The original Magnum Industrial MI-31160 includes 26 two-edge high-speed steel (HSS) blades that sell for USD79 per 10 pieces. However, HSS blades tend to wear out quickly, and their arrangement is not helical. In contrast, the Sheartak spiral cutterhead for the MI-31160 features 40 carbide inserts, each with four cutting edges. Carbide inserts have a lifespan that is 50 times longer than HSS blades, making them a more durable option. Additionally, Sheartak angled the 40 carbide inserts along four helical grooves for a pure shear cut, which results in a superior surface finish. The Sheartak carbide inserts come in a box and sell for USD36 or CAD45. By upgrading to the Sheartak spiral cutterhead, users can achieve better performance and recoup their investment quickly.
