With its QuickIN system and restart protection, it combines safety and productivity in everyday use.

A professional FEIN tool distributed by Dagobert Industrie, reliable, robust, ready to use.

Presentation of the FEIN CCG 18-125-12 AS: a high-performance cordless grinder

The FEIN CCG 18-125-12 AS is an 18V cordless angle grinder designed for professionals who refuse to compromise between mobility and power.

It accepts 125 mm discs and features a high-efficiency brushless motor. The result: a no-load speed reaching 9,000 rpm, sufficient for cutting, grinding, and sanding steel, stainless steel, or stone.

With the 12 Ah battery provided, battery life is clearly sufficient for extended work sessions without returning to the charger.

Design and ergonomics of the CCG 18-125-12 AS

FEIN has refined the balance of the machine to reduce fatigue during long-term use. The compact body facilitates work in hard-to-reach areas.

Restart protection is integrated: if the battery is removed while under load and then reinserted, the grinder will not start on its own. A real plus for site safety.

Key highlights to note:

• Soft-start system to limit jolts during startup
• Electronic speed regulation under load to maintain performance
• Side handle adjustable to 3 positions
• Tool-free adjustable safety guard
• Spindle lock system for quick disc changes

Compared to a standard corded grinder like the FEIN WSG 17-125 P, the CCG 18-125-12 AS offers total freedom of movement without sacrificing torque or motor durability.

Technical specifications of the FEIN CCG 18-125-12 AS cordless angle grinder

The FEIN CCG 18-125-12 AS is an 18V cordless angle grinder equipped with a 125 mm disc. It runs at 9,000 rpm at no-load, placing it in the category of high-performance grinders for intensive use.

The brushless motor optimizes energy efficiency and extends the tool's lifespan. Less maintenance, more power delivered to the grinding wheel.

It is delivered with a high-capacity 18 V / 12 Ah battery. This high autonomy is suitable for construction sites where power outlets are rare or absent.

The FEIN AUTOSTOP system automatically stops the disc in the event of a blockage. It is an active safety feature that protects the user and the tool in jamming situations.

The total weight (with battery) remains contained for a machine of this capacity, which limits fatigue during long work sessions.

Applications and areas of use for the FEIN CCG 18-125-12 AS

The FEIN CCG 18-125-12 AS is designed for demanding work on construction sites, in workshops, or for industrial maintenance. Being cordless, it follows the user everywhere without the constraints of a cable.

It excels in grinding, cutting, deburring, and sanding operations on a wide variety of materials. Its 125 mm disc covers the common uses of metalworkers, boilermakers, or locksmiths.

Thanks to its AS (AutoStop) system, it features an automatic disc stop brake. A major safety asset on sites where prevention standards are strict.

Compatible materials and recommended accessories

The CCG 18-125-12 AS works efficiently on:

• Steel and stainless steel, grinding, cutting, deburring weld seams
• Aluminum, surface finishing and light finishing
• Stone and concrete, with a suitable diamond disc
• Composite materials, cutting and sanding with specific discs

Recommended accessories depend on the application. For stainless steel, prioritize discs free of iron and sulfur. For concrete, a segmented diamond disc is essential.

Model	Disc diameter	Voltage	Automatic stop	Main use
FEIN CCG 18-125-12 AS	125 mm	18 V	Yes (AutoStop)	Grinding, cutting, stainless steel, steel
FEIN CCG 18-115-12 BL	115 mm	18 V	No	Light grinding, steel
Makita DGA504	125 mm	18 V	No	Versatile site use
Milwaukee M18 CAG125X	125 mm	18 V	No	Intensive steel grinding

At Dagobert Industrie, we recommend the CCG 18-125-12 AS for all professionals who work on varied materials and cannot afford to switch machines based on the substrate.

Comparison: FEIN CCG 18-125-12 AS versus other 18V cordless angle grinders

The market for 18V cordless angle grinders is dense. Makita, Bosch, Milwaukee, Metabo... all offer competitive models. Here is where the FEIN CCG 18-125-12 AS stands.

The FEIN is distinguished first by its high-frequency brushless motor, inherited from the professional FEIN range. It spins faster, heats up less, and lasts longer than the majority of competing brushless motors in this segment.

