A LARGE DISC AMPLIFIES PAD AND INSTALLATION ERRORS
Center the disc on a flat compatible eight-inch attachment surface
The X-weight cloth and resin bond support demanding sanding, while the PSA liner provides direct attachment to a compatible clean pad or steel platen. Exact diameter, pad flatness, speed, work rest, pressure, and grit progression all matter.
Nine live grit choices
All variants use aluminum oxide, from coarse 36 grit through fine 400 grit.

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.
Coarse shaping and stock removal
Use the least aggressive coarse grit that performs the required removal while preserving control near edges and corners.
Intermediate scratch refinement
Use to remove the prior coarse scratch and prepare the surface for finer sanding or an appropriate finish system.
Fine surface preparation
Use after the prior scratch is uniform. The final acceptable grit depends on the material, coating, adhesive, or finish that follows.
X-weight cloth on a clean flat pad or platen
Center and press the disc evenly. A distorted, contaminated, overheated, or incorrect attachment surface can create poor adhesion or uneven sanding.
CLOTH PSA CONSTRUCTION
What are you buying—and what else does the system need?
Each disc combines abrasive grain, resin bond, X-weight cloth backing, and a pressure-sensitive adhesive liner. The compatible backup pad or steel platen, tool, and work support are separate parts of the sanding system.
Grain and grit control the cutting stage
Use the live variant name as the product specification. Different grain families have different available ranges, and a higher-priced grain is not automatically right for every job.
The bond anchors grain to the cloth
Heat resistance does not remove system limits. Monitor temperature, loading, edge wear, backing condition, and any change in attachment during use.
Tough backing for demanding sanding
Cloth is more durable than lightweight paper in many heavy or edge-wear applications, but it is less compliant for fine paint-preparation work and must still match the pad and tool.
Peel, center, press, and remove
Pressure-sensitive adhesive attaches directly to a clean compatible surface. It is not hook-and-loop, and a damaged, oily, dusty, overheated, or wrong-size pad can compromise the attachment.

How to install a cloth PSA sanding disc
Match the disc to the attachment surface
PSA uses adhesive contact across the back of the disc. Hook-and-loop uses mating textile faces. Do not place one system directly on the other unless the tool manufacturer approves a purpose-built interface.
Do not generalize wet-use claims. Use liquid only when the exact disc, adhesive, pad, machine, electrical setup, work material, and operating procedure are approved for it.
HOW TO USE IT
Install the eight-inch PSA disc without wrinkles or offset
Follow the machine and pad instructions for power isolation, diameter, speed, guarding, work rest, extraction, pressure, and disc removal.
- 01
Disconnect power and confirm the machine accepts an 8-inch cloth PSA disc and the selected grit.
- 02
Inspect and clean the pad or steel platen; it must be flat, dry, undamaged, and compatible.
- 03
Peel the liner, center the disc carefully, and press it flat from the center outward.
- 04
Run clear of the work and verify the disc is secure and true before a light test pass.
- 05
Use supported, controlled contact; stop fully before removing the disc or adjusting the work rest.
Use the guarding, extraction or collection, personal protective equipment, training, and operating procedures required by the machine, abrasive product, work material, and workplace.
Use it for
- Compatible 8-inch disc sanders and PSA attachment surfaces
- Flat sanding, edge shaping, and surface preparation
- Wood or metal work qualified for aluminum oxide
- Coarse removal through 400-grit refinement
- Stationary-disc work with the required table, guard, and extraction
Do not use it for
- A 6-inch, 9-inch, hook-and-loop-only, or otherwise incompatible pad
- Using the unsupported side or prohibited area of a stationary disc
- A wrinkled, off-center, damaged, or lifting disc
- Wet sanding without explicit system approval
- Using force instead of choosing an appropriate starting grit
PRODUCT FAQ
Questions before you choose?
What comes in each 8-inch cloth PSA disc order?
Each selected variant contains 20 matching 8-inch aluminum oxide cloth PSA discs in one grit.
Which grits are available?
The live selector offers 36, 60, 80, 120, 150, 180, 220, 320, and 400 grit.
What machines can use these discs?
Use only equipment with a compatible 8-inch PSA backup pad or steel platen that is approved for the cloth disc, speed, guarding, work support, material, and process.
Are these hook-and-loop discs?
No. They use pressure-sensitive adhesive and require a compatible clean PSA attachment surface.
How should I choose the starting grit?
Begin with the least aggressive grit that removes the defect or shapes the part efficiently, then use the intermediate stages needed to erase that scratch before the target finish.
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.
