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.

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

PRODUCT FAQ

  1. What materials can the 3M™ Rubber Slotted Expander Wheel work on?

    The rubber slotted expander wheel is designed to be used on a wide variety of surfaces, including metals like aluminum and steel, along with plastics and composites.

  2. Can you explain how using the 3M™ Rubber Slotted Expander Wheel benefits me when compared to other grinding options?

    Sure thing! One great advantage of the rubber slotted expander wheel is that it conforms well to irregular surfaces as it grinds. Additionally, this makes for more even pressure distribution across the surface being worked on which helps prevent overgrinding or leaving scratch marks behind.

  3. How long does the abrasive material last in regular use?

    Because each application can be so different based on various factors such as cement composition and wear time, there isn’t one simple answer that fits all cases. However, we’ve found that typically they’ll last quite a while without needing replacement – just remember to routinely check your progress during your project!

Soft Conformable Rubber, Radiused Edges

The 3M™ Rubber Slotted Expander Wheel is designed to be mounted on a 3M™ Inline Sander or 3M™ Match & Finish Tools with the help of a 3M™ Wheel Adapter Kit. This expander wheel is made of soft 25-durometer rubber, which makes it conformable for applications such as stainless steel finishing. The radiused edges of the wheel help reduce transition lines as the tool makes passes across the work surface.

Centrifugal Force Is More Secure

The 3M™ Rubber Slotted Expander Wheel uses centrifugal force to grip the belt, which is more efficient and consistent than conventional pneumatic wheels or tires that rely on the amount of air pressure they are filled with.

The 3M™ Rubber Slotted Expander Wheel comes in three diameters: 3, 3.4, or 5 inches. The smaller diameter tends to obtain a tighter grade pattern and gets into tighter spaces.

Recommended Applications

The 3M™ Rubber Slotted Expander Wheel is ideal for finishing stainless steel when mounted to a 3M™ Inline Sander or 3M™ Match & Finish Tool. To finish stainless steel, follow a 2-step process with or without a weld:

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