Tregaskiss introduced its Tough Gun TT4A (analog) and TT4E (ethernet) reamers to maximize uptime and weld quality in robotic welding operations.

Both reamers offer a.95HP motor and 236 pounds of lifting force at 95 psi. The cutter blades are resistant to breaking, chipping or cracking.

Features include durable valves and cylinders rated for 10M+ cycles and a wire cutter that can run 1M+ cycles without requiring maintenance. The reamers feature a motor that lasts up to 18M cycles at 80+ psi. A standard motor lubricator supports that performance by extending the life of the motor; it is recommended for use in damp and moisture rich environments.

An anti-spatter reservoir with 20-ounce capacity reduces the need for frequent refills to improve productivity, while a low fluid level indicator sends an alert to the PLC/robot when anti-spatter solution is low.


The reservoir includes a tethered cap and easy-clean filter to protect against anti-spatter contamination, which can also lead to weld quality issues.
