Key Features
Overview
The Festool 490166 Sanding Pad Radius 10 Convex is a profile sanding pad made for the Festool LS 130 in-line sander. This is a sanding pad designed for profile sanding and V-groove sanding on shaped workpieces. Model Number 490166. If you are sanding trim details, custom profiles, or narrow grooves where a standard flat pad leaves high spots and low spots, this accessory gives the LS 130 the shape it needs to stay in contact with the work.
The big reason this pad matters is simple: profile work is where hand sanding usually slows everything down. Festool rates it for sanding V-grooves with an inside radius of 25/64 inch, with a minimum basic V-groove dimension of 3/8 inch. That makes it a practical fit for detail sanding where you need the abrasive to follow the contour instead of just knocking down the edges.
Festool also built this as part of the LS 130 shaping system, so it is not just a replacement pad. It is meant to help you create or match profiles for in-line sanding. The pad measures 3-5/32 x 5-1/8 inches, or 80 x 130 mm, which gives you enough contact area to work controlled passes while still staying focused on the profile instead of drifting onto surrounding surfaces.
On the job, the quick-change design is one of the features you will appreciate most. Toolless pad changes mean you can switch from one profile to another without wasting time digging for screws or extra hardware. If you move between different moldings or shaped parts during the same project, that faster changeover adds up quickly.
The StickFix fastening system is another practical advantage. Abrasive changes are straightforward, which is exactly what you want when you are stepping through grits on finish work. Better abrasive contact and easier grit swaps help you work cleaner on detail sanding, especially when you are trying to keep shaped edges crisp instead of rounded over.
Compatibility is clear here: this sanding pad is for the Festool LS 130. It is a purpose-built accessory, not a general universal sanding block. If you already use the LS 130 for profile sanding, edge work, or detail finish prep, this pad expands what that sander can do in shaped grooves and convex profiles.
This is best suited for woodworkers, finish carpenters, cabinet shops, and anyone doing repeatable profile sanding on trim or shaped parts. It is also a smart pickup for shops that want more control and less hand finishing on custom work. If you do mostly flat sanding, this is too specialized. If you spend real time on moldings, grooves, and profiles, it is the kind of accessory that earns its spot fast.
Dial In Detailed Profile Sanding
When you are sanding shaped parts, the right pad profile is what keeps the surface even. This convex sanding pad is made to follow contours that a flat pad cannot handle properly, which helps reduce uneven pressure on detailed work.
- Designed for sanding V-grooves with an inside radius of 25/64 inch
- Minimum basic V-groove dimension is 3/8 inch
- Made for in-line sanding where control on profiles matters more than raw stock removal
Change Profiles Without Slowing Down
The LS 130 system works best when you can move from one shape to another without turning a simple change into a project. Festool set this pad up for quick, toolless changes, so it fits the way real profile sanding jobs go.
- Toolless pad change allows quick switching between profiles
- StickFix fastening makes abrasive swaps simple between grit changes
- Useful for trim shops, cabinet work, and repeat detail sanding where setup time matters

Pro Tip
If you are sanding delicate profiles, start with a lighter touch than you would on flat stock and let the pad shape do the work. On profile pads like this, too much pressure can round over details that are supposed to stay crisp.
Tool Nut's Take
Festool 490166 Sanding Pad Radius 10 Convex for Detail Work That Flat Pads Miss
The Festool 490166 Sanding Pad Radius 10 Convex is a specialized accessory, but if you own an LS 130 and do profile sanding, it is exactly the kind of add-on that saves handwork and gives you a cleaner result.
- Who it's for: Woodworkers, trim carpenters, and cabinet shops using the LS 130 for shaped edges, grooves, and moldings.
- Why it stands out: It is built around a specific profile, swaps fast, and works with StickFix abrasives, which makes it more practical than trying to fake profile sanding with a flat pad.
- Worth knowing: This is not a general-use sanding pad. It makes the most sense when you regularly sand profiles and already have the Festool LS 130 platform.
