OVERVIEW

Premium Surface Finishing with Walter Wire Cup Brushes

The Walter 13G302 3-inch Wire Cup Brush represents the pinnacle of surface preparation technology for industrial applications. Designed by Walter Surface Technologies, a leader in abrasive solutions, this tool is engineered to tackle the most demanding cleaning and removal tasks on steel surfaces. At the core of its performance is the utilization of top-quality oil-hardened and tempered steel wires. Unlike standard wires that may brittle or break under stress, Walter's proprietary wire treatment ensures that each filament maintains its structural integrity even during aggressive brushing action. This results in a brush that not only cuts faster but lasts significantly longer than competitive alternatives, reducing downtime for tool changes and lowering overall consumable costs.

Precision balance is a critical factor in the design of the 13G302. In industrial environments, operator fatigue caused by tool vibration can lead to reduced productivity and potential health issues. Walter has meticulously positioned the wires to ensure impeccable balance, providing a smooth, vibration-free operation. This allows operators to work for extended periods with greater comfort and control. Furthermore, the brush features an integrated safety supporting ring. This ring controls the flaring of the wires under load, maintaining a concentrated brushing area and preventing premature wire breakage. As the wire wears down, the ring helps maintain a consistent aggressive action, ensuring that the finish quality remains uniform from the first pass to the last.

This specific model comes equipped with an M14 x 2.0 threaded arbor, making it compatible with specific angle grinders that utilize this metric thread standard. It is an ideal solution for heavy-duty cleaning on large, flat surfaces such as steel plates, structural beams, and tank walls. Whether removing heavy rust, scaling paint, or preparing surfaces for coating, the Walter 13G302 delivers reliable, high-performance results. The brush is designed to withstand the rigors of continuous industrial use, making it a staple in shipyards, fabrication shops, and manufacturing facilities where efficiency and safety are paramount.

Investing in Walter abrasives means investing in safety and performance. The 13G302 is not just a consumable; it is a precision tool that enhances the capabilities of your grinding equipment. With its robust construction and thoughtful engineering, it stands as a testament to Walter's commitment to "Only the Best" in surface treatment solutions.

FAQ

This brush features an M14 x 2.0 threaded arbor. Please verify your angle grinder spindle size before purchasing, as this is different from the standard 5/8-11 thread.

This brush uses carbon steel wire. Using it on stainless steel can cause cross-contamination and lead to rust issues (after-rust). For stainless steel, we recommend using a brush with stainless steel wire.

The brush has a diameter of 3 inches (75mm), making it suitable for standard angle grinders.

The safety supporting ring prevents the wires from flaring out excessively under load, which extends the brush life and maintains a safer, more concentrated brushing action.

The description highlights aggressive brushing action and smooth movement with a supporting ring, which is typical of high-performance cup brushes designed for removal. The oil-hardened wire provides stiffness similar to knotted performance for heavy cleaning.

While specific RPM should always be checked on the product label, 3-inch cup brushes are typically rated for high-speed angle grinders, often around 12,000 RPM. Always ensure your grinder does not exceed the brush's rating.

It will physically fit inside the guard of a 4.5-inch grinder, BUT only if the grinder has an M14 x 2.0 spindle. Most North American grinders use 5/8-11 threads, so check your tool first.
