As regards performance unit R-500 can be considered identical with unit R-400, with the advantageously bigger working range thanks to the longer arms. The machine consists basically of the following elements: radial arm, lockable elbow joint, tilting arm and head. The compressed-air motor is coupled to the latter.

Through the foot and by means of three M8 screws the machine can be fixed to a table or workbench. Such attachment can also be obtained by means of a simple clamp. The radial arm and the tilting arm revolve about themselves. The latter tilts therewith always maintaining the perpendicularity to the foot reference plane.The machine incorporates an air servicing unit (filter + regulator + lubricator) for the correct operation of the motor.

The modular system consisting in a series of 7 quick-change modules (reducers) is provided for coupling to said motor. As a result of this 7 output speeds (90, 170, 300, 550, 750, 1050, 2100 rpm) are available thus allowing to adapt the tap speed to every type of thread.

The handle allows to balance the tilting arm and to position it at the operator's convenience. The modular system admits the quick-change tap holders with or without safety clutch depending on the intended job (blind or through holes). Threading capacity from M2 up to M24 (M27).

The modular system provides for a new concept in the use of articulated armed threading machines. Driven from a single motor, seven different speed modules are available with their relevant power torques. The seven quick-change speed modules provide the speed and torque for each threading type, from M2 to M24 (M27) threads

The ROSCAMAT 500 can be supplied with an articulated head (C-26N). This bracket of easy handling can be set in four different positions 90º apart.

A wide range of tapholders, all of them with clutch and without it, apart from other quick holding fixtures for different tools, such as drills, sinking tools, threading dies, socket wrenches, etc are available. · Toolholder with safety clutch:  so that it slips when it reaches the hole bottom.

Type-1 Ø 19 capacity range M2-M16 (for modules 300, 550, 750, 1050) Type-2 Ø 31 capacity range M14-M27 (for modules 90 and 170) · Toolholder without clutch: for holding different tools with a cylindrical shank and driving cube. Type-1 Ø 19 capacity range M2-M16 (for modules 300, 550, 750, 1050) Type-2 Ø 31 capacity range M14-M27 (for modules 90 and 170)

All ROSCAMAT units (400, 500 i 500RH) can be supplied with automatic tap lubrication system. The system is comprised of a regulating valve and a lubricant reservoir, and is actuated by the compressed-air system itself. When starting to tap the oil or liquid flow rate can be regulated for the purpose of lubricating the tap during the operation.
