20 in / 50 cm	.325″	.063″ (1.6 mm)	81	Rapid Micro 3 semi‑chisel, low‑kickback	3 ⁄ 16″ (4.8 mm)

Why Choose 26 RM3?

Low‑kickback comfort links meet ANSI B175.1 to reduce the risk of rotational kickback.
Semi‑chisel teeth stay sharp longer than full‑chisel in dirty or frozen wood and are easier to hand‑file.
Oilomatic® lubrication groove funnels bar oil to rivets, lowering heat and stretch for fewer tension checks.
Taller‑profile drive links add mass for smoother operation on high‑torque, mid‑size engines.
Factory pre‑stretched—less adjustment during break‑in, more cutting time in the field.
