Sander accessory YATO YT-83275, pack of 1

The YATO Flap Disc 125 mm, Grit P100 (model YT-83275) is an abrasive flap sanding disc supplied as a single unit for use as a replacement or add-on part for compatible angle grinders. With a 125 mm diameter and flat puck shape, this flap disc is intended for medium-fine material removal and finishing on metal, wood and some plastics. Overlapping cloth lamellae bonded with epoxy resin on a fiberglass backing provide uniform cutting action and a consistent surface finish for tasks such as deburring, rust removal, weld blending and surface preparation in workshop and construction environments.

Advantages

The epoxy-bonded lamellae form a lightweight, durable assembly that resists damage and maintains abrasive performance during use. P100 grit offers a balance between material removal rate and surface quality, delivering a medium-fine finish on a range of substrates. Fiberglass backing adds stability at high speed while the alumina abrasive provides reliable cutting on ferrous metals and wood. The disc’s standardized mounting hole enables fitting to common angle grinders and the specified maximum rotational and linear velocity ratings are suitable for typical handheld grinding applications.

Suitable for

• Deburring and edge shaping of metal parts
• Rust and scale removal from steel surfaces
• Weld seam blending and smoothing
• Sanding and leveling of wood and wood-based panels
• Light stock removal and surface preparation before painting or coating

How to use

Fit the flap disc to an angle grinder that accepts a 22.4 mm mounting hole and verify the grinder’s maximum speed does not exceed the disc’s rated 12,200 min⁻¹ and 80 m/s linear velocity. Securely mount the disc following the grinder manufacturer’s instructions and ensure the workpiece is firmly clamped. Start the grinder and allow it to reach full speed before applying light, even pressure to the work surface, moving the disc across the area to avoid gouging. Use steady, overlapping passes to achieve a consistent finish and replace the disc when the abrasive lamellae are worn or performance decreases.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Avoid excessive pressure or side-loading on the disc; allow the abrasive to perform the cutting. Work at a moderate angle and maintain movement to prevent overheating when working on metal. When switching between metal and wood, consider changing discs to avoid cross-contamination and to preserve surface finish quality.
