In the video “Six Secrets of 3M Extract Sandpaper,” Drew Witt from Wittworks dives into the intriguing history and advanced technology behind the popular 3M Extract sandpaper.
This video is a must-watch for woodworkers looking to deepen their understanding of this high-performance abrasive.
Drew begins by highlighting the impressive journey of 3M Extract, which took over a century to perfect. The sandpaper is known for its fast cutting, long-lasting durability, and virtually dust-free operation, making it a favorite among woodworkers.
Rather than focusing on repetitive product reviews, Drew shares six lesser-known facts about 3M Extract, offering viewers a unique perspective.
The history of 3M’s involvement in abrasive technology dates back to 1902, with the company introducing its first sandpaper by 1905.
This early innovation set the stage for continuous improvement, driven by feedback from industrial users. By 1914, 3M had established a research lab dedicated to quality control, a critical step that ensured the company’s leadership in the abrasive market.
Fast forward to the 1980s, and 3M’s development of the Cubitron abrasive, a significant advancement in sanding technology, is discussed.
The real breakthrough came in 1992 with the patenting of Cubitron 2, a precision-shaped abrasive grain. This technology, combined with the expiration of Mirka’s net sanding disc patent in 2015, allowed 3M to create the Extract Cubitron 2 Net Disc by 2021.
Drew explains the science behind the Cubitron 2’s effectiveness, emphasizing its triangular ceramic grains. These grains, similar to carbide in hardness, break down to expose new sharp edges, ensuring a long-lasting and consistent cut.
The key innovation was finding a way to keep these grains standing upright on the sandpaper surface, likely achieved through static electricity.
One of the most interesting revelations is the geometric pattern on the sandpaper, meticulously designed for optimal performance. 3M tested nearly 100 patterns to find the best configuration for cutting efficiency and dust removal.
Drew also credits Mike Taylor from Taylor Toolworks for bringing 3M Extract to the woodworking community. Initially designed for metalworking, it was Taylor’s application to wood that showcased the sandpaper’s versatility and effectiveness, leading to its broader adoption among woodworkers.
The video concludes with practical advice on choosing the right sandpaper for specific tasks. While the Extract 710W Net Disc excels in dust collection, other options like the Cubitron 2 775L might be better suited for applications requiring more durability and fewer holes for dust extraction.
Overall, Drew Witt’s detailed exploration of 3M Extract sandpaper provides woodworkers with valuable insights into choosing and using this advanced abrasive technology effectively.
