Capacity M3-M36 (M42)
The machine is formed by a tilting arm being by means of a pneumatic spring, said arm being fitted through an intermediary union to a radial arm being revolvable around 360º. The assembly is secured to the workbench by means of a base plate being provided with a post clearing the whole table area.
The motor head finds itself at the end of the tilting arm and is apt to always move at right angles with respect to its working area.
The motor speed, the tool automatic lubrication and the depth control can be adjusted by means of a display placed on the cover of the electronic board case.
Lifter
The working height of the machine can be increased by 160 mm. in order to thus be in a position to work at different heights.
Electric motor
High Frequency Electric motor. Power 1,5 Kw. Single phase (220V or 110). Motor supply voltage: 200-240 V. 50/60 Hz. Less speed: 40 rpm – Highest speed: 900 rpm
VH
The ROSCAMAT SHARK VH (Vertical & Horizontal, 4x90º) includes an easily-handled articulated head assembly that allows the motor to be positioned in four 90° positions and tap in horizontal and vertical direction.

Quick-change Toolholders
A wide range of tapholders, all of them with or without clutch, apart from other quick holding fixture for different tools, such as drills, sinking tools, threading dies, socket wrenches, etc. are available. Tapholder with safety clutch so that it slips when it reaches the hole bottom. Type 1 Ø19 mm: capacity range M2-M16 (for modules 900, 500, 320) Type 2 Ø31 mm: capacity range M6-M30 (for modules 140 & 75) Type 3 Ø48 mm: capacity range M14-M42 (for module 40)Tapholder without safety clutch for holding different tools with cylindrical shank and driving cube. Type 1 Ø19 mm: capacity range M2-M16 (for modules 900, 500, 320) Type 2 Ø31 mm: capacity range M6-M30 (for modules 140 & 75) Type 3 Ø48 mm: capacity range M14-M42 (for module 40)
Modular system
The modular system is apt to be fitted to the electronic motor and consists of a 6 quick-change planetary speed reducers giving 6 different speeds and torques. The speed can be thus adapted to every thread type.

Automatic Tap Lubrication
Inside the radial arm the cutting oil reservoir is located. This is used for lubricating the tool during the tapping operation. The lubrication time according to the metric size to be done is adjusted by means of one of the upper head buttons.
Depth control
By means of an internal systemr, the machine controls the vertical arm position (Axe Z) in mm. so that you can control at which desired depth you wish to tap.
