hardened steels up to 63 HRC. All tools have left-hand cutting and are suitable for right-hand and left-hand threads.
Note:
Always use with cooling lubricant emulsion. (Fat content minimum 8%). In the case of steels >45 HRC: can only be used with compressed air!
Can also be used for thread size MF4×0.5.
