FineStroke – Cordless Reciprocating Detail Sander Kit with 64 Color-Coded Heads added to Cart
★★★★☆
Sander Review: Many things to like: compact size, light weight, color-coded tips, etc. There's a tip for most everything. I do wish the batteries were interchangeable with the HOZO Ultrasonic Knife.

These things are huge which is exactly what we needed! Compressed so many pillows, blankets, quilts, and sheets!!💖
Superb Customer Service. That's how every shop should handle their customers with respect and quickness. Thanks Maria, you were great!
My grand kids loved this and I loved the memories I got to make with them!! It was so easy and the eggs turned out so beautiful and unique
My 3 & 5 year old kids LOVED this. We use it all the time. Something to keep kids minds and hands busy and with their imagination

Precision in Every Pass
Controlled, precise sanding in tight spots, with no over-sanding like rotary tools.
Smooth in Every Detail
Go from rough shaping to polished, mirror-smooth finishes with ease.
8 Head Types for Every Tight Spot
Tight corners, delicate curves or hard-to-reach spots: swap heads quickly and sand with precision, right in your hand.
Pointed Tip
The sharp tip is extremely versatile, perfect for reaching tight spots, intricate grooves and fine details that others can't access.
Flat (Slim)
Ideal for narrow flat surfaces, delicate edges and precise finishing in small or confined spaces.
Flat (Medium)
Suited to medium-sized flat areas, smoothing surfaces efficiently while maintaining full control and precision.
Flat (Large)
Best for quickly smoothing large flat surfaces; works perfectly with foam sandpaper for finer, even results.
Half-Cylinder
Excellent for shaping and smoothing curved surfaces, semi-circular grooves and edges with consistent control.
Arc
Slightly more curved than the Half-Cylinder, perfect for arcs, rounded corners and gently curved surfaces.
Acute Angle (45°)
Sands two angled surfaces at once and fits narrower spots than the Flat (Slim) head.
Right Angle (90°)
Ideal for sanding two perpendicular faces simultaneously, creating precise 90° edges and clean corners.
Color-Coded System
With this setup, your grits always stay sorted and ready to swap. From coarse to fine, just grab the head you need, snap it on and keep sanding.
Adhesive Sandpaper in 8 Grits
The starter kit includes one adhesive sandpaper sheet of each grit level: #180, #240, #400, #600, #800, #1000, #1200 and #1500.
What's in the Box
- Wireless detail sander ×1: Compact, cordless and precision-driven, your core finishing tool for 3D prints, models and fine crafts.
- 64-piece color-coded sanding head collection: 8 head types × 8 pieces each, color-coded by grit level (8 shapes × 8 grits). Pre-load all grits, switch heads instead of sandpaper, and never waste partially used sheets again. Go from shaping to finishing without frequent sandpaper changes.
- Head organizers ×8: One organizer per grit. Color-coded racks with grit labels keep your 64 heads organized by type and grit, so every head is sorted and easy to find: one grit, one color, zero confusion.
- 8-grit sandpaper starter kit ×1: One sheet of each grit level (#180, #240, #400, #600, #800, #1000, #1200, #1500).
- Charging dock with sandpaper storage ×1: Fast-charging station with a Type-C port that charges from 10% to 90% in just 30 minutes. Integrated compartments keep your sandpaper collection organized, flat and protected.
- USB-C charging cable ×1
- User manual ×1
Charging Dock
The charging dock delivers Type-C fast charging, with integrated storage compartments that keep your sandpaper organized, flat and protected. A built-in work tray holds parts and components during sanding, keeping your workpieces secure and your workspace organized.

Frequently Asked Questions
Isn't this basically an "electric toothbrush" with sandpaper?
That's probably the most common comparison, and it's understandable. But not everything that moves with sandpaper is suited to precision sanding. What really matters is how it moves, and how controllable that motion is. This sander uses a true linear back-and-forth motion: not spinning, not wobbling. Combined with a short, adjustable stroke (0.6–1.8 mm) and very low runout (<0.05 mm concentricity), each contact stays stable and predictable instead of bouncing around. Sure, an electric toothbrush or a DIY setup can technically sand, just as hand sanding can get results. But this tool isn't about whether sanding is possible. It's about making fine detail sanding easier to control, more consistent and far less tiring.
At 13,000 SPM, won't it melt plastic?
In fine detail sanding, the sanding head only contacts the surface for very brief moments, giving heat very little time to build up. The reciprocating motion is less aggressive than rotary tools, and plastic melting has been rare in testing. The sander also supports wet sanding with waterproof sandpaper, making it easy to reduce heat further when working on sensitive materials such as resin prints. In normal use, it actually poses less heat risk on plastics than high-speed rotary tools, which maintain constant contact and generate heat far more aggressively.
If I reduce the stroke length, will it stall or lose power?
That's a common issue with many sanding tools, and it comes down to how they're built. Traditional tools use rotary motors, then rely on gears or eccentric mechanisms to turn rotation into sanding motion. At low speeds, especially when you apply side pressure, that system struggles: RPM fluctuates, tools vibrate and stalling becomes more likely. This sander works differently. Its reciprocating linear motor drives the sanding motion directly, with no gears, no eccentric conversion and no power being "translated" through extra mechanisms. Because of this, the output stays smooth, stable and predictable. It doesn't depend on sudden bursts of torque, and it's much less sensitive to load changes.
What does the adjustment slider do?
The slider adjusts the stroke length from 0.6 to 1.8 mm, tailoring the sanding action to your task. Choose a shorter stroke for compact, controlled movements on fine details and delicate areas, or a longer stroke for broader sanding coverage with each movement. The head maintains 13,000 strokes per minute throughout the adjustment range, so even at the shortest stroke you retain rapid sanding action with a smaller, more precise range of movement.
More Questions
Can it be used on metal, car paint or powder coating?
Yes. With appropriate sandpaper, it can be used on metal, automotive paint and powder coating. Its linear reciprocating motion is especially effective for controlled, precision sanding, helping you refine edges, blend surfaces and make small corrections without digging in or overshooting. When accuracy matters, it gives you a level of control that's hard to achieve with conventional rotary tools.
Will sanding hard materials cause the sanding head to move more slowly?
When sanding harder materials, the reciprocating speed, or more precisely the reciprocating frequency, does not actually change. The motor continues to drive the sanding head back and forth at the same rate. However, when greater force is applied and friction increases, the system has to work harder to overcome that resistance. As a result, the stroke length of the sanding head is shortened. In other words, the number of strokes per minute remains the same, but the distance traveled in each stroke becomes shorter. This reduction in stroke length can easily create the impression that the tool is slowing down, when in reality it's the amplitude that changes, not the speed or frequency of the motion.
