-----CUTTING TOOL LIFE IMPROVEMENT
I am thinking of going for Cryogenic Treatment for our HSS cutting Tools, such as Drills & Reamers. Please let me know the life increase value with this process. If any new technology has evolved, please let me know.

Cryogenic treatment of HSS cutting tools for increased wear resistance is an ideal application. One of the benefits is that the it is a "through metal" treatment -- not a surface coating or surface modification. So if you are able to resharpen the tools, the benefits will continue to be in effect after the re-sharp. Generally speaking, the cost is significantly below a coating also. It is not unusual to see an increase of 150% to 300% of the "pre-treatment" life. Some people report even greater results, but I feel that a doubling of life is a reasonable expectation. Be sure to use a "deep cryogenic treatment" to -300 °F - very gradually applied with an extended dwell (e.g. 24 hours). Also, be sure there is a post temper or heating cycle.
