25" x 60" Metalworking Sanding Belts, 2 PACK

Putting a straight, repeatable grain on stainless sheet is the job a 25-inch Timesaver-type wide belt sander does better than any hand tool, and the belt decides whether that grain comes out even or streaked and heat-tinted. These 25" x 60" Timesaver belts for metal give you the three grains that work: ceramic for stainless and hardened steel under real pressure, zirconia with a grinding aid for mild steel and cooler running on stainless, and cloth aluminum oxide for aluminum and every finishing grit from 150 through 600.

All three sit on a Y-weight polyester-cotton cloth that runs wet or dry, which matters on a graining machine with a coolant head. We convert them in Anaheim, California, two belts to a pack, so a shop can keep the grit it runs most on the shelf without buying a case.

• Ceramic, grinding-aid zirconia and cloth AO, 24–600 grit, one 25" x 60" size
• Y-weight poly-cotton cloth runs wet or dry on coolant-fed graining heads
• Grinding aid in and on the zirconia keeps stainless cool and aluminum from loading
• Ceramic holds a constant cut on 304/316 and hardened steel until it is spent
• Cloth AO 150–600 delivers the even, fine scratch a directional grain needs
• 2-pack format; case pricing and custom lengths on request

Which grain gives the grain finish you want on stainless, steel or aluminum?

Think of these belts in two roles: the coarse and medium grits that remove material, where grain type matters most, and the fine grits that set the visible finish, where technique matters more than grain.

• Ceramic (orange-red): the stock-removal belt for stainless, hardened steel and tool steel when your machine can lean into it. Ceramic renews its cutting points continuously, so it holds a near-constant rate and removes stock cooler than zirconia. Run it at low pressure on a light machine and it glazes, heats the sheet and leaves tint; that is a pressure problem, not a belt problem.
• Zirconia (green or blue): the belt for mild steel plate, tube and A36 fabrications, and the cooler choice on stainless when the machine cannot load ceramic. Ours carries a grinding aid in the resin bond and a second grinding aid coated on top, which lubricates the cut and lowers part temperature. Zirconia is stocked 24–120 grit.
• Cloth A/O (brown): heat-treated aluminum oxide on poly-cotton cloth. Use it for aluminum sheet and plate, brass and copper at every grit, and for all fine graining and pre-polish work, because it is the only grain in this listing at 150, 180, 220, 320, 400 and 600.

For a standard brushed stainless look, most shops finish with AO at 150–220 and then a surface conditioning belt. For a finer satin, continue to 320–400 before the non-woven pass. Not every grain is stocked in every grit; the selector shows the live combinations.

Grit guide: deburr, grain and pre-polish on a 25" x 60" belt

Never jump more than one grade. A 320 belt will not remove an 80 scratch; it will polish the bottom of it and the line reappears under the finish. On aluminum, begin at 60–80 and finish 120–220 before a non-woven belt, using a grease stick if the belt starts to load.

What machines take a 25" x 60" Timesaver belt?

• 25-inch Timesaver-type wide belt sanders set up for metal, whether a dedicated deburring and graining machine or a Timesaver-class woodworking machine converted with a metal-rated dust system.
• 24–25 inch open-end shop wide belt sanders of the Grizzly 24-inch class and SuperMax or Laguna 25-50 style, where the manual specifies a 60-inch loop.
• Single-head deburring machines used on laser, plasma and waterjet parts up to 25 inches wide.

Timesaver is a brand and, in most shops, the generic name for a wide belt sander, so check the actual belt dimensions on your machine plate rather than the name. Width must match; length tolerance on most machines is about plus or minus a quarter inch. We have not verified specific model numbers for this size. If your machine takes a length other than 60 inches, we make it to order in about three days. Check the inside of the belt for a direction arrow before mounting and run it that way if one is printed.

How to get the most out of them

1. Dust and sparks first. Steel sparks or fine aluminum entering a collector with wood dust in it is a fire risk. Use a dedicated metal-rated collector, a spark trap, or wet collection on any machine that runs these belts.
2. Set pressure for the grain. Ceramic and zirconia must be loaded to self-sharpen. If the belt looks shiny and the part is warm, increase depth of cut or feed, or change to a fresh belt; do not slow the conveyor.
3. Keep the sheet moving. Dwell blues stainless. Feed at a constant rate and never stop a part under the head.
4. Grain on the platen. Use the contact drum for 24–120 removal and switch to platen pressure for 150 and finer so the scratch is flat and uniform across the width.
5. Run wet if you can. The poly-cotton backing tolerates coolant, and a wet head produces a cleaner grain on stainless with less tint and no airborne dust.
6. Aluminum runs slower. Lower belt speed, cloth AO or the grinding-aid zirconia, and a grease stick on the running belt when it loads. Clean with a crepe eraser.
7. Store hanging on a wide peg away from humidity and sunlight, and let cold belts reach room temperature before running.

Use it for / don't use it for

Use it for

• Directional graining of stainless sheet, panels and enclosures
• Deburring laser and plasma-cut steel and stainless parts
• Weld knockdown on plate and fabricated frames
• Finishing aluminum sheet, plate and extrusions with cloth AO
• Pre-polish to 400–600 ahead of buffing wheels

Don't use it for

• Wood or MDF on a machine that also runs steel; separate the dust
• A fine finish from ceramic or zirconia above 120 grit; switch to cloth AO
• Ceramic on a machine that cannot apply real pressure
• Running with a lifted joint or against the arrow
