Boounyatin 4 Inch Hook Loop Sanding Discs Aluminum

Description

Product Overview

The Boounyatin 4‑inch hook‑and‑loop sanding disc system is engineered for versatility and durability. Each disc is constructed from premium aluminum oxide abrasive, offering superior wear resistance and a fine, uniform finish on a wide range of materials. The set comprises ten grit levels—40, 60, 80, 120, 180, 240, 320, 400, 600, and 800—providing a complete progression from coarse material removal to ultra‑smooth polishing. The discs attach to a 4‑inch hook‑and‑loop backing pad (model BO‑3TJ‑ZP) that mounts directly onto the spindle of standard angle grinders without the need for additional adapters. An 8 mm drill adapter is also included, allowing seamless connection to variable‑speed drills, polishers, or other rotary tools. Dimensions of the backing pad are 4 × 4 × 0.1 inches, weighing just 1.19 lb, making it lightweight yet robust for extended use.

Usage

Designed for both professional craftsmen and DIY enthusiasts, these sanding discs excel in automotive bodywork, furniture restoration, metal fabrication, and general home improvement projects. The coarse grits (40‑120) quickly remove rust, paint, or excess material, while the medium and fine grits (180‑400) prepare surfaces for finishing. The ultra‑fine 600 and 800 grits are ideal for polishing metal fixtures, smoothing wood veneers, or achieving a glass‑like finish on plastics. The hook‑and‑loop system enables rapid disc changes, minimizing downtime on the job site.

Why Choose Us

Boounyatin combines rigorous material selection with precise manufacturing tolerances to ensure each disc maintains its shape and abrasive consistency throughout its lifespan. The aluminum oxide formulation resists clogging and heat buildup, reducing the risk of premature wear. Our backing pad features a reinforced fiber core that resists delamination, even under heavy pressure. Every set undergoes a 100‑hour durability test, guaranteeing performance that meets the expectations of demanding tradespeople. Additionally, the inclusion of both a hook‑and‑loop pad and a drill adapter in a single package eliminates the need for separate purchases, delivering exceptional value.

FAQ

Can these discs be used on a standard 4‑inch angle grinder?

Yes, the hook‑and‑loop backing pad is designed to attach directly to the spindle of any standard 4‑inch angle grinder without additional adapters.

What is the recommended speed range for these discs?

For optimal performance, operate the discs between 6,000 and 12,000 RPM. Avoid exceeding the maximum speed rating printed on the disc edge.
