tiger Electronic Machine

roscamat tiger large

The machine itself consists of a radial arm joint to a tilting arm balanced by means of a pneumatic spring. The head member and the electric motor are located at the end of the tilting arm and is adapted to always move at a right angle with respect to its working area.

Through the base and by means of three M8 (120º) screws the machine can be fixed to a table or workbench. Such attachment can also be obtained with the use of a simple clamp.

The speed is regulated by means of a variator board located in the "electronic box casing". The turning motor speed and the optional automatic lubrication  and depth control are adjustable by means of two seperate buttons located on top of the "radial arm". The speed can therefore be adapted to every thread type.

The modular system is attached to the electric motor (220V or 110V), this is a series of seven quick-change gearbox planetary reducers which give different speeds with their correspondent torques. This makes it possible to adapt the speed and torque to each type of thread.


Tiger Lifter








The height can be adjusted to give an extra 130mm clearance.


VH ( Vertical Horizontal)

Tiger V-H Head







There is an option to have a vertical/horizontal head assembly, which allows the head to be positioned in four 90° positions. Allowing the operator to tap in both horizontal and vertical directions.



Working Area

Roscamat Tiger       Radius: 1020 mm - Height: 535 (660) mm

Tiger Area

Roscamat Tiger V/H Radius: 1160 mm - Height: 535 (660) mm.


Quick Change Tooholder

tap chucks




A wide choice of tapholders are available, either with or without clutch, as well as other quick change adaptors for different tools, such as drills, sinking tools, threading dies, socket wrenches etc.Tap holders with clutch are used on blind holes so that when the tap reaches the bottom of the hole it slips, to prevent snapping the tap. Tap holders without clutch for holding different tools and for tapping through holes.


Type 1 Ø19 mm: capacity range M2 - M14 (for modules 1050, 750, 550, 300 rpm).

Type 2 Ø31 mm: capacity range M6 - M30 (for modules 170 & 90) 


Modular System






There are seven different speed modules available. The seven quick change speed modules provide the speed and torque to match each thred size from M2 - M27 (M33).

Automatic Tap Lubrication (Optional)






The automatic tool lubrication system is attached to the lower part of the radial arm. If it is not preinstalled on the machine it can be attached later. The lubrication time is counted in seconds and adjusted using the potentionometer on the upper part of the arm.


Depth Control (Optional)

depth control





The depth control system can only be fitted at the factory when ordering. It is controlled by an electronic system located within the frame. There is a control box where you can set the thread depth in mm.
