TetraForce-Cut – Bushing – AH7025
IMPROVE PRODUCTIVITY AND TOOL LIFE
During pating-off of S35C bushings on a CNC lathe, the previous tool suffered from unstable chip control, particularly during widening operations.
By adopting Tungaloy's TetraForce-Cut with the wear-resistant AH7025 grade, designed for reliable chip evacuation and enhanced stability in steel machining, the user achieved consistently smooth chip handling.
This resulted in a 40% increase in productivity and a 15% longer tool life compared to the prior tool, significantly improving both operational efficiency and process stability.
