3M Rubber Slotted Expander Wheel 28348, 5 in x 3-1/2 in 5/8 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 Slotted Model

The 3M Rubber Slotted Expander Wheel 28348 offers consistent performance with its unique design. This model is engineered to use centrifugal force to grip abrasive belts securely during grinding tasks.

Its compatibility with 3M Inline Sanders and Match & Finish Tools makes it a versatile choice for finishing applications. The model number 28348 ensures you get the exact product designed for these tools.

Precise Dimensions Included

This expander wheel measures 5 inches in diameter by 3-1/2 inches wide, providing ample surface area for effective sanding. The 5/8 inch arbor hole allows for easy mounting on compatible equipment.

These exact dimensions help users select the right wheel size for their 3M Inline Sander or Match & Finish Tool, ensuring a proper fit and optimal performance during use.

Soft Rubber Finishing

Featuring a soft 25-durometer rubber, this wheel is designed to create a fine finish on surfaces like stainless steel. The softness helps the wheel conform to the workpiece for smooth results.

Radiused edges on the wheel reduce transition lines, improving the quality of the finish. This makes it ideal for applications requiring a clean, professional appearance.

Secure Belt Grip

Unlike pneumatic wheels, this 3M expander wheel uses centrifugal force to hold abrasive belts firmly in place. This method provides more consistent and reliable belt tension during operation.

Using centrifugal force eliminates the variability of air pressure in pneumatic wheels, resulting in smoother sanding and less belt slippage for better productivity.

Pack Size And Usage

This product is sold as 1 each per case, making it easy to order exactly what you need without excess. The single-unit pack size suits both individual users and small shops.

Recommended for stainless steel finishing, it works well with 3M coated abrasive belts and Scotch-Brite Surface Conditioning Belts. Use it with the 3M Wheel Adapter Kit for best results.
