The Holzmann GSM24ECO_230V is an electric tapping machine designed for efficient and precise internal thread cutting in metal workpieces.

It offers a tapping range from M6 to M24 in steel and up to M30 in aluminium, making it suitable for a wide variety of mechanical engineering, metalworking, maintenance and fabrication applications.

With its 1200 W motor, adjustable speed from 0 to 200 rpm, articulated arm and touchscreen control, the GSM24ECO provides a practical solution for workshops that regularly perform tapping operations.

M6 to M24 Tapping Range in Steel

The Holzmann GSM24ECO offers a wide tapping capacity for steel:

M6 to M24

This range covers many of the thread sizes commonly used in mechanical engineering, machine assembly, metal fabrication, maintenance and general workshop applications.

The machine is therefore suitable for both occasional tapping work and repetitive production operations.

Up to M30 in Aluminium

When working with aluminium, the GSM24ECO offers an even larger tapping capacity:

M6 to M30

This extended range increases the versatility of the machine for workshops processing different types of metal.

Powerful 1200 W Motor

The Holzmann GSM24ECO is equipped with a 1200 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 where a three-phase connection may not be available near the tapping station.

Its motor power is particularly well suited to the machine's large tapping capacity, including threads up to M24 in steel.

Adjustable Speed from 0 to 200 rpm

The spindle speed can be adjusted from:

0 to 200 rpm

This allows the operator to adapt the tapping speed according to the thread diameter, material and machining conditions.

Different thread sizes and materials require appropriate working parameters, particularly when moving between smaller threads and larger diameters in steel or aluminium.

Touchscreen Control

The Holzmann GSM24ECO is equipped with a touchscreen for setting the main operating parameters.

Settings such as thread size and tapping depth can be adjusted directly through the touchscreen interface.

This makes machine setup easier and helps provide a more controlled tapping process.

The user interface is available in German and English.

Manual and Automatic Tapping Modes

The GSM24ECO offers two tapping modes: manual and automatic.

This allows the operator to select the most appropriate operating mode depending on the workpiece and tapping operation.

Manual Mode

In manual mode, forward and reverse rotation can be controlled manually.

This gives the operator direct control over the tapping process and is particularly useful for specific or individual operations.

Automatic Mode

In automatic mode, reverse rotation is activated automatically once the preset tapping depth has been reached.

This is particularly useful for repetitive work.

When several identical threads need to be produced, the preset tapping depth and automatic reverse function help provide a more consistent and efficient workflow.

Articulated Arm with 1100 mm Working Radius

The articulated arm of the Holzmann GSM24ECO provides a maximum working radius of 1100 mm.

This large working range allows the tapping head to be moved to different positions across a workpiece without constantly repositioning the workpiece itself.

This is a major advantage when working with heavy, bulky or difficult-to-move components.

Height Adjustment up to 520 mm

The articulated arm also provides height adjustment up to 520 mm.

This makes it possible to adapt the tapping head position to different workpiece heights and workshop configurations.

Combined with the 1100 mm working radius, this provides excellent flexibility for tapping operations.

Tapping Head Swivels by 90°

The tapping head can be swivelled by 90°.

This feature further increases positioning flexibility and allows the machine to be adapted to different tapping configurations.

The combination of an articulated arm and swivelling tapping head offers significantly greater freedom of movement than a conventional fixed-position tapping machine.

Collets with Slip Clutch

The Holzmann GSM24ECO is supplied with a collet set equipped with slip clutches.

This system is specifically designed to accommodate the corresponding taps and provides a practical solution for changing between different thread sizes.

Collet Set Included

The GSM24ECO is supplied with collets covering its main tapping range:

DIN 371:

• M6

• M8

• M10

DIN 376:

• M12

• M14

• M16

• M18

• M20

• M22

• M24

The supplied collet set therefore provides a wide range of sizes for common workshop tapping operations.

Technical Specifications of the Holzmann GSM24ECO

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 workpieces require identical threads, 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 from one position to another across the same workpiece.

Ideal for Large and Heavy Workpieces

With a conventional fixed machine, the workpiece generally has to be positioned beneath the spindle.

The articulated design of the Holzmann GSM24ECO tapping arm allows the tapping head to be moved towards the required working position instead.

With its maximum 1100 mm working radius, the GSM24ECO is therefore particularly useful for tapping large, heavy or cumbersome metal components that would otherwise be difficult to reposition repeatedly.

Optional GSMMS Machine Stand

For a dedicated tapping workstation, the Holzmann GSMMS machine stand is available as an optional accessory.

It provides a suitable support for the electric tapping machine and allows the GSM24ECO to be installed as a dedicated tapping station within the workshop.

Why Choose the Holzmann GSM24ECO?

The Holzmann GSM24ECO electric tapping machine combines a large tapping capacity with excellent flexibility thanks to its articulated arm.

Its M6-M24 tapping range in steel, capacity up to M30 in aluminium, 1200 W motor, adjustable speed up to 200 rpm and maximum working radius of 1100 mm make it a highly versatile workshop machine.

The touchscreen control, adjustable tapping depth, manual and automatic operating modes, slip-clutch collets and 90° swivelling tapping head further improve efficiency when carrying out regular tapping operations.

Electric Tapping Machine for Professional Workshops

The Holzmann GSM24ECO 230V is suitable for metalworking workshops, mechanical engineering, maintenance departments, fabrication shops and other professional users who regularly need to produce internal threads.

With its large tapping capacity, articulated arm and touchscreen control, the GSM24ECO provides an efficient solution for faster, more consistent tapping operations, particularly when working with large workpieces or carrying out repetitive threading tasks.
