DeWalt‘s random orbital sanders are common on UK construction sites and in workshops. Like Makita and Bosch, DeWalt uses an 8-hole pad system, which means disc compatibility with competing brands is straightforward—but pad compatibility is not.
This guide covers DeWalt sander models, explains which pads and discs fit, shows you how to cross-reference abrasives across brands, and provides part numbers for replacement pads and batteries for the cordless DCW210B.
DeWalt Sander Models and Specifications
DeWalt makes a consistent line of 125mm (5-inch) corded and cordless random orbital sanders. All use the same pad system.
| Model | Pad Size (mm) | Hole Pattern | Orbit (mm) | Power |
|---|---|---|---|---|
| DWE6423 | 125 dia. | 8-hole hook-and-loop | 2.6 (random) | 280W corded |
| DCW210B | 125 dia. | 8-hole hook-and-loop | n/a | 20V MAX / 18V XR cordless |

The DeWalt 125mm 8-Hole System
DeWalt’s 125mm sanders (DWE6423, DCW210) take 125mm 8-hole discs; DeWalt also makes the 150mm DCW230. This is identical in size to the Makita system, though mounting hardware is brand-specific.
Hook-and-Loop Backing
Every DeWalt pad uses hook-and-loop (velcro-style) backing. Benefits:
- Instant disc attachment and removal
- No adhesive residue
- Easy mid-job disc changes
- Low cost per disc
Dust Extraction Design
The 8 holes route dust to the dust bag or an external extractor.
DeWalt Replacement Pads
Always use OEM DeWalt pads for replacement. They’re engineered to maintain pad flatness and orbital consistency.
| Model(s) | OEM Part Number | Pad Density | Price (approx.) |
|---|---|---|---|
| DWE6423, DWE6421 | DWE64233 | Medium | £8–11 |
Pad density: The medium pad (DWE64233) is standard and suitable for flat surfaces. The soft pad (N103968) conforms better to uneven or curved surfaces. Most users need only the medium pad; buy soft if you sand mouldings or profiles regularly.
DeWalt Abrasives: Sanding Discs and Grits
DeWalt sells 125mm 8-hole discs, such as DT3103-QZ (80 grit) and DT3115-QZ (120 grit).
DeWalt Sanding Disc Range
- Wood abrasives: Closed-coat, standard for wood and composites. P60–P150 most common.
- Fine finish abrasives: P180–P220 for final passes and veneers.
- Assortments: Multi-grit 10-pack or 50-pack bundles offer good value.

Cross-Brand Compatibility: DeWalt vs Makita vs Bosch
Understanding compatibility is essential if you own sanders from multiple brands or are considering switching.
Disc Compatibility (8-Hole Discs Are Universal)
All 8-hole abrasive discs—regardless of brand—physically fit any 8-hole pad. This includes:
- DeWalt discs on Makita or Bosch pads
- Makita discs on DeWalt pads
- Third-party brands (Mirka, 3M, Sia, etc.) on any brand’s pad
Why this works: The 8-hole pattern is an industry standard. Hole size, spacing, and arrangement are identical across all brands using 8-hole systems.
Trade-off: Dust extraction efficiency is slightly compromised with cross-brand discs because hole positions don’t perfectly align with each sander’s dust ports. However, performance remains excellent. Use matched discs (DeWalt on DeWalt) for optimal dust capture.
Pad Compatibility (Brand-Specific Only)
Critical point: pads are NOT interchangeable between brands, even though discs are.
| Brand | Pad Size (mm) | Mounting Type | Screw Holes | Compatible With |
|---|---|---|---|---|
| DeWalt DWE6423 | 125 dia. | Four screws | DeWalt-specific | DeWalt only |
| Makita BO50xx | 123 dia. | Screw-in | Makita-specific | Makita only |
| Bosch PEX 125 | 125 dia. | Screw-in | Bosch-specific | Bosch only |
Bottom line: If your DeWalt pad wears out, buy the DeWalt pad listed for your sander. However, you can use 8-hole discs from any brand.
DeWalt Cordless Sanders: DCW210B and 20V MAX Battery Compatibility
The DCW210B is DeWalt‘s cordless random orbital sander, powered by DeWalt’s 20V MAX batteries (DeWalt rates 20V MAX at 18V nominal; its UK cordless range is branded 18V XR). It uses the same 125mm 8-hole pad as DeWalt‘s corded models.
Battery Compatibility
The DCW210B works with all DeWalt 20V MAX batteries, including:
- DCB183: 2.0Ah
- DCB184: 5.0Ah
- DCB185: 1.3Ah
- DCB205: 5.0Ah
- DCB206: 6.0Ah
For sanding work, a 5.0Ah pack such as the DCB205 is a sensible choice, and the DCB206 (6.0Ah) runs longer between charges; DeWalt does not publish a sanding runtime. Pair it with a second battery for all-day cordless work.
Best Sanding Discs for DeWalt Sanders

Frequently Asked Questions
Can I use Makita discs on my DeWalt sander?
Yes, completely. 8-hole discs are universal across all brands. A Makita or Bosch 125mm 8-hole disc will fit your DeWalt pad perfectly. Dust extraction will be marginally less optimised than with DeWalt-branded discs (because hole positions may not align exactly with DeWalt‘s dust ports), but performance remains excellent for most work.
How long does a DeWalt sanding pad last?
In a busy workshop (daily use), expect 50–100 hours of effective use before the hook-and-loop backing loses grip or the pad surface becomes uneven. In casual workshops (weekend use), a pad can last 1–2 years. Replace when discs no longer grip securely or the pad develops a concave surface.
What grit should I use for wood sanding?
P40–P60: Rough stock removal, old paint stripping, heavy smoothing. P80–P120: General-purpose work, stock removal, intermediate smoothing. P150–P180: Fine finishing, veneers, final prep before stain/seal. P220: Ultra-fine finishing, sealant/paint prep, high-end cabinetry.
Is the cordless DCW210B as powerful as the corded DWE6423?
The corded DWE6423 (280W) is not limited by battery. The cordless DCW210B with a fresh 5.0Ah or 6.0Ah battery delivers comparable performance for most tasks. The trade-off is runtime: cordless runs for as long as its battery lasts (DeWalt does not publish a sanding runtime); corded works indefinitely. For workshop and light commercial use, cordless is increasingly practical.
Can I fit a DeWalt pad on a Makita sander?
No, pads are brand-specific. Screw hole spacing is different between brands. You must purchase the original brand’s replacement pad. However, you can use 8-hole discs from any brand (including DeWalt discs) on any brand’s pad.
Where can I buy DeWalt replacement pads and discs in the UK?
Amazon stocks both OEM DeWalt pads and third-party discs with fast delivery. Screwfix and Toolstation carry DeWalt replacement pads for click-and-collect within 1 hour. Specialist suppliers like Axminster carry premium alternatives like Mirka, 3M Cubitron II, and Sia.
How we compile this guide
We cross-reference compatibility details against manufacturer specifications where available, official tool manuals, and the physical standards that govern fitment (bore sizes, arbor diameters, voltage platforms, connector types). We prioritise primary sources over retailer listings, flag anything we can’t confirm, and re-verify the data on a regular cycle. Where we give a buying recommendation, we tell you the reasoning — not just the link. More on our method →
