How to select a carbide brush cutting blade

(1)— MULTI-USE BLADES: 48,60,80, 100 & 120 teeth blades are handy for ANY job such as: Pruning, Hedging, large Limb cutting as well as for Brush
& Brambles. MORE teeth means more aggregate cutting surface (more carbide)and therefore less seizing in limbs and less tearing and ripping when hedging
(best at high rpm’s)……
(2)— BRUSH & BRAMBLES specialized BLADES: Our 36 & 40 teeth blades are more tailored for Brush & Brambles due todeeper teeth cavities. LESS teeth are required to create deeper wider teethcavities, that can grab & cut more brush material per blade spin (best atalternating rpm’s).
