Clear protective safety face shield with plastic construction, weighing 22 grams, designed for Delta electric grinders port size 17.5-19mm to guard against dust, splashes, and projectiles during metalworking, grinding, and chemical handling tasks.
Clear Plastic Face Shield for Delta Electric Grinders - 17.5-19mm Port Protection

This transparent protective cover is a dedicated safety accessory for Delta brand electric grinders, designed to fit a specific thread port size between 17.5 and 19 millimetres. Weighing 22 grams, its plastic construction offers a lightweight yet effective barrier for the entire face during demanding industrial tasks. The primary function is to guard the operator against a range of airborne hazards common in workshops and processing environments. It is explicitly suited for applications such as steel heat treatment, boiler ash handling, electroplating polishing, and grinding wheel operations, where the risk of splash or projectile injury from materials like acids, alkalis, oils, chemical liquids, metal solutions, iron filings, or glass fragments is present. By covering the face, it aims to prevent damage from these harmful objects, functioning as a shield against splashes, impacts, arc flash, and chemical exposure.
Features and Construction

This safety product is built with a focus on practical protection for specific machinery. Its design centres on creating a physical barrier between the operator and workplace hazards without obstructing the task at hand.
Material and Build
The shield is made from plastic, contributing to its stated weight of 22 grams. This material choice results in a cover that is both transparent for necessary visibility and capable of forming a solid protective layer. The construction is tailored to perform core protective functions as stated: anti-splash, anti-impact, anti-arc, and anti-chemical. It acts as a safeguard against the direct contact of harmful substances and flying debris with the user's face, which is a critical safety consideration in the listed industrial processes.
Size and Practical Fit
The key dimensional specification is the electric grinding thread port, which measures 17.5 to 19 millimetres. This measurement is crucial for ensuring a secure and correct attachment to the compatible power tools. The product is not a universal fit but is designed specifically for a range of Delta grinder models, including the 100, 200, 275, 285, 300, 395, 398, 400, 770, 800, 3000, 4000, 8100, 8200, 8220, and 4200 series. This precise compatibility means it is intended as an accessory for these particular tools to enhance their safe operation.
Uses and Placement

The shield has defined applications based on the potential hazards of certain industrial and workshop tasks. Its use is tied to environments where material splashing or projectile generation is a risk.
Event or Professional Use
In professional settings, this cover is applicable for operations involving Delta electric grinders where extra facial protection is warranted. This includes metalworking shops, fabrication units, plating facilities, and boiler maintenance areas. The listed tasks—steel heat treatment, boiler ash delivery, electroplating polishing, and grinding wheel grinding—are all scenarios where hot materials, fine particulates, or corrosive liquids could be propelled towards the operator. The shield serves as an additional layer of personal protective equipment (PPE) in these contexts.
Everyday Home Use
For serious DIY enthusiasts or home workshop users who own one of the specified Delta grinder models and engage in heavy-duty tasks like metal grinding or polishing, this cover adds a face safety component. It is particularly relevant for projects that generate significant dust, sparks, or fine debris, such as restoring metal furniture or working with composite materials. However, its application is fundamentally linked to the use of the compatible power tool and the nature of the work being performed.
Benefits and Buying Value

The value of this product lies in its targeted safety function and tool-specific design. It addresses a clear need for enhanced operator protection in defined hazardous scenarios.
Reuse and Low Maintenance
As a durable plastic accessory, the shield is built for reuse across multiple work sessions. Maintenance is straightforward, primarily involving cleaning the transparent surface to ensure clear vision and checking for any damage that might compromise its protective integrity. Its simple attachment mechanism via the threaded port allows for easy placement and removal from the grinder as needed.
Why Choose This Product
This clear protective cover is chosen for its direct compatibility with a wide range of Delta electric grinders, offering a tailored safety solution for those specific tools. It provides a defined, measurable benefit: full-face protection against a catalogued list of industrial hazards including chemical splashes and flying fragments. For users operating the supported Delta models in the stated applications, it represents a dedicated accessory that integrates with their existing equipment to address a specific safety gap, focusing on preventing facial injury from the front during tool operation.
