The CoroDrill® 818 is a newly-developed counterboring device that features both a TXN insert and an iLock tip seat interface for increased process security. This is a durable and stable tool that is very simple to use and is highly adaptable thanks to its adjustability. The 818 is easy to implement in applications, and utilizes an improved chip-mouth design resulting in greater chip evacuation.

A timing mark allows for easy drill tube positioning and the TXN insert permits superior chip control with all materials as compared to standard counterboring devices. The CoroDrill® 818 is fitted with a single insert for push and pull boring, and buyers will be very impressed with the efficiency and reliability provided with use of this device.
