DECISION GUIDE
What should you verify before choosing?
The exact fit, abrasive construction, grit, machine setup, work material, and finish target all affect the result.
36–400 grit general-purpose range
Choose for the broadest progression across wood, general metal, detail sanding, and finish preparation when the material and process are compatible.
36–120 grit tough removal range
Use for demanding coarse and medium work where enough appropriate pressure is available to keep the abrasive cutting.
36–120 grit pressure-responsive range
Ceramic grain is designed to microfracture under load and is commonly selected for demanding ferrous grinding. Avoid light-pressure use that only glazes the belt.
Edge, bevel, flat, and irregular-shape work
Use the exposed-pulley or platen contact area specified by the tool, keep the belt moving, and test speed and pressure on scrap first.

PRODUCT FAQ
Questions before you choose?
Will these belts fit a Makita 9031?
Makita identifies the 9031 as a 1-1/8-inch × 21-inch belt sander, and the original product page references that model. Confirm the exact tool, belt direction, and current accessory requirements before ordering.
What comes in each order?
Each selected variant contains 40 matching belts in one abrasive material and grit.
Which abrasive should I choose?
Aluminum oxide offers the broadest general-purpose and fine-grit range. Zirconia is a tough coarse-to-medium option. Ceramic is pressure-responsive and aimed at demanding ferrous grinding. Match the choice to material, pressure, heat, and finish target.
Which grits are available?
Aluminum oxide is listed from 36 through 400 grit. Zirconia is listed from 36 through 120 grit, and ceramic in 36, 40, 60, 80, and 120 grit.
Are the old lifespan multipliers guaranteed?
No universal life multiplier is promised. Belt life varies with material, speed, pressure, contact area, heat, loading, tracking, and operator technique.
What are the shipping and return terms?
Shipping methods, rates, and delivery estimates depend on the order and destination and are shown at checkout. The return policy provides a 30-day window for eligible unused items in original condition and packaging. Restrictions and return-shipping costs apply.
