Delta & Triangle Sanding Discs

Delta and triangle sanding discs fit detail sanders to reach into corners and tight spaces.  Hook‑and‑loop backing allows quick changes between grits.

What are delta and triangle sanding discs used for?
These sanding discs are designed for multi-tools and detail sanders. Their triangular shape makes them perfect for reaching into corners, edges, and tight spaces where round sanding pads can’t fit.

How do I choose the right grit for a sanding disc?
Coarse grits (40–80) are best for heavy material removal or stripping finishes, medium grits (100–180) for smoothing surfaces, and fine grits (220+) for finishing and preparing surfaces for painting or varnishing.

How can I make sanding discs last longer?
Avoid pressing too hard — let the tool do the work. Keep the surface clean, and replace discs when the grit becomes clogged or worn. Using the right grit for each stage of sanding also prevents premature wear.
