Sanding flap disc YATO YT-83271 P36 125 mm, 1 pc

The YATO Flap Disc YT-83271 is a flat 125 mm abrasive disc for angle grinders, intended for general grinding and finishing of metals and for light work on wood and some plastics. Its epoxy-bonded cloth lamellae on a fiberglass backing create a lightweight, damage-resistant disc that can be used without a separate support plate for routine surface preparation and blending tasks.

Advantages

The disc uses alumina abrasive with a synthetic resin bond on a fiberglass backing to provide durable cutting and consistent material removal. Its puck (flat) shape and balanced construction allow stable operation at high speeds, while the epoxy-bonded lamellae improve resistance to wear under typical grinding conditions.

Suitable for

• Shaping and rough grinding of metals
• Surface finishing and blending welds
• Removing rust and paint from metal surfaces
• Light sanding of wood and wood-based materials

When it may not be suitable

This flap disc is not suitable for high-precision woodworking tasks that require finer grits or for any grinding operations that require a backing support disk. It should not be used for prolonged periods at speeds or linear velocities exceeding the specified maximums.

Key specifications

• Diameter: 125 mm
• Grit: P36
• Abrasive material: alumina
• Bond type: synthetic resin (epoxy-based body)
• Backing: fiberglass
• Shape: puck (flat)
• Maximum rotation speed: 12,200 min⁻¹
• Maximum linear velocity: 80 m/s
• Mounting hole diameter: 22.4 mm
• Intended application: metal; also suitable for wood and some plastics

How to use

Fit the flap disc to an angle grinder with a 22.4 mm mounting hole and confirm the grinder is rated for the disc's maximum rotation speed and linear velocity. Secure the disc per the grinder manufacturer's instructions and use appropriate personal protective equipment. Operate with steady, even pressure, moving the grinder across the workpiece and avoiding excessive force or dwelling in one spot to prevent overheating and premature wear.

What to consider before purchase

• Verify the angle grinder spindle and accessory compatibility with a 22.4 mm mounting hole
• Confirm the grinder can safely operate at or above 12,200 min⁻¹ and 80 m/s
• Choose grit P36 for aggressive material removal; select a finer grit for smoother finishes
• Ensure alumina abrasive and the synthetic resin bond are appropriate for the target material

Usage recommendations

For metal work, use moderate speed and continuous movement to blend welds and remove coatings or rust. For wood and plastics, test on scrap material first to avoid gouging or excessive removal; always follow standard safety procedures for grinding.
