The Holzmann GSM16ECO_230V is an electric tapping machine designed for efficient and precise internal thread cutting in metal workpieces.
Its tapping capacity ranges from M3 to M16 in steel and up to M20 in aluminium, covering many of the thread sizes commonly used in mechanical engineering, metal fabrication, maintenance and assembly applications.
With its 600 W motor, adjustable speed from 0 to 312 rpm, articulated arm and touchscreen control, the GSM16ECO provides a practical and versatile tapping station for the workshop.
M3 to M16 Tapping Range in Steel
The Holzmann GSM16ECO offers a wide tapping range for steel:
M3 to M16
This capacity covers both small internal threads used for mechanical assemblies and larger thread sizes frequently required for metal fabrication and maintenance work.
Its ability to start from M3 also makes the GSM16ECO particularly suitable for workshops regularly working with smaller thread diameters.
Up to M20 in Aluminium
When working with aluminium, the tapping capacity increases to:
M3 to M20
This extended range increases the versatility of the GSM16ECO for workshops processing different metal materials and a wide variety of components.
Powerful 600 W Motor
The Holzmann GSM16ECO is equipped with a 600 W S1 motor and operates on a 230 V / 50 Hz power supply.
The single-phase 230 V supply makes installation easier in many workshops without requiring a three-phase connection close to the tapping station.
The motor is designed to provide the performance required for the machine's tapping capacity of up to M16 in steel.
Adjustable Speed from 0 to 312 rpm
The spindle speed can be adjusted from:
0 to 312 rpm
This allows the operator to adapt the tapping speed according to the tap diameter, material and working conditions.
The maximum speed of 312 rpm is particularly useful for the smaller thread sizes covered by the GSM16ECO.
Touchscreen Control
The Holzmann GSM16ECO is equipped with a touchscreen for setting the main tapping parameters.
Settings such as the thread diameter and tapping depth can be configured directly through the touchscreen.
This electronic control simplifies machine setup and makes it easier to adjust the operating parameters when changing thread sizes or workpieces.
The user interface is available in German and English.
Manual and Automatic Tapping Modes
The GSM16ECO offers two operating modes: manual and automatic.
The operator can therefore select the most suitable mode depending on the workpiece and the type of tapping operation being carried out.
Manual Mode
In manual mode, forward and reverse rotation are controlled manually by the operator.
This provides direct control over the tapping process and is particularly useful for individual operations or workpieces requiring greater operator control.
Automatic Mode
In automatic mode, reverse rotation is activated automatically once the preset tapping depth has been reached.
This function is particularly useful for repetitive tapping operations.
When several identical threads have to be produced, the preset depth and automatic reverse function help provide a faster and more consistent workflow.
Articulated Arm with 1030 mm Working Radius
The Holzmann GSM16ECO features an articulated arm with a maximum working radius of 1030 mm.
This large working area allows the tapping head to be moved between different positions on the workpiece without constantly repositioning the workpiece itself.
This is particularly useful when working with heavy, large or cumbersome components.
Height Adjustment up to 400 mm
The articulated arm also provides height adjustment up to 400 mm.
The position of the tapping head can therefore be adapted to different workpiece heights and workshop configurations.
Combined with the 1030 mm working radius, this provides excellent positioning flexibility.
Tapping Head Swivels by 90°
The tapping head can be swivelled by 90°, further increasing the versatility of the machine.
This makes it possible to adapt the tapping head position to different working configurations and improves accessibility when tapping certain components.
The combination of an articulated arm and swivelling tapping head offers considerably more freedom of movement than a conventional fixed-position tapping machine.
Collets with Slip Clutch
The Holzmann GSM16ECO is supplied with a collet set equipped with slip clutches.
The system is specifically designed for tapping operations and allows taps of different sizes to be fitted according to the required thread diameter.
Collet Set Included
The GSM16ECO is supplied with collets covering the main thread sizes within its working range.
DIN 371:
DIN 376:
The supplied equipment therefore covers a wide range of common workshop tapping applications.

Ideal for Small and Medium-Sized Threads
With its M3 to M16 tapping range in steel, the GSM16ECO is particularly suitable for workshops mainly working with small and medium-sized internal threads.
Its maximum speed of 312 rpm also makes it well suited to smaller thread diameters.
For applications requiring threads larger than M16 in steel, the Holzmann GSM24ECO is the more powerful model in the range.
Designed for Repetitive Tapping Operations
One of the main advantages of an electric tapping machine with an articulated arm is its efficiency during repetitive operations.
When several identical threads need to be produced, the adjustable tapping depth and automatic reverse function help provide a more consistent workflow.
The articulated arm also makes it easier to move the tapping head between several tapping positions on the same workpiece.
Practical for Large and Heavy Workpieces
With a conventional fixed tapping machine, the workpiece generally needs to be positioned underneath the spindle.
The articulated design of the Holzmann GSM16ECO tapping arm allows the tapping head to be moved towards the required working position instead.
With a maximum 1030 mm working radius, the GSM16ECO is therefore particularly useful for large, heavy or cumbersome metal components that would otherwise be difficult to reposition repeatedly.
Optional Holzmann GSMMS Machine Stand
The Holzmann GSMMS machine stand is available as an optional accessory for the GSM16ECO.
It provides a dedicated support for the machine and makes it possible to create an independent tapping workstation within the workshop.
Why Choose the Holzmann GSM16ECO?
The Holzmann GSM16ECO electric tapping machine combines a versatile tapping range with the flexibility of an articulated arm.
Its main advantages include its M3-M16 capacity in steel, up to M20 in aluminium, 600 W motor, adjustable speed up to 312 rpm, 1030 mm working radius and 90° swivelling tapping head.
The touchscreen control, adjustable tapping depth, manual and automatic operating modes and slip-clutch collets further improve efficiency when carrying out regular or repetitive tapping operations.
Electric Tapping Machine for Professional Workshops
The Holzmann GSM16ECO 230V is suitable for mechanical workshops, maintenance departments, metal fabrication shops and professional users who regularly need to produce internal threads.
Particularly well suited to small and medium-sized tapping operations, the GSM16ECO combines an M3-M16 capacity in steel with the flexibility of an articulated arm and the convenience of touchscreen electronic control.
