6" x 335" Sanding Belts, 2 PACK

Furniture, door and architectural panel shops run the longer stroke sanders that take a 6" x 335" belt, because a longer table means a full-size door or conference top gets sanded in one pass without repositioning. This is a stroke sanding cloth belt for wood, metal or plastic, and we stock it in Aluminum Oxide for solid wood and veneer, Zirconia for steel and aluminum, and Silicon Carbide for plastics, laminates, solid surface and non-ferrous metal.

All three are poly-cotton cloth belts that can be run wet or dry. Converted in Anaheim, California, two to a pack, 36 through 400 grit. Zirconia is held in the coarse grits; the fine grits are aluminum oxide and silicon carbide.

• Long stroke sander length for full-size doors, conference tops and architectural panels
• Aluminum oxide leaves the even scratch veneer and solid wood need before stain
• Zirconia for steel and aluminum plate on metal stroke sanders
• Silicon carbide for laminates, solid surface, acrylic and between-coat sanding
• 36 through 400 grit; poly-cotton cloth, wet or dry; two belts per pack
• Converted in Anaheim, California; free shipping on orders over $200

Which 6" x 335" belt should you choose?

Match the grain to the material under the pad. On a machine this long a wrong choice wastes a lot of cloth.

• Aluminum Oxide: the belt for solid wood, veneer, plywood and MDF, and the one we recommend to woodworkers almost every time. It cuts cleanly at pad pressure, leaves the most uniform scratch before stain or lacquer and lasts longest on wood. It also works on aluminum, steel and composites when budget matters more than speed. Poly-cotton cloth, wet or dry, in every grit from 36 to 400.
• Zirconia: heavy stock removal and long life on steel, stainless and aluminum. It self-sharpens under moderate-to-heavy pressure, which is more than wood wants, so on wood it tears the grain and burns. Held in the coarse grits, 36 through 120; other coarse zirconia grits can be converted to order.
• Silicon Carbide: the sharpest grain, for plastics, acrylic, laminates, solid surface, fiberglass, stone and non-ferrous metals, and for fine sanding between coats of lacquer or paint where you want the cleanest scratch. It wears fast on steel.

A door shop typically keeps aluminum oxide 100, 150 and 180 on the machine; a metal shop keeps zirconia 60 and 120 with aluminum oxide 220 for graining.

Grit guide for doors, panels and veneer on a stroke sander

What machines take a 6" x 335" belt?

We have not verified individual models against the 6" x 335" size. Stroke sander belt length is fixed by drum spacing, so confirm the length in your manual or measure the old belt before ordering.

• Long-table horizontal stroke sanders with a 6" belt, used for doors, conference tops, architectural panels and casework.
• Metal stroke sanders and long-bed finishing machines that specify a 6" x 335" belt.
• Long edge sanders built around a 6" x 335" loop.

Mounting: back off the tension, carry the belt coiled, slide it over both drums grain side out, check the inside of the belt for a direction arrow before mounting and run it that way, re-tension, then turn the belt by hand and set tracking centered. Re-check tracking after the first minute under load. Other 6" lengths are made to order in about 3 days.

How to get the most out of it

1. Keep the pad flat and moving. The belt cuts only where the pad presses; a tilted or parked pad digs a line or a dish that shows up under finish.
2. Respect veneer. Face veneer is thin. Start at 120, use the lightest pad pressure that still cuts, and watch the color change that tells you the glue line is near.
3. Sand with the grain in long overlapping strokes along the door or panel, then finish with a pass along the rails and stiles separately so cross-grain scratches do not show.
4. Step grits without skipping. 80, 120, 150 or 180 for stain; add 220 only for clear coat.
5. Let zirconia work. On steel, lean on the pad so the grain fractures and keep the part moving so it does not blue.
6. Use silicon carbide for between-coat sanding at 320 or 400 with a very light pad; it leaves the cleanest scratch under the next coat.
7. Keep extraction strong and clean the belt with a crepe rubber belt eraser when finish or resin loads it.
8. Store belts hanging in their coil away from humidity, and let a cold belt warm to room temperature before mounting.

Use it for / don't use it for

Use it for

• Flattening and finishing full-size doors, conference tops and architectural panels (aluminum oxide)
• Levelling veneered panels at 120 and above with a light pad
• Sanding between coats of lacquer or paint (silicon carbide, 320–400)
• Steel and aluminum plate and sheet on a metal stroke sander (zirconia)
• Plastics, laminates, solid surface and fiberglass (silicon carbide)

Don't use it for

• Zirconia on wood; it tears and burns, use aluminum oxide
• Coarse grits on veneer; you will sand through to the glue line
• Silicon carbide on steel; it wears out quickly on ferrous metal
• Grits finer than 220 before stain; the surface burnishes and blotches
• Running against the direction arrow or with a lifted joint
