Grind, finish, and polish tight fillet welds, narrow seams, and hard-to-reach metal corners with our specialized fillet weld grinders. Featuring an extremely flat, long aluminum extension arm and low-profile gear head, these tools reach deep into narrow angles and narrow gaps where standard angle grinders cannot fit. Equipped with high-torque electric motors, variable speed electronics for processing stainless steel, and tool-free adjustable guards, they deliver precise stock removal and seamless finishing without damaging surrounding metal surfaces. Ideal for handrail fabricators, tank builders, stainless steel welders, and structural metal shops.
