Arbortech Contour Sander | 50mm Mini Random Orbit Attachment for Angle Grinder | SAN.FG.210.20

Overview

Meet the Arbortech Contour Sander—a purpose-built sanding attachment designed to live on your angle grinder. It excels at shaping free-form internal curves, such as shells and deep internal profiles, offering a level of control that is hard to match with bulkier tools. This compact tool invites you to experiment with organic shapes and rounded edges, turning challenging work into a more manageable process.

Designed for curves and hollows

The core advantage is the mini orbital motion paired with a patented Flexible Backing Pad. This combination helps you achieve a smooth, uniform finish on complex shapes while reducing the risk of scarring or blemishes on the wood. The 8 cm (3 1/6 in) shaft length lets you reach into deep hollows that would otherwise be difficult to access, expanding what you can reach without repositioning your setup.

What makes this sander stand out

• Performance: A specialized sanding attachment for angle grinders that targets free-form internal curves and deep profiles
• Flexibility: The mini orbital action with the flexible backing pad delivers a refined surface with less risk of marking the wood
• Quality: Arbortech tools are built to last and designed for detailed and spot sanding tasks
• Compatibility: Attaches to most standard 100mm (4 in) or 115mm (4.5 in) grinders
• What’s included: A sanding paper set with assorted discs for immediate use

In real-world projects, you can use it to shape curved edges on furniture, smooth shells in sculpture work, or refine inside contours of wooden components where a traditional block plane would struggle. The tool shines in delicate detail work where control matters as much as speed.

Practical guidance

• Pair with the ARBORTECH Power Carving Unit for optimized workflow in certain setups
• Choose the right disc grits to balance material removal with surface quality for your project
• Keep the backing pad flexible and change discs as needed to maintain consistent contact

Included with the attachment is a versatile sanding discs set, ensuring you have the right grits for different stages of your project. This setup supports detail sanding and spot sanding, enabling you to address fine features without overworking the surrounding wood. While results will vary by material and technique, the Contour Sander offers a controlled path toward a refined finish on curved and recessed surfaces.
