TetraMini-Cut – shaft – AH7025
IMPROVE PRODUCTIVITY AND TOOL LIFE
In external ring grooving of shaft made from SCM435, conventional tools suffered from inconsistent tool life and poor chip evacuation, impacting both process stability and productivity.
By switching to Tungaloy's TetraMini-Cut featuring the AH7025 grade, designed for wear resistance and reliable performance on steel materials, the customer achieved stable machining and trouble-free chip control.
This led to a remarkable 150% improvement in productivity and doubled the tool life, with parts processed per cutting edge increasing from 500 to 1,000 pieces. The successful results have prompted broader implementation across other part sizes.
