Description
Angle Grinder Attachment Belt Sander, Mini Belt Sander, Detail Sander for Metal
-
Turn a grinder you already own into a detail sander: install it on a standard 4, 4-1/2 or 5 inch angle grinder in about two minutes
-
Reach corners and gaps a grinder head cannot: the belt sander attachment is built for corner, gap, and flat grinding
-
Finish welds without buying a second tool: polish stainless steel, aluminum, and brass weld seams with the same attachment
-
No slipping mid-job: the grooved drive wheel and high-strength spring keep the sanding belt tracking true
-
Go from rough to fine without extra purchases: two included belts cover both 60 and 100 grit sanding
Buying a dedicated belt sander just to clean up a weld seam or get into a tight corner is overkill when you already own an angle grinder. This angle grinder attachment turns that grinder into a mini belt sander in about two minutes, using the same 5/8"-11 spindle most 4" (10.2 cm), 4-1/2", and 5" (12.7 cm) grinders already have. Every part of the bracket is metal — high-carbon steel body, aluminum alloy end support — so the heat from heavy-duty grinding never becomes a problem. It works as a handheld belt sander the moment it is bolted on, no separate tool to buy.
A dual-bearing design keeps this detail sander running smooth and stable, and a built-in high-strength spring holds steady tension on the belt so it never slips loose mid-pass; the grooved, textured drive wheel does the same job for the belt itself. It handles corner, gap and flat grinding on stainless steel, aluminum, and brass, which makes it just as useful for weld joint polishing as for woodworking or metal rust removal. Two 3/4" x 20.5" sanding belts — one 60 grit, one 100 grit — come in the box, so you can go from rough sanding to a fine finish without buying extra belts first. As a portable belt sander, it goes wherever the grinder goes, on site or on the bench.
