Cobra 400 Tube-Prepping Machine: Bevel, Face, and Counter Bore with Power

Versatile Tool for Tube and Pipe Machining from 1 ½” to 6 ¾” OD

The COBRA 400 machine is a mid-size, High Power portable tube-prepping machine, designed to bevel, face, and counterbore most types of tube and pipe work.

This versatile midrange machine utilises torque-reacted mandrels which align themselves on the inside of the workpiece enabling the machine to cover a range of 38.5mm (1 ½”) ID to 172mm (6 ¾”) OD.

The Cobra 400 machine can also be used with Short Locking Units for machining short parallel pipe lengths and fittings.

A heavy-duty worm and spur gear drive system combines a compact head design with smooth reliable power transmission. 

Fitted with either an electric 110/240v or pneumatic motor the Cobra 400 has the ability to withstand the toughest working environments.
