3M 77720 Rubber Slotted Expander Wheel: Versatile Finishing Tool

The 3M 77720 Rubber Slotted Expander Wheel is a highly efficient and versatile tool designed for precision finishing tasks. Engineered to utilize centrifugal force, this wheel excels in gripping abrasive belts during grinding operations, making it an ideal choice for a variety of applications. Crafted with soft 25-durometer rubber, the wheel offers exceptional conformability, perfect for tasks such as stainless steel finishing. Its radiused edges further enhance performance by reducing transition lines and ensuring a smooth finish.

Features and Specifications of the 3M 77720 Wheel

The 3M 77720 Rubber Slotted Expander Wheel is available in three diameter sizes—3, 3.4, or 5 inches—and comes with two center hole diameters, ensuring compatibility with various 3M Inline Sander and Match & Finish Tools. The wheel is mounted using a 3M Wheel Adapter Kit, providing a secure fit. Its innovative design uses centrifugal force for a more consistent and efficient grip compared to traditional pneumatic wheels. This feature not only improves performance but also enhances safety during use.

Practical Applications of the 3M 77720 Wheel

Ideal for stainless steel finishing, the 3M 77720 Rubber Slotted Expander Wheel is a key component in achieving professional-grade results. When mounted on a 3M Inline Sander or Match & Finish Tool, it allows for a two-step finishing process. The coated abrasive belt 777F, 120 grit, is used to set the grain and remove defects, while the Scotch-Brite Surface Conditioning Belt, A Med, blends the surface to a #4 finish. This comprehensive approach ensures a high-quality finish every time. The wheel's ability to get into tighter spaces and achieve a tighter grade pattern makes it a valuable tool for both small and large finishing projects.
