150 Grit Aluminum Oxide, 6 in. PS Adhesive Sanding Disc - Qty:5
150 Grit Aluminum Oxide, 6-inch Sanding Disc QTY:5
Production Shops Take Note - No cheap materials used here!
Our PSA (pressure sensitive adhesive) discs are made of full resin-bonded Aluminum Oxide, heavy cloth-backed material, along with an adhesive that holds fast yet does not gum up your backing pad. Ideal for production situations that require discs to hold fast at high speeds and for repetitious, single-grit sanding of flat surfaces. Our competitors often use inferior materials or scrap in the manufacture of their discs.
KLINGSPOR'S WOODWORKING SHOP uses only top-quality industrial goods. You get an extended grit range so that you can pick the perfect finish every time. Each pre-glued disc attaches in seconds; peel off the release paper backing, stick, and sand.
These discs are manufactured from our premium Aluminum Oxide material for wood sanding operations where clogging or loading is a problem. Also great for sanding of soft metals such as brass or bronze.

Aluminum Oxide (AO)
Best for: General-purpose sanding with long belt life.
Aluminum Oxide (AO) is one of the most widely used abrasive grains because it delivers a strong balance of durability, performance, and value. It is manufactured from bauxite and formed into tough, pyramid-shaped grains that wear evenly over time.
As AO wears, it continues to cut—just more finely—making it ideal for multi-stage sanding. Many users extend belt life by moving a partially worn belt from a more aggressive sanding step to a finishing step.
- Top Uses: Bare wood, hardwoods, softwoods, most metals (especially steel), and general shop use
- Best For: Intermediate to finish sanding where consistent results matter
- Why Choose AO: Long-lasting, cost-effective, and versatile across multiple materials
Tip: If you want one abrasive that handles most jobs in the shop, Aluminum Oxide is the go-to choice.
Cloth Backing
Choose your backing based on flexibility and workload.
- J Weight (Light / Flexible):
Ideal for contours, curves, and detailed sanding where the belt needs to flex with the workpiece. - X Weight (Medium / All-Purpose):
The most common backing for general sanding. Works well on portable sanders and wide belt machines. - Y Weight (Heavy Duty / Polyester):
Built for flat surfaces, high pressure, and aggressive sanding. Excellent for heat resistance and durability.
Flex Options:
- J-Flex (JF): Extra flexibility for tight contours, mold sanding, and specialty applications
- X-Flex (XF): More flexibility for slack belt sanding where standard X is too stiff
Backing Selection Tips:
- Use J or JF for curves and detailed work
- Use X or XF for general-purpose sanding
- Use Y (Polyester) for heavy stock removal, flat surfaces, and high heat
Quick Tip: For most woodworking and shop applications, an Aluminum Oxide grain on an X-weight backing is a reliable, go-to combination.
