115x22mm Flap disc 40#-120# (4.5"x7/8") for metal,wood,steel

Product Overview

The alumina flap disc is a high-performance coated abrasive that combines grinding and polishing in one product. Multiple abrasive cloth flaps, specially heat-treated, are evenly bonded in a fan-shaped arrangement onto a backing plate and mounted on an angle grinder for use.

The heat treatment process gives the alumina abrasive higher hardness and thermal stability, keeping it sharp during high-speed grinding. It combines the aggressive cutting power of a grinding wheel with the fine finish of a polishing wheel, enabling grinding and polishing in a single step—effectively reducing workflow and lowering processing costs.

Key Product Parameters

Core Performance Advantages

1.High grinding efficiency: Heat-treated alumina abrasive grains are sharp with excellent self-sharpening properties, offering low resistance and fast grinding.

2.Excellent heat dissipation: The flap structure provides good ventilation and heat dissipation. Combined with the stability of heat-treated brown alumina, it effectively reduces spark generation and workpiece surface discoloration—ideal for heat-sensitive materials like stainless steel.

3.Long service life: After high-temperature heat treatment, the abrasive gains enhanced toughness and significantly improved wear resistance, handling heavy-duty applications.

4.Good flexibility, low noise: Abrasive cloth flaps are flexible, conforming to curved surfaces or weld seams, and operate with low noise.

5.Synchronous wear: The abrasive cloth and backing wear down together, maximizing abrasive utilization.

Main Application Scenarios

1.Metalworking — Weld grinding, slag removal, deburring, and fine surface finishing on stainless steel, carbon steel, aluminum alloy, cast iron, and other metals.

2.Heavy industry — Heavy-duty grinding and polishing in shipbuilding, automotive manufacturing, metallurgy, and steel structure industries.

3.General maintenance — Rust removal, casting cleaning, old coating removal.

4.Non-metallic materials — Grinding and surface treatment of stone, wood, plastic, and other materials.

Choosing Product Type:

T27 (flat): Suitable for flat surface grinding.

T29 (conical): Suitable for weld seams, edges, bevels, and other contoured surface applications.

Choosing Backing Type:

Fiberglass backing offers high strength for heavy-duty applications; plastic backing is cost-effective for light-to-medium grinding.

Product Specifications

Buying Guide

Confirm compatible specifications: Check your angle grinder model to determine the correct outer diameter (100-180mm) and arbor hole (16mm or 22.23mm).

Choose grit based on your needs:

Coarse grinding (36#-60#): Heavy material removal, initial weld grinding, casting cleaning.

Medium grinding (80#-120#): General grinding, surface conditioning.

Fine grinding (180#-400#): Fine polishing, surface finishing.

Choose backing type: Fiberglass/iron backing offers high strength for heavy-duty applications; plastic backing is cost-effective for light-to-medium grinding.

Choose product type: T27 (flat) is suitable for flat surface grinding; T29 (conical) is suitable for weld seams, edges, bevels, and other contoured surface applications.

Safety Instructions

Before use, confirm that the product's maximum speed is not lower than the angle grinder's speed, and install according to specifications.

During operation, wear personal protective equipment including safety goggles, face shield, earplugs, and dust mask.
