ORTC – One Revolution Tube Cutter
These tools have been designed for cutting both ferrous and non-ferrous tubes, that are commonly found, in heat exchangers, boilers and condensers. Our standard tool is adjustable from 1”-6” (25 mm-155 mm). Longer reach tools are available in 10” (254 mm) increments. The tool is designed to be used with a hand or ratchet wrench only. Impact wrenches should never be used with these tools. The Cutting of the tube is based on the eccentric principle, where the cutter bit moves out to the tube wall as the cutter is rotated. Continued clockwise rotation wil puncture and cut the tube in one revolution. Simply rotating the tool counterclockwise closes the bit and the tool can be removed from the tube.
Push Type Tube Cutters
Our PTTC tube cutters (now available form 1/2” up to 4” O.D.) offer new features to make it the most versatile cutter available. The cutter blade depth can be adjusted to allow the tube to be cut through. The cutter blades are made out of the HSS what assure long life time (when used with proper cutting speed) A single blade is used in cutters from PTTC-82 to PTTC-254.
The PTTC-254 is also available with 2 blades. The cutter from PTTC-315 up to PTTC-902 are furnished with two blades. The front pilot mounted under the cutter keeps the cutter in the center of the tube and prevent the cutter to be jammed as the chips must go forward into the tube. Also available as tube trimmer.
PTTC is also available as Push Type Tube Trimmer.

MWTTC Manual Wheels Tube Cutter
MWTTC – Manual Wheel Type Tube Cutter, designed to cut or partially cut the tubes in the center support sheet of condensers, similar in design to those manufactured by Trane, Carrier and JCI.
The MWTTC has adjustable wheel travel that accurately controls the amount of tube wall the operator can cut. Typically 98% or less is easily set up. The MWTTC comes as standard with 120” reach (3m). On request we can manufacture up to 196” reach (5m).
We recommend our MCP-100 Manual Collet Puller as a companion tool to the MWTTC, this allows quick and trouble free stub and tube extraction.
