4 x 24 in Sanding Belts 36 Pack - Assorted Grits for Belt Sanders

Our review of this 4 x 24 in sanding belt assortment finds it best for woodworkers and hobbyists who need a wide range of grits in one kit; the single biggest reason to buy is the convenient set of six common grit options so you can move from aggressive material removal to fine finishing without hunting for individual belts. The review covers performance on wood and light metals, fit with common sanders, and durability observed by users, giving a practical picture of where this assortment fits into a workshop.

Key Features

• Assortment: Six each of 60, 80, 120, 150, 240 and 400 grit gives a complete progression from coarse stripping to fine polishing for staged sanding work.
• Material: Open coat aluminum oxide grain handles a variety of substrates so users can sand wood, non-ferrous metals, fiberglass and plastics with one belt type.
• Backing: X-weight clothed backing provides a durable support that resists tearing during heavy-duty stripping and shaping tasks.
• Bonding: A resin on resin bond aims to extend belt life under frequent use and minimize premature breakdown under heat.
• Compatibility: Sized for 4 x 24 in belt sanders and listed to work with a number of common oscillating and belt sander models for straightforward fit and replacement.

Who It's For

This assortment is ideal for DIY woodworkers, hobbyists, and small shop owners who want a single pack that covers coarse to fine grits for shaping, smoothing and finishing projects. It suits users who switch frequently between aggressive material removal and finer finishing without stocking separate belts.

Those who need belts for heavy industrial production or for highly abrasive metal removal should look for a specialty abrasive optimized for that continuous, high-heat work. Buyers who require guaranteed seam adhesive strength for nonstop production runs may prefer premium industrial belts with documented seam warranties.

Pros & Cons

Pros

• Good value: the 36-belt pack supplies a full grit progression so projects can move from rough to fine without extra purchases.
• Versatile abrasive: aluminum oxide open coat works across wood, light metals, fiberglass and plastic for multi-material shops.
• Convenient fit: standard 4 x 24 in size and reinforced backing make these simple replacements for common belt sanders and oscillating spindles.

Cons

• Mixed durability reports: some users report belts or seam adhesive failing quickly, so occasional early failures may occur under heavy use.
