IVY Classic 43100 4-in x 24-in 36 Grit Sanding Belt - Extra Coarse

In this review the IVY Classic 43100 Flex-Abrasive 4-in x 24-in 36 grit sanding belt is evaluated for DIYers and pros who need an extra coarse abrasive for rapid material removal. The bottom line: it is best for aggressive sanding of wood, metal, plastic and fiberglass where cutting speed and long belt life matter. The reviewer found the belts deliver strong sanding ability and value for money, with a diagonal lap splice that reduces the common splice bump and a note to always sand in the direction of the arrow to get the longest life.

Key Features

• Extra coarse 36 grit: Cuts material quickly for stripping paint, shaping wood and removing rust without excessive clogging.
• Resin cloth construction: Offers durability and long life under heavy use compared with paper belts, making them suited to repeated jobs.
• Diagonal lap splice: Minimizes the splice bump for smoother passes and less marking on the workpiece when used correctly.
• X weight aluminum oxide abrasive: Provides consistent cutting performance across wood, metal, plastic and fiberglass.
• Direction marked by arrow: Ensures users run the belt the right way for maximum performance and reduced premature failures.

Who It's For

The IVY Classic 43100 belt is ideal for home workshop owners, auto body hobbyists and professional tradespeople who need a durable extra coarse belt for rapid material removal and blending welds. Its resin cloth and aluminum oxide formulation suit repeated use across mixed materials where long belt life matters.

Those who should look elsewhere include users who need very fine finishing grits for final sanding or those who require specialty ceramic or zirconia belts for extreme metalworking; for light touch finishing a higher grit belt would be a better choice.

Pros & Cons