The other strength: the FEIN SafetyCell system, which simultaneously protects the battery and the tool against overload, overheating, and deep discharge. This is a real advantage in intensive use.

Model	Brand	Disc	No-load speed	Weight (without battery)	Soft-start	Electronic brake
CCG 18-125-12 AS	FEIN	125 mm	9,000 rpm	1.8 kg	✓	✓
DGA504	Makita	125 mm	8,500 rpm	1.9 kg	✓	✓
GWS 18V-10	Bosch Professional	125 mm	9,000 rpm	2.0 kg	✓	✓
M18 FDAG125	Milwaukee	125 mm	9,000 rpm	2.0 kg	✓	✓
W 18 LTX 125	Metabo	125 mm	9,600 rpm	1.8 kg	✓	✓

On paper, the figures are similar. The difference is felt in use: the FEIN mechanical finish, the quality of the gears, and the robustness of the housing place the CCG 18-125-12 AS a notch above in terms of longevity.

The Metabo W 18 LTX 125 shows a slightly higher speed. But the FEIN compensates with better electronic management and more consistent torque under load.

For daily professional use, the CCG 18-125-12 AS remains a benchmark in this segment. At Dagobert Industrie, it is one of the most popular models for metalworkers and boilermakers.

Included equipment and compatibility with the FEIN 18V range

The FEIN CCG 18-125-12 AS is delivered in a case with everything needed to start immediately on site.

The box content includes:

• 1 CCG 18-125-12 AS cordless angle grinder
• 2 18 V / 6.0 Ah FEIN AMPShare batteries
• 1 ALG 50 rapid charger
• 1 safety guard
• 1 side handle
• 1 quick-clamping nut
• 1 rigid transport case

The machine is compatible with the entire range of FEIN AMPShare 18 V batteries. This shared system allows the same battery to be used on all FEIN 18 V tools: drills, oscillating saws, vacuums.

The AMPShare system is also interoperable with Makita 18 V LXT batteries via a dedicated adapter, which broadens compatibility on construction sites already equipped with Makita.

The 6.0 Ah batteries provided offer sufficient autonomy for prolonged grinding sessions without interruption. The ALG 50 rapid charger charges an empty battery in about 55 minutes.

With two batteries included, you work continuously: one charging while the other powers the machine. A concrete advantage on sites far from an outlet.

FAQ - FEIN CCG 18-125-12 AS

1. What is the disc capacity and no-load speed?

The FEIN CCG 18-125-12 AS accepts 125 mm diameter discs. Its no-load speed reaches 9,000 rpm, placing it in the standard for professional compact angle grinders.

2. How long does the battery last on a construction site?

It is delivered with an 18 V / 12 Ah battery from the FEIN AMPShare range. It is one of the highest capacities on the market in this format.

Concretely, this allows for prolonged grinding sessions without interruption, even on thick pieces or weld seams that need finishing.

3. Is it compatible with other brands' batteries?

The CCG 18-125-12 AS uses the FEIN AMPShare platform, which is compatible with Bosch ProCORE 18 V batteries. This is a concrete advantage if you already have Bosch Professional batteries on the site.

Outside of this cross-compatibility, other brands' batteries (Milwaukee, Makita, Metabo...) are not interchangeable.

4. Is the soft-start system really useful?

Yes. The soft start avoids wrist jerk at startup, especially with a diamond or flap disc. It is an important safety point for fragile workpieces or finishing tasks.

5. What is the difference compared to the FEIN CCG 18-125-10 AS?

The main difference is the battery capacity: 12 Ah on the CCG 18-125-12 AS versus 10 Ah on the previous version. Autonomy is therefore approximately 20% higher.

The motor, speed, and dimensions remain identical. The choice depends solely on the expected intensity of use.

6. For which materials is this grinder suitable?

It is suitable for steel, stainless steel, cast iron, and light masonry with the appropriate discs. For stainless steel, remember to use a specific disc free of iron and sulfur to avoid surface contamination.

It is not designed for continuous cutting of thick tile or reinforced concrete: prefer a corded grinder of higher power for these intensive uses.
