With the Makita 194305-9 pin socket attachment, you can quickly and effortlessly loosen jammed flanges and lock nuts on your angle grinder. When a cutting disc binds during heavy metalworking, a standard manual pin spanner often lacks the necessary grip. This sturdy socket connects directly to a 1/2" impact wrench or ratchet, delivering optimal break-away torque without damaging your tool or locking nut. Designed with a precise 25 mm pin spacing and 35 mm diagonal layout, the pins seat securely in the flange holes without slipping. You change discs smoothly and get right back to work.
