Best Detail Sander for Spindles: 2025 Expert Review
DR Joinery
Expert Joiner & Staircase Specialist
Refinishing a staircase is one of the most rewarding home improvements, but sanding the spindles (balusters) is notoriously the most hated job in the trade. The intricate curves, tight corners, and sheer repetition can turn a weekend project into a month-long ordeal if you don't have the right kit.
In many of York's older properties, the spindles are often coated in layers of thick gloss or varnish that hides the detail. Using a standard orbital sander on these curved surfaces simply flattens the profile, ruining the craftsmanship. You need a tool small enough to respect the curves but powerful enough to strip the finish.
In this review, I'll compare three options: a budget-friendly mouse sander for light work, a high-power handheld unit for stripping, and a professional benchtop spindle sander for those undertaking a full dismantle-and-restore project.

Specs vs. The Real World
The Spec: "Dust Extraction Claims"
"Manufacturers claim 'dust-free sanding' with built-in micro-filters."
When sanding spindles, the sanding pad rarely makes full contact with the wood due to the curves. This breaks the vacuum seal, meaning dust goes everywhere. Always wear a decent mask, regardless of the claim.
The Spec: "Reach 'Any' Corner"
"Pointed tips allow you to sand 100% of the detail."
Detail sanders get you 95% of the way there. For the tightest quirks in turned timber, nothing beats a folded piece of abrasive paper and your own thumb. Don't expect the machine to do the absolute final finish in the crevices.
My Top 3 Recommendations
Three options to cover different needs and budgets
55W Compact Electric Mouse Sander with 15 Accessories
BLACK+DECKER
For most DIYers freshening up a staircase in situ, this is the go-to tool. It's lightweight, comes with a specific 'finger' attachment for reaching between spindles, and has enough power for finishing work without being too aggressive on delicate softwood.
The Good
- Includes a finger attachment specifically designed for tight spindle gaps
- Lightweight design reduces fatigue when working vertically
- Good variety of sanding sheets included
The Bad
- 55W motor struggles with heavy paint stripping
- Dust collection is minimal on curved surfaces
Installer Tip:
Use the finger attachment for the 'quirks' (the sharp recesses in the turning). Don't press too hard with the tip, or you'll melt the hook-and-loop backing. let the speed of the tool do the work.

Triton
This is a serious joinery tool. It is not handheld; it sits on a bench. If you are removing spindles to restore them, or making new oak spindles from scratch, this is the only tool that yields a factory finish. The oscillating action prevents burning and ensures perfectly smooth curves.
The Good
- Oscillating action prevents sanding marks and burning
- Ideal for shaping and finishing intricate curves
- Cast aluminium table ensures accuracy
The Bad
- Not portable – cannot use on fixed staircases
- Significantly higher price point
- Large footprint requires workshop space
Installer Tip:
If you are replacing a few broken spindles in a Victorian property, take the new timber to this machine before installation. It's impossible to get this quality of finish once the spindle is fixed in the staircase.

DEKOPRO
This tool solves the problem of removing stubborn varnish in tight spaces. With a 180W motor, it has significantly more 'grunt' than standard detail sanders, making it excellent for the initial stripping phase on hard hardwoods like oak or mahogany.
The Good
- High power (180W) makes quick work of old varnish
- Very affordable price point
- Compact body fits well between balusters
The Bad
- Aggressive removal requires care on soft woods
- Vibration is higher due to powerful motor
Installer Tip:
Because this has a stronger motor than the Black+Decker, use it for the initial 'keys' (roughing up or stripping). Start with an 80 grit to strip, then switch to a finer tool or hand sanding for the finish to avoid leaving swirl marks.
