The Bosch Professional EXPERT S470 Combi Blocks are hand sanding sponges designed for finishing and preparatory sanding on wood and painted wood surfaces. Delivered as a three-piece kit (Medium, Fine, Superfine), these compact 69 × 97 × 26 mm blocks combine a tear-resistant foam core with Bosch’s Surface Structure abrasive to deliver uniform pressure, consistent abrasion, and a long working life compared with conventional sandpaper. The sponge body slightly contours to profiles and edges, so it follows curved or milled surfaces where flat sheets can’t reach — making the Combi Block especially useful for window frames, door edges, furniture profiles and other shaped timbers.
Each block pairs an abrasive coating bonded to a flexible foam that resists tearing and clogging. That strong, flexible bond is one of the product’s key design points: it keeps abrasive grains working against the surface rather than flaking off, which both extends useful life and reduces consumable waste. Bosch advertises significantly longer wear life (up to five times longer than some earlier abrasive papers in their range), which means fewer replacements during a job and a smoother sanding experience overall. This longevity is particularly helpful when stripping old paint or smoothing new filler before finishing.
The Combi Block is purpose-built for hand sanding tasks: it offers a rounded side that follows profiles and an angled/sharp edge for tight corners and glass-adjacent work. That combination makes the block versatile — you can work large flat faces and then switch orientation to access creases and sharp transitions without changing tools. The medium, fine and superfine grits let you step sanding from material removal to final finishing without swapping brands or pad sizes, simplifying the workflow and helping achieve a refined surface ready for paint or varnish.
Because the blocks are small, they’re comfortable for one-handed, controlled sanding and reduce finger fatigue versus folded sheets or awkward sanding tools. The 69 × 97 × 26 mm footprint balances reach and control — big enough to cover surface area efficiently, small enough to manoeuvre into corners. They’re recommended for dry sanding of softwood, painted surfaces on wood, and general hand sanding where a shaped, durable abrasive is preferred. Packaged for tradespeople and DIYers alike, the EXPERT S470 Combi Blocks are an economical and durable upgrade to standard hand sanding consumables.
