How Does It Work?

As the rotating tool is fed into the hole, the front cutting edge deburrs the top of the hole by cutting a 45° chamfer. As the tool feeds into the part, the blade is forced into the body and slides in the blade window.

When the blade is in the hole, only the ground sliding surface touches the hole protecting it from damage while the tool is fed through the part. There is no need to stop or reverse the spindle.

When the blade reaches the back of the part the coiled spring acts with the control bolt to push it back out into cutting position. The back edge is deburred and chamfered as the tool is withdrawn. When the blade is again in the hole, the tool can be rapid fed out and on the next hole.
