TT81^SERIES Turning Grades for Steel

Features and Benefits

• This is an upgrade to existing TT81^SERIES turning grades for high-speed and high-feed applications in steel
• Latest CVD coating features brand new surface treatment and coating combination for superior anti-chipping
• Ensures excellent wear resistance due to the stable alumina coating layer
• More consistent performance and up to 80% longer tool life!
• Minimized chemical reaction between the coating surface and the workpiece during machining
• Two-tone insert color promotes easy detection of worn edges
• All Black/Gold inserts have been assigned new item numbers
• All gold inserts will be phased out as stock is depleted

TT8105 (All Gold) --> TT8105B (Black/Gold)

• Maximum wear and crater resistance
• First choice for high speed, continuous cutting

TT8115 (All Gold) --> TT8115B (Black/Gold)

• For high speed continuous, to mild interrupted cutting on steels
• Excellent wear resistance and heat resistance

TT8125 (All Gold) --> TT8125B (Black/Gold)

• For general use on steels, including interrupted cuts
• Very good combination of wear resistance and toughness

TT8135 (All Gold) --> TT8135B (Black/Gold)

• Tough carbide substrate ideal for heavy turning or severe interruptions
• For a wide range of medium to roughing applications at lower speeds
