3M Rubber Slotted Expander Wheel 28718, 5 in x 3-1/2 in 1 in Arbor Hole, 1 Per Case

• More consistent performance than pneumatic wheels
• Radiused edges reduce transition lines
• Soft 25-durometer rubber helps to create a fine finish
• Use 3M Wheel Adapter Kit to mount on 3M Inline Sander or 3M Match & Finish Tool
• Uses centrifugal force to grip the abrasive belt

The 3M Rubber Slotted Expander Wheel utilizes centrifugal force to grip abrasive belts while grinding. Use this wheel on a 3M Inline Sander or 3M Match & Finish Tool. It comes in three diameters and two center hole diameters.

Soft Conformable Rubber, Radiused Edges
Our 3M Rubber Slotted Expander Wheel can be mounted on a 3M Inline Sander or 3M Match & Finish Tools using a 3M Wheel Adapter Kit. We designed this wheel with soft 25-durometer rubber to keep it conformable for applications like stainless steel finishing. Radiused edges reduce transition lines as the tool makes passes across the work surface.

Centrifugal Force Is More Secure
This wheel uses centrifugal force to grip the belt rather than conventional pneumatic wheels, or tires, which rely upon the amount of air pressure they are filled with. Centrifugal force is ultimately far more efficient and consistent.

In three diameters of 3, 3.4 or 5 inches, the smaller diameter tends to obtain a tighter grade pattern and gets into tighter spaces.

Recommended Applications
Our 3M Rubber Slotted Expander Wheel is ideal for finishing stainless steel when mounted to a 3M Inline Sander or 3M Match & Finish Tool. Having mounted the expander wheel to the sander using the 3M Wheel Adapter, follow a 2-step process for finishing stainless steel, either with or without a weld:

• The coated abrasive belt 777F, 120 grit, can be used to set the grain and remove defects using the 3M Inline Sander (28339) at 3,500 rpm.
• Use our Scotch-Brite Surface Conditioning Belt, A Med, to blend the surface to a #4 finish.

3M Rubber Expander Wheel

The 3M Rubber Slotted Expander Wheel 28718 offers consistent performance with its soft 25-durometer rubber construction. This model is designed to provide a fine finish while reducing transition lines thanks to its radiused edges.

Ideal for use with abrasive belts, this wheel fits a 1 inch arbor hole and is part of 3M’s lineup for finishing tasks. Its design ensures reliable grip through centrifugal force rather than air pressure.

Precise Size And Dimensions

This expander wheel measures 5 inches by 3-1/2 inches, making it suitable for a variety of finishing applications. The size allows it to reach tighter spaces while maintaining a smooth grade pattern.

Its 1 inch arbor hole fits standard mounting setups, ensuring compatibility with 3M Inline Sanders and Match & Finish Tools. The dimensions support efficient surface finishing on stainless steel and other metals.

Effective Belt Grip System

The wheel uses centrifugal force to grip abrasive belts securely, which is more consistent than pneumatic wheels that depend on air pressure. This ensures steady performance during grinding and finishing.

By relying on this force, the wheel maintains belt tension automatically, reducing the need for manual adjustments. This feature enhances productivity when paired with 3M sanding equipment.

Compatible With 3M Tools

This 3M Rubber Slotted Expander Wheel works with 3M Inline Sanders and Match & Finish Tools when mounted using the 3M Wheel Adapter Kit. This compatibility makes it easy to integrate into existing finishing setups.

Users can follow a two-step finishing process on stainless steel by pairing this wheel with specific abrasive belts, such as the 777F 120 grit and Scotch-Brite Surface Conditioning Belt for a #4 finish.

Pack Size And Usage

The product comes as a single unit per case, allowing users to purchase exactly what they need without excess. This pack size suits both small shops and larger operations requiring precise finishing tools.

Its design and specifications make it ideal for stainless steel finishing, especially when used with 3M’s recommended abrasive belts and tools. This ensures a professional-grade finish every time.
