Presentation of the FEIN AGSZ 18-90 LBL AS pneumatic straight grinder

The FEIN AGSZ 18-90 LBL AS is a pneumatic straight grinder designed for grinding, deburring, and finishing tasks in demanding industrial environments. It accepts 180 mm discs and develops a rotation speed of 6,500 rpm.

Its pneumatic power supply makes it particularly suitable for environments where electricity is prohibited or discouraged, ATEX zones, damp workshops, and heavy maintenance sites.

Design and ergonomics of the AGSZ 18-90 LBL AS

FEIN has designed this tool with an elongated straight body, which facilitates work in hard-to-reach areas: tubes, profiles, and congested parts. Handling remains stable even during prolonged use.

The LBL (Low Vibration) absorption system reduces operator fatigue during long sessions. This is a strong differentiator compared to standard pneumatic straight grinders without damping.

The AS (Auto-Stop) technology automatically cuts rotation in the event of a disc breakage or blockage. An active safety device, not just a simple protective cover.

• Disc diameter: 180 mm
• No-load speed: 6,500 rpm
• Straight shape for restricted access
• Integrated vibration reduction (LBL)
• Automatic safety stop (AS)
• Robust construction for continuous industrial use

At Dagobert Industrie, we offer this grinder to professionals looking for a reliable, secure, and comfortable tool for intensive work cycles.

Applications and fields of use for the FEIN AGSZ 18-90 LBL AS

The FEIN AGSZ 18-90 LBL AS is a pneumatic straight grinder designed for finishing, deburring, and grinding work in confined spaces. Its straight shape and small footprint allow it to reach areas inaccessible to conventional angle grinders.

It is aimed at professionals in metallurgy, boilermaking, industrial maintenance, and mechanical engineering. These sectors demand precision, endurance, and reliability, criteria that FEIN integrates as standard in this machine.

Materials and tasks suitable for this tool

The AGSZ 18-90 LBL AS effectively processes a wide range of materials and operations:

• Steel and stainless steel: deburring, weld grinding, surfacing
• Aluminum and non-ferrous metals: finishing machined parts
• Cast iron: dressing raw surfaces
• Composite materials: light rectification work

Its integrated suction system (LBL) makes it particularly suitable for environments where dust must be controlled: closed workshops, sensitive areas, and work on stainless steel or aluminum.

The rotation speed and pneumatic power allow for the use of grinding wheels, carbide burrs, abrasive discs, and brushes adapted to each application. The tool is suitable for both serial work and occasional maintenance interventions.

FEIN AGSZ 18-90 LBL AS vs other pneumatic straight grinders: comparison table

The FEIN AGSZ 18-90 LBL AS is positioned in the high-end segment of pneumatic straight grinders. To better understand its strengths, here is a direct comparison with representative competing models on the market.

Model	Manufacturer	No-load speed	Grinding wheel diameter	Air power	Noise level	Typical usage
AGSZ 18-90 LBL AS	FEIN	18,000 rpm	Ø 90 mm	~500 W	Low (LBL)	Steel/stainless grinding, precision deburring
Druckluft-Geradschleifer GSL 6	Bosch	25,000 rpm	Ø 6 mm (shank)	~180 W	Medium	Small parts, light finishing
9ST1021 straight grinder	Chicago Pneumatic	20,000 rpm	Ø 76 mm	~400 W	Medium	Deburring, general grinding
G2E100 straight grinder	Atlas Copco	18,000 rpm	Ø 100 mm	~450 W	Medium-high	Heavy industry, site work

The FEIN AGSZ 18-90 LBL AS stands out for its reduced noise level thanks to LBL (Low Noise / Low Vibration) technology. This is a concrete advantage in intensive production environments.

Unlike the Bosch GSL 6, it accepts 90 mm grinding wheels, which gives it a significantly higher material removal capacity on steel and stainless steel.

Compared to the Atlas Copco G2E100, the FEIN remains compact and easier to control during prolonged use, with ergonomics designed to limit operator fatigue.

At Dagobert Industrie, we recommend the FEIN AGSZ 18-90 LBL AS for workshops that prioritize precision, durability, and acoustic comfort in demanding metal applications.

Accessories and equipment compatible with the FEIN AGSZ 18-90 LBL AS

The FEIN AGSZ 18-90 LBL AS accepts 90 mm straight grinding discs with a 20 mm bore. This is the standard format for pneumatic straight grinders in this category.

For steel work, flap abrasive discs or cutting-off wheels are mounted. For stainless steel, specific iron-free and sulfur-free discs are preferred to avoid surface contamination.

Common compatible accessories:

• Cutting-off discs Ø 90 mm, cutting steel, stainless steel, aluminum
• Grinding wheels Ø 90 mm, dressing and deburring on metals
