Bosch 6-piece assortment 5 in. 8-hole hook-and-loop sanding discs

A handy sanding assortment that punches above its weight

I put the Bosch sanding discs through a handful of typical shop tasks—smoothing pine shelves, prepping a veneered cabinet door for finish, and scuff-sanding a painted trim repair—using a 5-inch, 8-hole random orbital sander hooked to a dust extractor. For a small six-pack assortment, these discs handled more than I expected, with predictable cut, solid adhesion, and respectable dust control.

What’s in the pack and how it fits

The assortment includes two discs each of 60, 120, and 240 grit. That spread makes sense for a compact, coarse-to-fine workflow: 60 for taking down mill marks or leveling filler, 120 for refining the scratch pattern, and 240 for pre-finish or between-coat sanding. If you’re tackling a single project or touching up a few pieces, the mix is practical. For an entire room of trim or multiple tabletops, you’ll likely want bulk packs of the specific grits you burn through.

These are 5-inch discs with an 8-hole pattern and hook-and-loop backing. Alignment on my sander was effortless, and the discs stayed put without any edge lift, even after multiple on-and-off swaps. If your sander uses a different hole layout (some older models have 5 holes, and some modern ones use multi-hole patterns), the discs will still spin and cut, but your dust extraction won’t be as effective unless the holes line up.

Abrasive and backing quality

The discs use open-coat aluminum oxide with a resin bond on a flexible paper backing. In practice, that combination hits a nice middle ground:

• The open-coat structure helps keep dust from packing the grain, especially on softwoods and painted surfaces.
• The resin bond holds grit securely enough to resist early shedding, as long as you avoid excess pressure and heat.
• The flexible paper backing doesn’t crack when you bend it around a block or lightly fold for an edge touch-up. I wouldn’t fold them in half and scrub like a detail sheet—there’s still hook-and-loop on the back—but for quick hand-blending at a chamfer, they hold up surprisingly well.

Cutting performance: wood and veneer

On clear pine, 60 grit cut cleanly without wild gouging, flattening planer tracks faster than I expected for aluminum oxide. I found I could shift to 120 after a few passes and erase the 60-grit scratches quickly. The 240 left a uniform, low-sheen surface that was ready for a first coat of finish. On softwoods, 240 grit on a random orbital can still telegraph faint swirls in certain light; a quick hand-sand with the grain solved that.

On a veneered cabinet door (maple veneer over MDF), the discs were controllable and forgiving. The open coat and consistent resin bond made it easier to keep the surface cool and avoid burning through. I stayed light with pressure and kept the sander moving—good practice on veneer regardless of the disc—and 240 grit produced a smooth, even scratch pattern without dulling the edges of the veneer tape.

Painted surfaces and clog resistance

For paint prep, the 120 grit was the sweet spot for scuffing and feathering. It bit well enough into a cured latex trim paint to promote adhesion without chewing through to the substrate. I used 60 grit to level a small patch of filler before repainting; the disc loaded in the immediate filler area—as most papers do—but cleared once I moved back onto paint and wood. A rubber cleaning stick revived the abrasive and extended its life noticeably.

Open-coat discs won’t make gummy paint magically non-gummy, but these resisted loading as well as any mid-tier aluminum oxide discs I’ve used. If you’re grinding through thick, elastic coatings, a mesh or ceramic disc would still be my pick. For everyday scuff-sanding and light removal, these get it done.

Dust collection and surface temperature

With the 8-hole pattern aligned and a vac attached, dust capture was solid. I didn’t see the characteristic “ring” of fines around the pad, and the discs stayed cooler than typical no-hole papers. Compared with multi-hole or mesh abrasives, you’ll get a bit more visible dust on the workbench, but for an 8-hole layout, performance was very good. If you’re sanding indoors, the extraction is good enough to keep airborne dust down to a manageable level.

Longevity and consistency

I cycled between the three grits over several pieces of pine shelving and trim offcuts. The 60 grit maintained its bite long enough to be practical; I didn’t see the grain glazing over prematurely, which can happen with heat or excessive pressure. The 120 grit struck the best balance of cut and life—plenty of control, quick scratch refinement, and no surprise dull spots. The 240 grit, as expected, wore faster when used aggressively on paint but held up nicely on bare wood and between coats.

One thing I appreciated was the consistent scratch pattern across the face of the disc. I didn’t encounter “hot spots” or random deep scratches from oversized grains. That uniformity reduces the time you spend chasing ghosts when you move up grits.

Hook-and-loop adhesion and disc changes

The hook-and-loop backing on these discs is strong without being overly aggressive. They release cleanly from the pad, and I didn’t notice the backing delaminating when peeling them off—a common failure point on bargain papers. If you change discs frequently, peel slowly along the pad to preserve both the hooks and the pad’s interface. I swapped each disc a handful of times without losing grip.

Where these shine—and where they don’t

Strengths:
- Reliable, predictable cut on wood, veneer, and painted surfaces
- Good dust extraction with an 8-hole pad and vacuum
- Flexible paper that tolerates light hand blending without cracking
- Hook-and-loop that holds tight yet peels cleanly
- Thoughtful grit spread for small to medium tasks

Limitations:
- Only two discs per grit; bigger jobs will outpace the assortment
- 240 is a sensible top grit, but finish-focused users may want 320/400
- Not the fastest option for heavy paint removal or dense hardwood stock removal compared with ceramic abrasives
- Dust capture is good, but not at the level of multi-hole mesh systems

Tips for best results

• Align the holes carefully to maximize dust extraction and keep discs cool.
• Don’t skip grits. Even a quick pass at 120 after 60 saves time at 240 and reduces swirls.
• Use light pressure and let the abrasive cut. If it stops cutting, clean with a rubber stick or swap discs.
• On veneer, keep the pad flat and the machine moving; rely on 240 for the final pass.
• For painted trim, scuff with 120, wipe down, and finish with 240 if you want a smoother base for finish coats.

Value

For a six-pack, the discs offer good value as an all-in-one set to tackle common shop and jobsite tasks. You’re paying for convenience and consistency more than bulk economy. If you end up relying heavily on one grit—often 120 in my shop—buying a larger box of that specific grit will make more sense long term. As a starter set, travel kit, or quick resupply, this assortment is easy to recommend.

Bottom line

The Bosch sanding discs deliver dependable performance in a compact assortment. They cut cleanly, shed dust efficiently for an 8-hole paper, and finish to a predictable scratch pattern—traits that matter more in day-to-day work than exotic abrasive chemistries. They won’t outpace high-end ceramic or mesh discs on aggressive tasks, and the six-disc count limits them to small and medium jobs. But if you need a straightforward, compatible set for wood, veneer, and painted surfaces, these punch above their weight.

Recommendation: I recommend these discs for woodworkers, DIYers, and painters who want a reliable, easy-to-use assortment for routine sanding tasks. They’re a smart pick if you value consistent results, solid dust extraction with 8-hole pads, and a sane grit progression in a small pack. For production-level work or heavy stripping, step up to bulk ceramic or mesh options—but keep this set on hand for everything else.
