The Tool Bit to be installed should always provide a 1/4” (6 mm) minimum chip
clearance against the Tool Holder.
Loosen the Clamping Screws and slide the Sleeve Assembly in toward the pipe until
the Tool Bit Shaft is just outside of the pipe face.
Adjust the position of the Tool Bit to the pipe bore by using a combination of:
Control Features
The different hole patterns provided on the Support Block.
The radial feed mechanism of the Tool Block.
Positioning the Tool Bit in the Tool Bit slot.
The Tool Bit should not be extended out of the Tool Bit slot by more than 5/8” (15.9
mm) on the cutting side of the Tool Bit Holder.
Lock the Feed Tube into position with the Clamping Screw.
Check to insure that the Tool Bit is clear of the pipe and that the Feed Pin is re-
tracted.
OPERATION
Slowly rotate the Clamshell to insure that the Counterbore Tool Bit clears the pipe.
Increase the Clamshell RPM to cutting speed. Reference the “Cutting Speeds and
Feed” section of this manual.
