GRS® GraverMach AT

Description

GRS is a global brand and market leader in the development of tools for jewellery makers, engravers, and allied industries, specialising in the manufacture of precision hand engraving and setting tools as well as related equipment for industrial and business users.

Designed for professionals, the newest GRS GraverMach AT model offers enhanced power, faster impact speed, and improved control, all packed into a more streamlined and portable design. These upgrades provide greater versatility for users seeking both precision and ease of transport.

The GRS GraverMach AT is a new generation pneumatic system that gives you increased versatility and control when engraving, setting, or even when using a compatible rotary handpiece.

The GraverMach AT features an advanced air logic system that allows for precise power control using either the Airtact handpiece or the foot pedal.

With the Airtact handpiece, power is activated by touch, eliminating the need for additional moving parts on the handpiece itself. Additionally, two precision regulators and a dedicated dial allow seamless switching between hand and foot control, ensuring high performance, accuracy, and comfort across a wide range of creative tasks.

The upgraded GraverMach AT units are equipped with high-quality brushless DC motors, enhancing the tool’s durability and operational lifespan. Brushless motors are known for their efficiency, reliability, and reduced maintenance needs compared to traditional motors.

Additionally, the strategic mounting of the motors protects them from potential damage due to oil or water infiltration, making the tool more resilient in various working environments. This design choice not only extends the life of the motor but also ensures consistent performance, even in more demanding conditions.

A separate speed and power control has also been added, meaning users can easily adjust their cutting speed while accessing full power through either the foot pedal or hand-actuated Airtact handpieces.

It is suitable for use on metal, wood, glass, leather, and other materials.

This new version of the GraverMach also has a redesigned, larger foot pedal, ensuring comfort and durability.

Delivering high-quality results, it offers between 400rpm and 6,100rpm (revolutions per minute) and a dual-stage precision air regulator. However, the handpiece used will determine the ideal setting.
