3-Piece Carbon Steel Sanding Disc Set

The DeWalt LA021 set contains three inclined sanding discs that double as angle grinder polishing pads. They are designed for curved wood shaping, sanding, polishing and surface finishing on hardwood, softwood and raw logs. The carbon steel construction with a golden anti-rust finish provides wear resistance for heavy-duty use. This set suits woodworkers and DIYers needing efficient curved surface shaping.

Check angle grinder size and arbor fit

Each disc has a 3.34 inch outer diameter and a standard .62 inch arbor hole. The set fits most standard 4 inch and 4.5 inch angle grinders with regular arbor sizes. Verify your grinder matches these dimensions before ordering. No extra adapters or fittings are required for compatible tools.

Thermals noise and power draw in normal use

The lightweight, well-balanced design enables steady grip and precise control during sanding, shaping and polishing operations. The inclined face design works effectively on curved surfaces and uneven lumber. Dense sharp grinding teeth maintain stability and resist dulling under continuous heavy-duty work. Power draw and noise depend on the angle grinder used.

Questions about this item

What comes in the DeWalt LA021 set and do I need any extra parts to mount it?

The set includes three 3.34-inch carbon steel sanding discs with a .62-inch arbor hole that fits 4-inch and 4.5-inch angle grinders directly, so no additional adapters are required.

How do I choose between the discs in this three-piece set?

All three discs share the same 3.34-inch diameter, .62-inch arbor and carbon steel construction, so they are interchangeable for curved wood shaping, sanding and polishing tasks.

What does the 3.34-inch diameter mean when the disc is on my grinder?

The 3.34-inch outer diameter works on standard 4-inch and 4.5-inch angle grinders, giving an inclined face that reaches into arcs and curved surfaces for shaping and finishing wood.
