The Science Explained
Engineered Angles Of Attack
Since the 1970s, mining/construction cutter drums have used the same style tooth. Those drums are a much larger diameter and have angled tooth holders to keep the point of the tooth taking the impact, head-on. They were never designed to take side impact. Since power rakes have a small diameter drum, impacts happen on the side of the cutter tooth, not from a head-on direction. Bottom line, it's not the right tool for the job.
This style tooth was only designed for head-on impact. Plus, mining/construction machines are only designed to cut in one direction, unlike power rakes. That's why the basic design hasn't changed, until now.
Every Power Rake maker welds the same basic conical teeth straight upright—no attack angle, zero protection. Rocks hit sideways, shear the carbide braze joint, tooth fails. ALMOST 100% SIDE IMPACT!
Standard Factory Bit. The basic design is used by every attachment manufacturer on the market.
Carbide on the Soilcon tooth is back up by steel. The factory bit has nothing backing it up.
Impact from the side is the main point of failure.
With nothing supporting the tip, it breaks off. Game over.
Attack angles are built into the Soilcon Tooth. Since the carbide is backed up by steel, it can take much more abuse, resulting in substantial increase of useful life.
