TetraMini-Cut – valve – AH8005
IMPROVE TOOL LIFE
During external grooving of SUS304 valves for a new solar water heater component, the previous tool suffered from limited tool life, leading to frequent insert changes and downtime.
By adopting Tungaloy’s TetraMini-Cut with AH8005 grade—featuring a high-hardness, wear-resistant coating designed for stable machining of stainless steel—the manufacturer achieved a significant improvement in tool longevity.
The number of parts produced per cutting edge doubled from 150 to 300, realizing a 200% increase in tool life and enabling more efficient, reliable mass production.
