What it is
A universal tap-and-go twin-line head from SGZIOO, supplied with seven thread adaptors, including M8 × 1.25 LH, M10 × 1.25 LH, M10 × 1 LH and 3/8-24 RH. The listing says you can insert new line straight through the eyelets without taking the head apart, and rates it up to 10,000 rpm. When we checked in October 2026 it showed as unavailable, with only a handful of reviews.
Will it fit?
Check your gearbox’s arbor thread against the adaptors. M10 × 1.25 left-hand is the most common on European petrol brush cutters; small electric trimmers often use M8 or their own clip-on heads and won’t suit it. Use the line size your manual recommends (line size guide).
Using it
Tap the head on firm ground at full throttle to release line. To reload, push line straight through until the ends are even and twist to wind. If it stops feeding, the line has usually welded or tangled inside — see line won’t feed.
Alternatives
The very similar LADAMI tap-and-go head has aluminium line exits; the Oregon Lightning Load Pro is a better-documented branded option. Compare in the best brush cutter heads.
