Tri Tool Model 601-3 Machines

The Heavy Duty SBCM Series of low profile clamshells are split-frame lathes that produce rapid, reliable severing and beveling of in-line tube and pipe. Smaller lathes have the ability to split in two for mounting on either side of in-line 1/8" pipe to 3" tube in order to perform precision severing and/or beveling.

SBCM Series
machines offer secure collet type clamping that not only provides self-centering, but also prevents distortion or damage from clamping forces with full support on Schedule 5-10 pipe or tube.

SBCM Series machines can be configured for clean-room use (No Lead) and are protected by tough Nickel plating that makes them easy to clean and decontaminate.

SBCM Series machines require a short perch length for operation and are sized to cover a wide range of cutting applications. Bits can be specified to provide optimal cutting results on specific materials.

Tri Tool Model 601SBM to 612SB Machines

The Small SB Clamshells are utilised in a wide variety of roles from tube and pipe production to maintenance in power and processing plants. The models in this group cut from 1/4" through 12" tube and pipe. These lathes may be equipped with self-centering mounting pads for quick, easy mounting, or equipped with adjustable mounting pads for out-of-round pipe or precise centering. Star wheels on the tool modules provide incremental tool bit feed for controlled cut depth.

All small SB clamshells (except the 602TSB) offer machining accessories for socket weld removal and counterboring.

Each clamshell within the small SB group provides specific features and benefits.

Models 601SBM and the 602.5SBM offer tool modules that require minimal axial (along the pipe) or radial (around the pipe) clearance.

The Model 602TSB is designed for performing weld cut-outs on boiler tubes and offers tool modules requiring the lowest radial clearance of any clamshell.

Models 604SB-612SB offer tool module options for a broad range of pipe sizes.

The small SB group may be driven by different power sources to match any work requirement. Their ease of use and dependability has made them the favorite of plant maintenance, welding, and production personnel throughout the world.

Tri Tool Model 616SB to 648SB Machines

The large SB Lathes offer the precision of the small SB's, with the power to cut large, heavy-wall pipe in the most demanding applications.

The large SB clamshells produce otherwise unattainable levels of accuracy and control, critical to pipe welding operations in heavy industry and power production. Because of the clamshell's power and superior stability, many industries depend on this machine for new construction, in-place maintenance, component replacement, decommissioning and production.
